Busy Day Of Banding

This is a photo that Larry Sirvio took of Tennessee warbler at Carpenter Nature Center--one of the 47 some odd birds that we banded this morning. Oy.

It was just nuts at banding today--I barely had any time to get photos. I arrived a little late and noticed some of the parking lot was getting ready to be repaved. I thought to myself, "With all this construction activity, I bet it will be slow." As I walked towards the building, I noticed one of the nets hadn't been put up yet. I thought it strange, but figured with the construction, maybe they weren't putting all the nets up.

Larry passed me and said, "They just radioed, there are eight birds in the orchard nets. There's one over there too." I said I would put my stuff down and start helping. Inside, the other volunteers were furiously looking up small flycatcher identifications, and there were already about six bags with birds hanging waiting their turn to be processed (from a quick glance the bags had warblers, vireos, a red-breasted nuthatch, and some sort of small flycatchers). Yikes!

From there it was just a blur. At one point I was at a net with one of the Carpenter naturalists. There were four birds in the net. While we were trying to get them out, four more flew in, and then another two. We decided that it was so backed up in processing that we would close up the nets until we were caught up. By the time we got to the last net, eight birds had flown in. We were running out of bags, but fortunately, they were all mostly goldfinches and we could put more than one in a bag.

This is one of the juvenile chipping sparrows we got in--they don't quite look like the adults, about the only thing that really gives them away is the eye stripe and the chipping noise that the make as you untangle them from the nets. We did get in a rather exciting adult--it had a band and turns out that it was banded for the first time on June 17, 2005 and at the time of banding it was already an after hatch year bird, which means that by now it is well over three years old!

This young catbird looks like it is off to a rough start. First, notice all the pin feathers--it's just growing in its cap. But towards the back of the head, its missing some feather and skin--something poked it, hard. Was it a nest mate? Was it a blue jay trying to attach the young in the nest? Who can say. It reminded me of the red-headed woodpecker we got in last year.

And it's interesting to note how different birds feel in the hand. Above is a male Wilson's warbler that I got out of the net. He felt so tiny, like I would break him. The easiest way to get birds out is to grab the feet and untangle those. Most of the time, if you can get the feet out, you can get the rest of the bird fairly easily. Most of the time.

Volunteer Dennis Donath go this photo of a female Wilson's warbler (note the lack of black cap). Today was good practice for untangling birds from the net, I just kept doing the over and over. The goal is to get birds out quickly. Usually, when a bird is REALLY tangled, I defer to the more experienced banders to get the bird out. However, everyone was so busy today, that a coupe of times I found that I was the only option and just had to muddle through. Sometimes, when I'm trying to get out a really tangled bird, I panic. My hands start to shake uncontrollably and are completely useless. When that happens, I just have to let go, take a step back, take a few deep breaths, understand that my panic is not going to help the situation and then go back to the task at hand.

Above, Jim Fox is handing a Wilson's warbler to a young girl whose family came to visit today. Sometimes, you can place a warbler on its back and it will lay there for a moment before flying away. That gives the kid holding it a chance to marvel at the magic of the the little thing in their hands. I got a five second video. Note the little girl's face.

Tell me that she's not now hooked on birds.

I'm still kind of learning the ropes at banding. I'm now to the point where I can actually band a few birds. I insisted that the first practice birds be ones like cowbirds--let me mess up on a cowbird, not a warbler. But I'm to the point that today, when I got an ovenbird out of the net, I got to band it myself--WHOOT!

First, let me say that after handling other warblers from the nets, the ovenbird is much chunkier. That is one beefy warbler--very chunky. You don't really get a chance to notice that when their flitting about in the wild. I'm happy to report that I banded it, aged it (after hatch year--at least a year old) and sexed it (unknown). We got some photos and let it continue on its southward journey.

Today was the first day of sun after six days of non stop clouds and rain. I finally noticed that migration in Minnesota is sincerely underway. If you have a chance, get out and enjoy it while you can.

Lawrence's Warbler?

As if fall warblers weren't already tricky to identify! Here comes a whopper.

