Cruise Ships Potential Habitats For Burrowing Owls?

Probably not, but intrepid burrowing owl sure did try.

The above Florida Fish and Wildlife Conservation Commission is of a burrowing owl that tried to set up a territory mini-golf course on Royal Caribbean International's "Oasis of the Seas" last Saturday.  The ship was about to depart Port Everglades for the high seas when a crew member called the Florida Fish and Wildlife Conservation Commission regarding this unusual passenger.

FWC Lt. David Bingham and a Broward County Sheriff's Office deputy were able to safely remove the small owl from the golf course. Bingham released the owl in an open field in western Broward County.

"Never in all of my 25 years with the FWC have I seen anything like this, and I have responded to some strange calls," Bingham said. "I am very pleased the owl wasn't injured and that we could get it back to a normal habitat."

As a species of special concern, Florida burrowing owls, their burrows and their eggs are protected from harassment and/or disturbance by state law. Burrowing owls also are protected by the federal Migratory Bird Treaty Act.

"Burrowing owls need to be in open, treeless areas where they can dig their burrow," said FWC biologist Ricardo Zambrano. "The artificial turf on the ship's golf course resembles the fields they use for nesting in urban areas; however, it was obviously not suitable habitat for this owl."

One has to wonder how long this owl was there and what it might have been feeding on.  According to Cornell's Birds of North America Online, burrowing owls are "pportunistic feeders; primarily arthropods, small mammals, and birds; amphibians and reptiles also reported and may be important in Florida."

Goldfinches Still Nesting In Late September in MN

Jeff Gordon had a great quote today, "The very first Snow Geese just flew in. Eleven black and white nails in summer's coffin." Which was how I felt when I saw the first juncos creeping in to the Twin Cities last week.  I typically adore fall and I'm pro winter (what's the point of choosing to move to Minnesota and living here for over a decade if you don't like winter).  For whatever reason, I'm not emotionally prepared for fall this year.  It might be because I'm overbooked and can't enjoy fall hawk migration as much as I would like, but every sign of autumn I see from my local grocer carrying my favorite Maple Walnut Coffee to the massive amounts of Hen of the Woods popping up to the availability of my favorite Hubbard squash, I keep thinking in my little budgie brain, "STOP!"

Yesterday, I saw a bird flat that out refuse to accept fall:

I found goldfinch chicks--still in the nest being fed by an adult on September 21 in Minnesota!  American goldfinches are probably our latest nesting bird. They don't start nesting until July when fibers they need for nesting material are finally available.  Also, goldfinches are major seed eaters.  Many people think of chickadees and cardinals as seed eaters, but they eat quite a few insects and need those for their young--they can start nesting earlier.  But a goldfinch needs lots of seed available--seeds are such a large part of their diet that a brown-headed cowbird chick cannot survive in their nest.  So it makes sense that they have young later in the summer when more plants will have seeds available to feed to a whole new generation of goldfinches.

However, even this seemed late to me.  I emailed a friend who keeps track of these records at the Minnesota Ornithologists' Union and he said, "That is getting late. From the list of records I've compiled, the latest date of an active nest still with eggs is 30 September (Hennepin County 1894)."

I wondered if this was a goldfinch going for a second brood in a season or if the first nest failed and this is a late second attempt?  If the weather stays warm, these young finches still have time to hook up with a larger flock of goldfinches and if there is a good forage route, they may survive the winter.  Birds play the odds with nesting--they raise as many as possible either with a large brood or attempt more than one brood in a season to insure that at least one survives into the next breeding season.

Incidentally, this nest was right next to a highway bridge (Highway 77 to be exact).  So, if you ever wonder about birds and urban noise, some birds learn to adapt and choose to nest near highways.

Good luck little goldfinches.

A Plea To Birders

I posted this on Facebook and Twitter, but I'm going to add it here as well.  There was a segment on the Katie Couric news show about the Great Texas Birding Classic and while I think it's awesome that birders were in the news and equally awesome that most of those birders were wearing Swarovski.  However, I did see something troubling. Just watch 10 seconds of the video.

Birders (or bird watchers if you prefer), for the love of Pete, when a news camera is on you: DO NOT IMITATE BIRD CALLS.  No one wins when that happens.  I'm sure your black rail call is awesome and brings all the rails to the yard, but really, it will not help bring more people to the fold. I can't think of one non birding person who would see that and think, "Yes, that rocks, I don't know what birding is, but I'm going to do it right now!"

