Digiscoping Workshop & Tern Rescue

One of the reasons I was at the Great Salt Lake Bird Festival in Utah was to conduct a digiscoping workshop for Swarovski Optik.  I really enjoy doing these types of workshops, we start with a basic how to and then we go out someplace birdy and take photos.  They are not trips about getting a ton of birds on the list, but more going someplace with a lot of slow moving birds and practice taking photos--you really get to spend some time watching a bird.  Sometimes I do this with perched out education birds or at a nature center with bird feeders.  In Utah, we went to Kaysville Ponds a small park with lots of cool birds like the above pelicans.  It's an urban and well used park.  There were several families making use of the ponds' ample fishing resources and walking trails, it was great to see so many kids enjoying the outdoors on a Saturday morning.

A really cool bird for me was the western grebe.  We have them in western Minnesota but that's a trek, so it was a treat to see them in this urban pond so close and spend time taking photos of the birds.  Although, I generally end up loaning out my scope during these trips.  I think many people get a digiscoping set up, take 12 photos that are crap and then are hesitant to use the equipment.  When I give someone my scope, I sometimes tell them, "I don't want it back until you take at least 250 photos of that bird."  The grebes were so close and so mellow, they were great to practice on.  And if you end up with 248 blurry photos, they are easy enough to delete.

There were also a ton of yellow-headed blackbirds perched in the open to photograph.  People got to practice with close up birds and birds further away (and learn the heartbreak of what heat shimmer will do on your seemingly in focus photos).

I did use this as an opportunity to practice some Blackberry scoping--holding my Blackberry phone to my scope and taking photos of birds.  The photos are not high quality, but they do have use.  You could document a rare bird and text the photo to your local state records committee, text the photo of a bird that your friend has not seen, sent it to Twitter or use your camera phone as a back up to document a rare bird if you camera batteries die or you left your camera back in the car.  It's not easy because you have to hand hold the phone to the scope's eyepiece but practicing on every day birds will help you be ready should a rare bird show up.

Here's a Blackberry shot of our class, it was a fun group and again, I love being out in Utah where you are surrounded by snow capped mountains on a sunny day.  The temps were mild and the wind was low--a perfect day for digiscoping.  I brought some different camera adaptors for scopes for folks to try and few people brought their own adaptors andwe had a good compare and contrast of what works easily and what does not.

As we were taking photos, I noticed a Forster's tern frantically calling.  I looked over as did friend and fellow field trip participant Suzy and noticed a Forster's tern in the water while another flew and called loudly overhead.  Suzy noted that the flighted bird had a fish and attempted to offer it to the bird in the water.  Looking through the scope, the bird int he water had its tail at an odd angle and could not pull its wing.  The tern tried to flap out of the water but could not flap well at all.  "Great," I thought, "a wounded bird at our workshop."  Suzy hoped that it was an adult feeding a young, but both were in adult plumage.  I wondered if there was any way to reach the wounded tern but it was far out in the water.  I continued with the workshop with half an eye on the tern, when I noticed the flighted tern dive bombing a man on shore.  I limped over to investigate (I'm still a little unsteady on my knee, but it is healing up a little every day).

I found a man with a fishing pole reeling in the tern from the water while the other tern angrily dove at him while screaming loudly.  He took the tern out of the water and had some clippers.  He was trying to clip the line around the bird but the tern was snapping its beak at him and he was afraid to touch it.  I hobbled over and asked, "Can I give you a hand?"

"Yes, please!"

I picked the water logged tern up out of the water--how strange to put a tern in the bander's grip, they seem more like a piece of origami than bird.  He swiftly snipped off the fishing line and fortunately the hook was not in her.  I did a quick feel for broken bones but couldn't feel anything amiss.  The formerly tangled tern's feathers looked too waterlogged to fly.  I made a split second decision to let it go back in the water rather than spend the day looking for a rehab center with might cause more stress, especially if the tern wasn't injured, only wet and tired.  I opened my hands for her to fly but the tern couldn't get airborne and went right back in the water.  I figured that it would be far better for the tern to swim to a quiet spot, dry off and preen its feathers.  The bird was mostly likely exhausted from the struggle to get away from the tangled line.