All the photos in this blog entry were taken by bird bander Mary Messerli. She and Robert Fashingbauer were banding birds near Willow River State Park in Wisconsin on August 15, 2007 when they banded these two unusual warblers. Take a look at this:

At first glance this looks like a golden-winged warbler, however it has way too much yellow. If some of you are jumping to a hybrid conclusion, you are right. Sometimes golden-winged warblers will hybridize with blue-winged warblers.

When a golden-winged warbler mates with a blue-winged warbler, you usually get a hybrid called a Brewster's warbler. This bird doesn't look anything like a Brewster's. It has the masking of a golden-winged, but the yellow wash of the blue-winged warblers. This bird is a backcross--one of it's parents was a Brewster's and the other was either a true golden-winged warbler or true blue-winged warbler. When this happens you get another type of hybrid called a Lawrence's warbler. Confused yet? Were you able to follow that? Well, hold onto your hat, it gets even trickier:

That same day, those banders caught this bird--another hybrid. Oy! The banders said that this bird had characteristics of being a hatch year bird (it came out of the egg this year) the bird above had characteristics of being an after hatch year bird (at least a year old). But really, it's hard enough to identify hybrids and even harder to age and sex them. I think this is another Lawrence's warbler backcross (a Brewster's hybrid that bred with either a true golden-winged or blue-winged warbler). The banders felt that this bird is of unknown sex, but with the pale mask, I think it is reminiscent of a female golden-winged warbler, so I'd be willing to go out on a limb and call this female.

I nipped over to BNA Online to see what they had to say about hybrids and found this:

"Molecular analyses of hybridization indicate that Blue-wing mtDNA introgresses asymmetrically and perhaps rapidly into Golden-wing phenotypes without comparable reverse introgression and footprinting of Golden-wing mtDNA into replacement Blue-wing populations."

Holy crap, I though Pyle was hard enough to read. Basically, (I think) this is saying is that all this hybridizing and backcrossing can result in fewer golden-winged warblers and more blue-winged warblers. The hybrids and the backcrosses end up in future generations breeding into blue-winged warblers.

Banded Sandpipers

Remember the banded semi-palmated sandpiper we found over the weekend along Duck Banding Road on Big Stone NWR? Well, Doug Buri found out where and when it was banded from Nate Thomas, the doctoral candidate working on tracking them:

The first bird was banded about 2 miles south of Salt Lake on the Minnesota/South Dakota border on July 21-23 2004. That means that the bird is at least 3 years old! Since we couldn't read the individual band number, we don't know if it was tagged as an adult or an immature bird but it has been surviving and migrating since 2004! WOW!

I didn't mention that on our final field trip, we found a second banded semi-palmated sandpiper with different colored tags. I can tell you from my other banding experiences that finding recovered birds is unusual, but finding two banded birds in a weekend--that's unbelievably rare. Again, we couldn't read the individual band number, but based on the color marks on its legs, Nate said the bird was banded in either 2003 or 2005, making the bird either 4 or 2 years old.

These birds breed in the Arctic and migrate down to South America for the winter. Think of the thousands of miles they cover year after year--I'm still trying to wrap my head around that one. What is this saying about migratory route fidelity? So, if you are lucky enough to see any shorebirds in your neck of the woods, even if you can't identify them, think about the migratory journey they could be on.

An Exciting Day

I'm too wiped out to do a proper entry, but I will leave you with some exciting bits from the day. First up, can you identify the bird in the above photo? Hint: It's not a shorebird. When you're ready to guess, the adult plumaged bird can be seen here. No prize, just glory in the comments section.

Second, I met someone totally cool (in my book) on the trip. Long time readers of this blog may recall that I am a big fan of the crop art at the Minnesota State Fair. One of my all time favorite pieces was a portrait of Jackie Chan in 2005. Turns out that one of the women taking the shorebird workshop not only does crop art, but her husband did the Jackie Chan portrait (I totally geeked out). I told her that her cool points had just sky rocketed in my book. Between that and the fact that there is a Strong Bad sticker on her car, leads me to believe that we could be friends outside of birding--if my overwhelming (but sincere) excitement over crop art didn't frighten her. I'm not sure she wants me to completely out her or her husband as crop artists, but I will say that if you visit Cropart.com they have some work up in the gallery section.