I think young kids will watch that and think, "Holy crap, is that the sort of people who are outside in the woods?  I'm staying in with my video games where it's safe."

I get asked to bird calls by the media and I refrain, it's easy to do.  Really, you can say, "no."  You can tell they think they will get the funny sideshow factor in their segment by asking you to do it and I've seen more than one reporter aghast at my refusal but then you see something in their eyes, perhaps something new--respect.  I kindly offer to do bird calls with my iPod Touch, but I refuse to do it with my lips (okay, maybe I've whistled the two note black-capped chickadee call, but that's it--I'll give you a pass on a chickadee--but no soras, no blackbirds, please for the sake of humanity, don't do a puffin).

So, please.  If we want to keep birding (according to Katie) the second most popular hobby, stop doing bird calls on tv and the news!

Thank you.

Migration, Carlos Avery and a Pub Quiz

Merlin's Rest put out the call for Guest Pub Quizzers and I'll be leading the Pub Quiz this Sunday, September 19 at 7:30 pm.  If you know me and the blog, you have an idea of what kinds of quesitons I'll ask, but I do promise that it will not all be bird related.  I'll have some cool prizes...perhaps even some honey from our hives for the winning team.

I keep trying to deny autumn this year and I can't.  I took this photo two days ago at Carlos Avery Wildlife Management Area.  One can't deny red oak leaves as a sure sign that it's getting colder and the days are getting shorter.  My denial was broken in full yesterday when we went on a canoe/kayak paddle in my park for work...it was a tad chilly on the river and my fingers had that dry skin ache that is exclusive to cold, dry air.  Sigh.  I did get one pleasant reminder of fall--Mr. Neil's housekeeper called to say that they found a 20# patch of Hen of the Woods in our usual patch--my favorite wild edible.  We will have some tasty soups and sauces with that fungus this winter!

Canada geese are on the move and I got word that my waterfowl surveys start soon--at the end of the month.  My route got expanded this year, but I'm also nervous.  I went on a ride along for this new extension last year and the amount of ducks and species mix is a lot to take in.  Will I be able to count them all?  We'll do our best but I feel this year's survey is of utmost importance.  When we do this again for the next few years?  Will those numbers change with the Gulf spill?  Despite "capping of the well" the spill is not over, there's still a ton of oil in the water, it's below the surface so you can't see it, but it's affecting the food supply.

Of large concern to me is the recent fish kill in Louisiana, Check out This Is Not A Road.  Disturbing amount of fish and also interesting that in this fish kill it's several species of fish.  I've seen fish kills--we get them along the Mississippi in spring and even on some of our lakes,  but it's usually one species of fish.  This huge fish kill in Louisiana is SEVERAL species and includes sting rays and a whale.  The government says that the oil spill is not the cause even though oil is clearly visible on the fish in close up shots.  They official report is depletion of oxygen...which happens this time of year and does cause fish kills but usually not this large and the depletion is caused by the dead zone in the Gulf (created by fertilizer pollution from farmers on the Mississippi River) and most likely exacerbated by the oil and more likely the chemical oil dispersent put in the Gulf).  There's a great report on the fish kill from the AP on YouTube and an explanation on New Scientist.  I think we'll see more problems.

Sorry for that tangent.  I'm not exactly sure what to do about the oil spill.  I want people to know that it's still a problem and that many birds (and other coastal creatures, not to mention people's jobs) are in peril, but I don't want this blog to become your daily downer.  Just promise me you won't buy into the idea that oil spill is over and we still have problems to solve, 'k?

Back to birds:

There's a feed plot at Carlos Avery and I chuckled at this goldfinch, it was eating the tassels.  I know finches are primarily seed eaters and I've recently learned that they eat all matter of plants, but I'm beginning to suspect that there's not a piece of vegetation they won't eat.  I do have to hand it to them as far as creativity.  You pheasants and your bobwhite go for the corn kernels, goldfinches go tassels.  Great way to avoid competition.

Warblers, like the above yellow-rumped warbler were flitting among the tassels too.  The appeared to be after tiny insects rather than the plants themselves.

All the grasses and shrubs along the road were alive with small birds.  If you could see their shadows rustling among the leaves, you could hear their contact chip notes.  A little pishing (for non birders, say the word "pish" only in a loud whisper) made some of them pop up to investigate the sound.  Above are some swamp sparrows (the one on the left looks like its still molting heavily).