The man with the pole kept apologizing.  He was there with his son to go fishing and when he cast his line, the tern flew into it and got tangled, it was a one in a million shot.  He watched the tern swim away slowly, "Oh no, I'm so sorry."

I looked at him and his little boy and said, "You did your best to help the bird, I'm sure it just needs to dry off, it's featers were soaked and it wouldn't be able to fly."

"She's probably exhausted too," he said.  I agreed.

"I watched before I cast," he said mornfully, "I always watch for birds.  And when I swung, there she was!"

As the bird swam away, some gulls flew over low to investigate (assessing if they could eat it, I'm sure) and then a pelican swam right for it and opened it's mouth.  "No," I shouted, "not today pelican!"

And that was enough to distract it and the tern paddled further away.  I'm all for watching cool and gross natural history moments, but this man and his son seemed traumatized enough as it was and didn't need to see the pelican eat the tern (that's not a pretty way to go, I think I'd rather be eating by a great horned owl).  And if you don't know what I'm talking about--those big birds are opportunists and there are videos of pelicans eating pigeons in parks.  A Forster's tern is about pigeon sized.

The tern attempted to fly off the water a few more times and each time it got closer to being airborne.  Eventually, it disappeared into some reeds on an island where I'm sure it preened and dried out.  The man gave up his fishing for the morning, he genuinely felt bad about what happened even though it was just one of those things.  I'm glad he took the time to help the bird and I hope he doesn't give up fishing for good.

When the pelicans weren't trying to eat terns, they made excellent digiscoping subjects!  It was interesting to note the various sizes of horns on the upper bill.  The above bird has a small one.

Check out this bad boy--his horn is HUGE and looks quite impressive in his full on display!  No one knows for sure why males get this epidermal plate on the top mandible, but presumably it has something to do with a mating display to female pelicans.  It falls off during the summer after the breeding season.  I have a couple from my pelican banding days.  They look like nasty toenails.

Since pelicans don't sing to attract a female, the put on these quiet, yet showy displays on the water.  It almost looks a little passive aggressive, the male silently lifting his wings, puffing his feathers and crooking his neck while showing his horn and a female or two will quietly swim by and quietly take note of this display...and then keep going.  It's very Minnesotan.

We had a few warblers and even an oriole (the above Bullock's oriole) to round out the rest of our field trip.  Participants seemed to have a good time and learn a few tricks--like try out video on your little point and shoot cameras.  One man even got video of a coot feeding it's baby.  All in all it was a beautiful morning and it's always fun when your group can do a good deed while on birding trip--like helping out a tangled tern.

Bird Nesting Material

This is a post I typed up on May 3 but for some reason it never published.  Here it is:

On Saturday I noticed a tufted titmouse gathering some of Cabal's hair in the driveway.  The bird was furiously grabbing hair as if hoping to avoid attention.  It reminded me of when I was kid growing up in Indiana and watching titmice steal tufts of fur off of my pet husky when she was napping outside.  Dog hair (or most pet fur) is great to let loose outside this time of year for bird nesting material.

If you are going to put out nesting material for birds, look for natural fibers to put out.  If you set out yarn or string, make sure that it is no longer than 6 inches.  Birds can use long string, but there's a risk with long string for birds to get it caught on a branch and get tangled in it.

I've read conflicting information on dryer lint--some say it's fine, others say it's no good.  Here are my thoughts:  if there's no consensus, they why risk it?  I don't use dryer lint.  Plus, I'm not sure how much detergent and fabric softener residue is on dryer lint and if that would be a good or bad thing for recently hatched chicks.  Stick to natural fibers and pet fur.