Take note of the above photo. Notice anything out of the ordinary? Note the bird coming in for a landing. Do you see tags on the legs?

We found a tagged semi-palmated sandpiper! Normally, I would say that finding a tagged bird is excitement enough--we'll report it, find out where it was banded, how old it is, etc. But I'm even more excited that when it flew in, I was able to tell the trip leader that we had a tagged semi-palmated sandpiper...I identified a semi-palmated sandpiper on my own (sniff, sniff) I've had a total breakthrough!

Friday's Fun At Carpenter

But first, a wee bit of bragging. My sister, Terri N. Graves has a front page article in the current issue of NatureScape News! If you have a copy, it's the one with the blue dragonfly photo. If you don't have one, go out and buy it right now--it's a great paper and my sister is a great writer, a bit different from me--perhaps a tad more conservative...and not as many typos. Here's her profile on their website, but here is what she actually looks like. I think she's going to be a regular contributor to their publication and I'm so excited for her. She'll write on birds, flowers, dragonflies, or whatever tickles her outdoor fancy. NatureScape News covers the whole Midwest and Terri will be their Indiana field contributor, giving her Hoosier perspective. Go, Terri! Whoot.

Well, it was a mini bogging conference on Friday at Carpenter Nature Center because Hasty Brook and Hell Ziggy showed up to join in the fun. I learned that I am not ready to get black-capped chickadees out of the nets on my own. You would be surprised at how hard they are to retrieve, because they ball up their little toes around the nets, and you have to get their feet out before you get the rest of their little bodies out. Problem is, as soon as you get the toes out, they sneak in and clamp down on more net. My particular chickadee had fluttered quite a bit and was beyond tangled. It had to be cut out, which I didn't enjoy, since banding nets cost about $70--ack. Hell Ziggy did get a photo of me above getting a song sparrow out of the nets--easy cheesy. Alas, I was an over achiever with that bird, for I not only got it out of the nets swiftly, but accidentally let it go before we had a chance to put a band on it. Ah well, easy come, easy go.

While I was working on a chickadee, I could hear that someone else was trying to get a woodpecker out of the nets. Some can be quite squeaky and vocal when you are getting them out. I wasn't sure of the species, but could tell by tone that is was a woodpecker. I was surprised when they walked in with a young yellow-bellied sapsucker (above)! We really haven't seen them around Carpenter this summer, so I imagine that this is a young bird leaving its nesting territory--kind of like a kid leaving the house at about 18 years old and living on its own. Here's what the adult looks like. It's a pretty woodpecker.

It was challenging to try and get a photo, it kept flapping and squealing. I was curious to see if any hawks would come in. I've heard that sometimes playing a "wounded woodpecker" call and bring in hawks, foxes, coyotes, and mink.

We also got in a TON of catbirds. I think they young are finally leaving the nest and we may also be getting a few moving out of territories and pondering migration. I laughed when I was looking over the photos, my shot of one of the catbirds looks rather petulant.

Hell Ziggy's on the other hand looks down right artistic (and completely in focus). I've been hearing lots of reports of catbirds eating grape jelly (and robins too). Though it is possible that these species will regularly come in for grape jelly, I wonder if the increase in reports to me has to do with the dry conditions in Minnesota or more people taking notice?

Here's a photo Hell Ziggy got of Hasty Brook releasing a goldfinch. It almost looks like she's doing the flourish at the end of a magic trick. Hasty also got to release a catbird and appeared to have a magical experience.

Hell Ziggy on the other hand wanted to go for a more hard core, if not masochistic experience of holding a cardinal...

I got a shot of it, pre-crunch. Now, that's what I call a nail biter! Har har. She took it like a trooper though, and was proud of her blood blister from the cantankerous cardinal bill.

Afterwards, we headed out for lunch and I got some much needed fun conversation. Remember, you too could be having this kind of fun, so stop out at Carpenter sometime.