Unexpected Weasel Encounter In Utah

Yesterday I had some time to kill before my flight back to Minneapolis from Utah.  I stopped for a wee bit at the Great Salt Lake Nature Center in Farmington to enjoy a final few moments of yellow-headed blackbirds.  As I walked down the gravel road, I noticed a mammal hopping across the path.  I didn't quite recognize the long shape and assumed it to be some sort of ground squirrel.  However, I saw the animal zip across the road again and this time instantly recognized it as a weasel.

The weasel paused for a moment on a rock through some reeds and got a really craptastic photo but was excited because it looked as though the weasel had some prey in its mouth--how awesome is that?  It paused long enough for me to get this shot then disappeared into the vegetation.

But a few seconds later, I was surprised to see the weasel come out on the road and it started to hop along in my direction.  I'm not sure if "hop" is the right word for weasel travel.  It looks more like the critter's body is part of a Slinky curving up and down.

The weasel paused, it was far too close for me to digiscope so I took photos with the camera old school.

And the weasel just kept coming closer!  I tried to get my scope into the shot to show how close the mammal was to me.  I was perplexed and mildly concerned that it was coming so close--actually heading right for me.  I wasn't flailing my arms, I stood still, but it would have heard my camera clicks and that should have been enough to want to give a human a wide berth.  Weasels are carnivores and are known to go for prey larger than they are, but as short as I am, I doubt a weasel would consider me prey worthy (a mountain lion would, but surely not a little weasel).

Then the weasel bounded up next to my right side, it wasn't even a foot away from my shoes and paused.  It suddenly dawned on me that I had just seen the weasel moments ago running back and forth on this trek with something in its mouth.  I know they are formidable predators and that they have an instinct to kill food when it's abundant and store if for later, but still--getting several small mice at once?  Perhaps this weasel was not carrying prey, perhaps this was a female transferring her young from one den to another?  I've read that weasels will move their den location and transfer the young if it is disturbed.

And then she dashed past me.  Based on the length of her tail, I wondered if she was a long-tailed weasel or an ermine.  Consulting my Peterson Mammals of North America revealed that in Utah, she would be a long-tailed weasel.

After she made it past me, she booked it to the other side of the road and down into a shrub.  After sixty seconds, she reappeared and bounded past me again.  She must have had another kit to retrieve from the old den.  I tried to set myself up to see if I could get shots of her through my scope on her return.

Check it out, it's hover weasel!  Sure enough, she returned with another kit in her mouth and bounded right for me.  Note how her long tail sticks straight up has she runs.

With my scope pointed at her this time, rather than just my camera, she stopped much further away to assess the situation.  Since weasels are a top predator (for their size), they know that being stared at is not a good sign.  If they stare at something, they are generally trying to determine how they can kill it and eat it.  Having an 80mm objective lens pointed right at a her probably made her a bit more hesitant to run past me with one of her young in her mouth.

This time, she crossed the street--look at the tiny toes and skinny tail of her offspring--cute!

She continued on her journey and I continued down the trail.  Who knows how many more young she had to transfer.  Weasels can have 4 - 8 kits so if she had a large nest, she had her work cut out for her and didn't need me to distract her from the task at hand (or paw in her case).  This was a new mammal for me.  I've seen ermine, least weasel and mink, but this is my first long-tailed weasel.

Back In Utah

If I could have a love affair with scenery, I think Utah would be a top contender.  This is my third trip to this state and every time I arrive I always think, "I do not have enough time to explore everything I want to explore."

The sky is a constant swirl of colors with snow capped mountains surrounding you.  When I tweaked my knee last Saturday, I was wondering how I would fare but so far so good.  I put in a wheel chair request with Delta and the wheeled me to my gate, they gave me a better seat to let my leg stay extended, wheeled me to baggage claim, grabbed my bags and wheeled me to my rental car.  I called the hotel ahead of time (which interestingly does not have any of the expected literature in the room, but a couple of books by L. Ron Hubbard and a Scientology brochure) and they gave me a room on the ground floor, near a door and helped me with my heavier luggage (and some of those Swarovski cases are not light).  My knee is getting better every day, although, I still can't quite bend it the way I used to yet, but at least the swelling has reduced considerably.