A Milestone For Me

And yet another grasshopper sparrow, they are everywhere I go, I can't escape them. I've seen them before, but not like this summer. I don't know if I'm just paying more attention or if we are having a bumper crop of grasshopper sparrows...or if aliens from some distant planet are trying to send me a message about saving the planet via grasshopper sparrow (although, that would seem to me to be an unreliable messenger).

You can tell this press release about Cape May Bird Observatory's new website was sent by a hardcore birder:
"Since you all have blogs and/or have close connections to Cape May I thought you might like to take a look at the site..... and in the event that you might be looking for something to write about given the slow nature of the summer......."

Slow nature of summer? Not in my neck of the woods! There's always some birding happening (and now bees--and some new caterpillar madness had started which I'll be talking about soon). Oh, how my grasshoppery ways have caught up to me this last week--sheesh. Here it is Monday, and I have bloggin' left over from last Friday.

So, Friday at Carpenter was a first for me--banding a tiny bird. Usually, at Carpenter, I'm happy to lurk and watch the pros but the bands swiftly on the birds. I enjoy trying to get the birds out of the net and bringing them in, but I always felt my place at the table was to just promote all the cool things that they do. I'm used to banding large birds, but not the tiny ones, so I have avoided actually pacing a band on a bird. Friday that changed. There have been offers before, but every time I always answer, "Oh, let's wait for a cowbird, let me practice on a cowbird, not a chickadee or goldfinch."

Friday, Jen Veith, the Development Director and experienced bander would not take no for an answer and had me band my first tiny bird--a house wren--man oh man, talk about a really tiny bird to band! Larry took a photo of this momentous occasion (above photo). It all happened so fast, and I was so freaked about not breaking one of those tiny wings, or legs that I barely remember it.

Up next was a house finch. Larry helped supervise the banding of that bird. You will note that we are doing these outside. Jen recommended that the first few times I band birds outside, that way, if I accidentally let one go, it won't risk injury by hitting walls and windows indoors. I was much more comfortable putting the band on this one.

Here I am taking the wing cord--fancy talk for measuring the wing. This house finch was a hatch year bird (hatched this year) and we couldn't tell if it was male or female. I measured the wings, all went well and the bird flew away.

Since many of the birds I have banded (pelicans, hawks) it's still hard for me to get the songbird bander's grip down: holding the bird in my left hand with it's back to my palm, it's head between my index and middle fingers, also holding it's chest. With my small hands, the finch and wren fit easily in my hand...

Then came a much larger hairy woodpecker--not so easy to hold in one hand--good grief, how will I ever hold a blue jay in one hand? This bird we could tell was female and were able to determine her age by her eye color (brown to grayish brown indicates that this bird was hatched either last year or this year). She also had a brood patch for incubating eggs and chicks, which she wouldn't have if she hatched this year, so that means she is a second year bird--she was hatched last year.

In between teaching me how to band, Larry got to band an eastern phoebe. I took a picture with his new Sony digital camera--it's got a pretty good macro feature--look at that feather detail. While we were taking this photo, the phoebe flapped a few times, and each time we heard a rapid clicking noise--phoebe's snap their bill when agitated--just like owls do! I never knew they did that. Of course, I've never had the opportunity to make a phoebe angry.

After banding, Jen and I explored the prairie area at Carpenter--loaded with grasshopper sparrows (another one above) and sedge wrens. Jen and I came upon a family of grasshopper sparrows, and the young were just learning to fly. It was a hoot to watch their labored flights around us and then the oh so awkward landing on what looked like a sturdy perch but turned out to be a wobbly prairie flower. About as graceful as a girl in her first pair of high heels.

There was also a pair of eastern meadowlarks scolding us, we must have been too close to their nests. It would be fun sometime to move the banding operation out to the prairie and get some bands on the birds out here.

Banding Young Raptors

A question came up in the previous entry about banding young raptors, do we worry about being bit and do we band the adults (and if so, how do you get the adults)?

Let's talk about handling raptors: If you have ever noticed from my fall hawk banding photos, we always are holding the hawks and falcons by the feet. It's the same with the young osprey, note Reier in the above photo. It looks like he is cuddling the bird, but he's keeping the feet safely away from his body and since the bird is pressed to his body, that prevents it from flapping around.