I had some time in the afternoon and I couldn't get in to the Salt Lake Bird Fest show area to set up my booth, so I went to do some birding.  What better place to revisit than Antelope Island?  I can easily drive around to take photos (I had force myself to not go hiking all over the trails, but better safe than sorry).

Antelope island lives up to it's name.  This was not digiscoped but taken out the passenger window of my rental car.  The antelope weren't so much playing as trying to craze and loped away as if to say, "Yeah, Midwesterner, I'm special to you, but I do this every day, move along."

There were quite a few black-bellied plovers on the road out towards the island--it's so fun to see them in breeding plumage.  We get them in Minnesota but not when they look all snazzy like this.  When I've seen them, it's been cold, windy and they are gray with black "armpits."  But in breeding plumage, they are down right dapper.  Saturday morning I'm going to do a digiscoping workshop and we are going to have such a great time!  Birds here are so accommodating.

One thing I did forget was the noseeums.  I left my bug spray back at the hotel and every time I opened my window or stepped out, they swarmed.  The clouds were so nasty, they went into every opening--ears, nose, mouth--ick.  My scalp was on fire with bites until I had the sense to put my hood of my hoodie up and then drive away from the swarms.  Still got some great shots.  Below is a western meadowlark singing.  You can hear me walk away from the camera taking the video (trying to avoid a swarm of noseeums), you'll hear one buzz the microphone and then you'll see the western meadowlark rub his face as if to scratch an itch:

Love that song!

Tawny Owl With Mandarin Ducklings

Check out this story and video from the BBC about a tawny owl (which nests in a box they way our screech owls do here in the US).  The box is fitted with a nest cam and watchers were expecting owlets.  However, they were surprised to find mandarin ducklings running around and all over the owl in the box (kind of like a screech owl with wood duck ducklings running around all over). The article paints a prettier picture by saying that the ducklings will hop out but who knows if they will without a female duck below to call at them.  Since these ducks are precocial like wood ducks--meaning they are fully mobile after hatching and follow their parents while picking up food on their own they do not need to be fed by the adults.  Confusion will be had by all if the male returns with a mouse and the female attempts to feed the ducklings who will not beg for it.

A few days before hatching, the ducklings pip from inside the egg, the hen calls back and the imprinting process begins.  If these ducklings heard anything, it's the coos of the tawny owl--will they stay in the box if the owl does?  If hunger forces the ducklings to hop out, will they be able to hook up with another brood?  Will they be able to do it before a fox...or the male tawny owl catches them?  Who can say, but it sounds like that pond had some egg dumping going on and more duck and owl boxes need to go up.

This is similar to the osprey with the Canada goose gosling incident we had happen in the western suburbs of the Twin Cities a few years ago.

Kestrel Takes Stage At Target Field

I'm not much of a baseball fan (being from Indiana, I'm pre-programmed to enjoy basketball, specifically Big 10 basketball).  However, the new Minnesota Twins stadium has been such a focus of the news, I know far more about it just from osmosis via radio, tv and social media updates. The big news early on was a red-tailed hawk pair that was reportedly nesting behind the new scoreboard at Target Field.  I thought it would be interesting to do a story on it and maybe get some photos but Target Field was not really interested in taking calls on the nest.  I called the Minnesota DNR to find out if they had any information or photos of the nest and was told that the nest had been removed by workers at Target Field.  Since the nest was first reported in March (which is when red-tail lay eggs in Minnesota) and it was removed after that, I wondered if there were eggs in the nest when it was removed, making the removal a violation of the Migratory Bird Treaty.  It didn't sound like the issue was going to be pursued and if there was concern over the nest, better to remove it early while the red-tails have a chance to renest (like they would if a wind storm blew it down).  Also, it was good that the nest was removed early before there were chicks older, the adults more aggressive in defending their territory and we wouldn't have another mess like last year when a DNR officer shot some nesting broad-winged hawks in the south suburbs.

However, another raptor is filling the void at Target Field--Kirby the Kestrel:

Here is the small male kestrel captured on the jumbotron at Target Field and is entertaining fans with the falcon's awesome ability to grab insects in the air with its toes.  This is an American Kestrel and it's been fun to watch news stations like WCCO report on the small falcon but incorrectly use a photo of the Eurasion kestrel.  These birds are cavity nesters, usually using old woodpecker holes made by flickers, red-bellied woodpeckers or even pileated woodpeckers to for nesting.  They will also use large bird houses like wood duck boxes or you can purchase kestrel boxes from your local bird store.  I've seen them nesting in the Uptown area of Minneapolis in old homes with holes leading into an attic or duct work.  I'm not sure there are any cavities for the bird to nest in at Target Field, perhaps there are some old trees nearby for the male to lay claim to and he will attract a female...and hopefully the Target Field employees won't remove a kestrel nest and embrace it as part of the fun of an outdoor baseball game.

This particular bird seems to have quite the following.  According to this story by the Star Tribune there was a "Name the Kestrel Contest" and he has been dubbed Kirby the Kestrel, in honor of the Kirby Puckett.  He's such a hot item that someone started a Twitter Account for Kirby...too bad it's as TargetFieldHawk and not TargetFieldFalcon but I'm happy people are noticing birds even if they are mixing up their species a bit.

Here's a Youtube Video of Kirby in Action:

If you are catching a Twins game at Target Field, watch for Kirby at the right field foul pole.

Cross Section Of Breeding Birds & Migration

Twice a year I have some bird banding friends come out to Mr. Neil's place to band the birds around the yard--once in spring and once in fall.  On Saturday my buddies Roger (aka MNBirdNerd) and Amber (aka AvianImages) set up mists nets to collect data and got a GREAT cross section of spring bird activity from migration to breeding.  I hoped we would get a ton of cool information since I've noticed birds like the above red-bellied woodpecker coming and flying away with large beakfuls of suet--do they have young in the nest?

They did get in quite a few woodpeckers.  Here's a hairy woodpecker male (note the little bit of red on the head).  Roger gave him a blow and revealed a brood patch.  Both males and females incubate so both would need a bare patch of skin swollen with blood vessels to keep the eggs nice and warm during incubation.  I went to see what Cornell Lab of Ornithology had to say specifically about hairy woodpecker and in the breeding section that mentions, "onset of broodiness" and that "incubation begins in earnest with laying of last egg, but male roosts in nest cavity and de facto incubation may begin with pen-ultimate egg, thus accounting for hatching often occurring over a 2 day period and for some of the size differences noted in nestlings."

I love that someone other than my husband uses the word "pen-ultimate"to say that because the male sleeps in the nest cavity at night, incubation could start when the second to last egg is laid by the female.

For the past few springs we've had a couple of pine warblers come in to the feeders when the weather is cold and insects are not out in full force.  Warblers generally are not feeder birds, this brightly colored group of birds primarily eats insects--except for the pine warbler.  During a cold, wet spell like we are having right now in the Twin Cities you can find orioles, catbirds, yellow-rumped warblers, scarlet tanagers coming to suet feeders as an alternate source of protein.  Above is a pine warbler eating some no-melt peanut suet.  What makes the pine warbler a little different from other warblers is that they are known to eat seeds and sometimes, I see pine warblers eating sunflower seeds out of the shell as well as suet.

I think the rather disgruntled look on the face of this male pine warbler about says it all.  While we banded this bird, a second pine warbler came to the feeder.  It looked more like the bird in the photo above this--either a female or second year male.  I suspect that pine warblers are nesting nearby  since they sing well into June but it's hard to say since they quit coming to feeders so I don't see them feeding young (and I've yet to find the nest).

There was a huge brush pile that was chock full of sparrows and they set the nets near that and got a few white-throated sparrows.  When Roger blew on their breasts, he was watching for fat rather than brood patches.  These sparrows are still heading north and birds that showed yellow globs of fat just under their skin were loading up to travel further north.