We're not really worried about the the hooked beak. The feet on raptors are the business end of the bird--their powerful toes are what separates them from other predatory birds--they grab and kill with their toes. So, when a raptor (eagle, hawk, owl, falcon, kite) feel threatened, their instinct is to always defend or attach with their toes and sharp talons. The beak is a last resort, it's too close to their eyes, and eyes are so crucial to their hunting ability that they don't want to risk putting them near danger.

In the last few years, researchers have also been taking blood samples from the birds. This could be useful for future DNA studies--especially if the populations fall low again and a reintroduction is necessary. Again, in the above photo, note how Amber is holding the young osprey's feet, and has her other hand over the bird's chest to hold it in place while mark takes its blood. Osprey are about five weeks old when we band them, they have learned to stand up and walk a little, but their wing muscles are weak. They also haven't figured out quite what their feet are for. As we are holding them, sometimes they will weakly and slowly make grabs with their toes, but they aren't nearly as swift and as strong as the adults.

Even when its time to put the bands on the legs, one person needs to hold the large chick while another places the band on the legs. Above, Amber holds the bird and feet steady as Mark places the band on the young osprey. Already, osprey banding is a two person job. However, that's just putting the bands on--getting the chicks out of the nest is another matter altogether. You either need...

...a cherry picker to donate their time and truck to go up and retrieve the chicks and put them back. Or you will need...

...a professional tree climber to donate their time and skills to go up and retrieve the chicks. It's a group effort to band osprey--at least two to three people are needed. Note that the climber in the above photo is also having to climb past a slick metal raccoon baffle to to get to the top.

As to the adults, they don't band them anymore in Minnesota. They used to do that when they first started the reintroduction program in the Twin Cities, but I've never observed it. To my understanding, it's not easy. It's not like other raptors where you can put out a bait pigeon and some mist nests--osprey only eat fresh (live) fish. From what I understand, they would take one of the education eagles from The Raptor Center and perch it out near the osprey nest. The adult osprey would fly in to chase off the eagle and either get tangled in nets surrounding the eagle, or some other type of trap. I remember a few times that adult osprey were brought in to TRC from banding because after they trapped it, they found fish hooks in their talons and were able to remove them and return the adults to the nest that day.

And for those curious, no education eagles or wild osprey were hurt or got hold of each other during the banding process.

Now, on to get check the the doin's a transpirin' out at the Kitty hive.

Osprey Banding

I don't know how many of you readers have been following the Zickefoose Blog about blogging styles: as a blogger, are you an ant (writing posts ahead of time and having a store of well thought out, well written, typo free entries) or are you a grasshopper (posting as the muse strikes you, never bothering to have a larder of entries)? If you haven't been able to catch on by my typos, I am very much a grasshopper. I would say that for the most part, that works for me. However this week, the blogging has been a struggle. Nor for lack of inspiration--but lack of time and alertness to do many posts. I have a back log of entries.

Now, on to Thursday's osprey banding:

My friends, Amber and Reier picked me up Thursday morning for some osprey banding with Mark Martell. We stopped at four different nests and had some interesting discoveries.

Nest 1: only one chick to band (mark did two nests on Sunday and each had three chicks) and the adult female had a transmitter on her back--she's from Milwaukee. Can you see the chick in the nest in this photo? When the osprey parents call the warning, the chicks go flat like a pancake, this only shows their brown feathers and hides the white feathers. To a passing aerial predator, the nest would look empty.

Nest 2: three chicks, one died as soon as it was taken out of the nest--very similar to what happened in 2005. The necropsy of the 2005 chick showed that it was severely weakened from a liver problem and that it died from cardiac arrest. The stress of being taken from the nest killed it, but had it been healthy to begin with it, then it would have survived the banding. The problem that the chick had would have killed it either before it left the nest or not soon after. I have a feeling, the necropsy for this bird will show that they same thing happened. Bummer.

Nest 3: Two healthy chicks. Although, besides just the pair of adults screaming at us as we banded, a third flew over and joined in the screaming and yelling. You should be able to see three birds in the above photo, flying in the sky.