The number of rose-breasted grosbeaks at the feeders have been increasing exponentially this week.  About seven days earlier, I heard one, then three days later, three males were at the feeder and by our banding day, I would say that we had five males jockeying for position on the feeder--and then one lone female.  Males typically arrive first to set up territory, so it was fun to see that in action.  We determined this bird was hatched last year, he had a few brown patches of juvenile plumage that had not molted out yet--not unlike some of the young males I saw in Panama this past February.  I wondered if the grosbeaks who arrived early on territory in sleet and cold temps and think, "I left Central America for this?"

Keep your eyes open at the feeders and in the woods.  Migration is in full swing, we have quite a few birds just flying and a few more who have yet to arrive.  With this wet weather, some birds will look for fast food like  bird feeders and you might be surprised by what you find.

A Birding Injury!

Ah, Saturday started out so promising!  We had spring bird banding planned at Mr. Neil's, I found out that my nephew has an exhibit at the Louvre (yeah, baby, that Louvre and it's part of an app that's really cool called Augmented Reality Wallpaper), Non Birding Bill was frying up some maple bacon to get the banding started off right--it was all so innocent then. We had the usual Minnesota back hand weather-wise.  A snow free March and April meant that the first weekend in May was going to be cold, cloudy and involve snow and sleet.  Because of the wet and an mud on the trails, I put on a pair of spare Wellingtons at the house--the boots were a couple sizes too big but I compensated with really thick socks.  However, at one point during a net check, my foot went one way, my right knee the other which was followed by my collapse and intense pain.  It felt very similar to when I dislocated my knee as a teenager.  But I was able to stand up and limp--which I was not able to do when I dislocated my knee.

NBB drove me to Urgent Care where ironically I was banded, weighed and measured (and had a few unpleasant things done to my knee).  NBB said, "Ha!  Now you know what it's like for the birds when you band them."  They made a note of higher blood pressure and assured me that was normal for a painful knee injury.  The spike in pressure wasn't about the pain but more like, "Holy Crap, I fly to Utah on Thursday for the Great Salt Lake Bird Festival on top of how much I love gallavanting in the woods for warblers in spring on top of my national park service duties.  I can't be injured now!"

Fortunately, it appears to only be a sprain and not too severe of an injury and I'm supposed to stay off it and ice it for as long as possible.  NBB is doing a great job of forcing me to take it easy.  I was actually back to the banding in about an hour and didn't miss too much.  Lorraine got the above photo of me taking photos of Amber and Roger removing a rose-breasted grosbeak and downy woodpecker from the nets.

Here is a none too pleased rose-breasted grosbeak.

The great thing about the modern age is that I put in a call to my hotel in Utah securing a ground floor room, made arrangements to get some mobility assistance in the airport and gave the festival a heads up to my limited mobility.  But on the upside, I'm doing a digiscoping workshop, Birds and Beers and I'm Friday night's guest speaker--all of those aren't too strenuous.

I'm excited about speaking.  The festival keynote had to step down at the last minute for health reasons, so Bill Fennimore who was Friday's speaker is filling in for her on Saturday and I'm filling in for him on Friday night.  I'm going to do my Kazakhstan Program: An Adventure in Birds and Bathrooms.  Utah is one of my favorite birding states, I'm so grateful that my injury may slow me down but not stop me from enjoying this beautiful area.

In the meantime, this business of being forced to sit in one spot for several hours will be a good opportunity to type up some birding app reviews and a book review.  I'm reading an AMAZING feather book--best bird book to come out this year.

Cool Bee Installation Video

One of my favorite birders to follow on Twitter is Scott Fraser.  He's funny and has a hardcore programming job by day and a hobby farm by night.  He started beekeeping and he made a time lapse video showing his family installing their bees this spring.  It's interesting to watch because of the lack of bee suits the family wears--note how the kids are dressed.  Also, he installs his bees a little differently than I do--not that there's anything wrong with that.  Goodness knows that beekeepers never agree on the best way to do something (that and a genuine love of bees are the 2 most consistent things about beekeeping).