Nest 4: Empty. What was interesting about this nest was that chicks were observed in the nest this past Sunday but a mere four days later they were gone. It was way too soon for them to have left the nest and even still, there should have been some osprey activity and it was dead quiet. A new eagle nest was built withing half mile of the osprey nest and Mark speculated that the eagles at the chicks sometime between Sunday and Thursday (guess the pancake defense didn't work so well that time). Talk about getting two birds with one stone (har har)--they get to juicy birds as well as cut back some of the competition for fish in the lake.

Sometimes great horned owls will take osprey chicks, but they aren't strong enough to carry the body away and eat it right in the nest. An eagle, is much larger and can easily carry an osprey chick. The lack of feathers and body parts in the nest points the finger to the eagle.

For me, the best part of the day was at the Lake Josephine nest. There were some kids who came to watch the banding and while this bird waited its turn to be banded, I let them touch it and even better--smell it. Since osprey only eat fish, they have a very distinct aroma. They also became our helpers, holding the bands and other equipment before we put them on the birds. They did a good job. Perhaps future naturalists?

And, because I feel like everywhere I go, I'm finding grasshopper sparrows, I'll include the above photo. This bird was near one of the osprey nests, perched on top of a sapling covered with a plastic tube (to keep deer from chewing it) and then covered with netting on top (to keep bluebirds from going into the tube looking for nest cavities and getting stuck). It tried not to move, hoping I wouldn't notice it just sitting there with some incredibly incriminating billful of food, on its way to feed a nest of hungry chicks. I was more entranced by the insect that whipped around in the tiny bill. I wonder what it was?

I'm Trying

I keep trying to do a blog entry about osprey banding today, but I keep finding ticks. I've lost count of how many I have found crawling on me and I'm not sure what's more disturbing: the number of ticks I keep finding or the fact that I've been out of a tick area for over six hours and I'm still finding them. Why are they just crawling on me, why aren't they latched on? Am I not to their taste or is something wrong my blood?

What does it say when you are rejected by ticks?

For Teageeare

Who tells me that I don't put enough Kabuki in the blog:
Here is my cranky little cockatiel, eyeing my inbox, hoping I will not notice if he pulls out and chews some paper. He and Cinnamon are about to go an a small adventure. We're going to dog sit for the next few days and we're bringing the pets with us.

I can't believe blogging escaped from me for a couple of days--it turned much busier here than I had anticipated. Next weekend should be about the same. I took Cinnamon with me to Carpenter Nature Center on Friday. I got an email a few weeks ago from some blog readers who said they might join us for banding. They asked if Cinnamon would be there and originally I had said no, but Thursday night and Friday morning, she was doing all those things that say, "Hey, mom, I need some stimulation." ie - digging in her litter box and sneaking into the kitchen. So, on went her leash and she went with me to Carpenter and found a whole slew of new things to disapprove of.

Even though we can still get her to put on the leash and harness without too much of a fuss doesn't mean she tries to chew and whip it off when she thinks I'm not looking.

We're getting in quite a few of the summer residence. Above is a male robin we have had in the nets twice this summer. You can tell he is male by the dark head and the darker rusty breast. Boy, he really looks unhappy in this photo.

We also got in this hairy woodpecker. Notice anything strange about him? Check out his red patch--it's on the front of his head and not the back--a way you can tell if the bird just hatched this year when it is at your feeder.

Cinnamon was not as impressed with all the banding going on and was way more interested in exploring all the prairie grasses. Just by hopping in a few feet, she would completely disappear.

Apart from the leash, the only other way you could tell she was in there was by watching a tall piece of grass waver for a moment and then fall over as she had chewed its stalk. She was almost on sensory overload with the abundance of chewables at her feet.

To a blade of grass, she's kind of a scary looking monster. Afterwards, she kept me company as i scouted for a field trip that I was leading on Saturday. Which I will blog about later tonight. Right now, I have to go out and check on the bee situation...have I prevented a swarm...will the Olga hive be ready for a queen excluder...what wonderful bee adventures will I encounter this week?