I love swamp sparrows and they blend so well with the changing fall foliage.  I especially love it when see a sparrow head on, they look like cranky old mean with muttonchops.  I almost feel like this one should shouting in a wheezy voice, "Hey you, whipper snapper, quit that pishing racket!!"  As I was taking their photos, I could hear sandhill cranes calling in the distance and I noticed that they were flying above me:

I would guess that this is a family group of cranes.  Perhaps they were doing some laps, getting their wing muscles in shape and teaching the young birds the mysteries of finding a warm column of air spiraling up to glide in.  Those thermals save energy when on long journeys.

These cranes are far enough south that they have avoided the Minnesota sandhill crane hunt, but depending on their route, they will have to watch out for the hunts in Kansas and Texas as well.  Good luck, cranes.

MN Bun Fest–Meet Cinnamon

A little non birding news: Non Birding Bill, Cinnamon and I will be at Bun Fest tomorrow (Saturday) at 11am.  This is a rare public appearance of our dear rabbit in her old age.  We'll sign Disapproving Rabbits books, answer bun questions and encourage you to support this great rabbit foster organization.  If you have ever considered a rabbit as a pet, this is the perfect organization to learn about rabbit ownership and finding a rabbit that works for your family.

When The Minnesota Companion Rabbit Society asked me to bring Cinnamon I was hesitant, she's pushing 13 years old--that's geriatric in bunny lifespan.  Years ago, a tiny dog with a big book and calendar series was on KARE 11 the same day I was on answering bird questions.  I thought the animal was puppet, because it didn't move naturally.  When I finally realized that it was a "live animal" in the handler's lap, I could see the dog looked a little off, didn't seem to be able to stand on it's own, eyes not registering all that was going on around it, almost as if it looked it was either drugged like crazy or barely alive.  After I went home, I googled the dog and discovered at the time he was over 10 years old and I guessed that the owner had created this whole publishing series around him and couldn't get out of personal appearances no matter how old that dog was.

I never wanted to do that to Cinnamon--I never take her out unless she's "up for it".  She likes people--when I worked at the bird store, she was practically an employee--she was our store greeter.  Now, Cinnamon has her good and her sleepy days.  Some days she's her frisky self, albeit slower or she has days when she just wants to sleep.  She doesn't do speeding laps in the hallway anymore but shuffles around the apartment.  This week she has been feeling her Wheaties.  She actually tried to sneak into the kitchen--something she does when she wants you to play with her and as I type this, she's flipping around a spoon.  She loves canned pumpkin or squash and we usually give her a spoonful in the morning.   Sometimes when she's finished eating the pumpkin, she flips the spoon around--one day we found it wedged in on of the openings of her toddler gate--about a foot up...

So, she looks old, but she's feeling frisky and we made the decision yesterday to bring her out.  If you'd like to meet the original Disapproving Rabbit,  tomorrow is the day.

Speaking of Cinnamon, I love it when people tell me they have been inspired by Cinnamon and make art like this or the Disapproving Rabbit pumpkin or this portrait.  This week, Heidi Brenegan who works at Animal Emergency Clinic in Oakdale, MN made painting for the clinic's lobby of all the varieties of pets they work with and she made one of Cinnamon:

If you happen to be at that clinic, check out Heidi's original.  Thanks, Heidi, we're honored!

9-11 Memorial Tribute of Light Causes Major Problems for Migratory Birds

Sometimes, people with the best intentions get tripped up with the big picture.  September 11, 2001 was a dark day, a horrible day and some people are still suffering from it.  On every September 11th since 2001, the Municipal Art Society has shone two bright lights skyward from Manhattan's Financial District called Tribute of Light:

This is a photo from wiki common--that's a pretty bright light.  I've seen lights like this shoot up from buildings in Las Vegas and other countries and I've always wondered how that affects birds during migration. Especially someplace like New York which is part of a major migratory corridor.  If weather conditions are right and thousands of birds are migrating over that right on September 11...what would happen?

This year, we found out what would happen when more than 10,000 birds flew into the beams and got trapped and appeared to be unable to fly away.  Since we are in the age of everyone photographing and taking of video of what they see--we have documentaion of it.  Here's a photo:

The photographer, John de Guzman posted some of his shots on Flickr from September 11, 2010 and wasn't sure what the specks were--but thought they were cool.  I'll admit, it does look cool...but I know that those are birds and I know what was happening.  These are migrating birds like thrushes, vireos, grosbeaks, warblers, tanager, flycatchers, sparrows--you name it trapped and confused in the beams of light.  If they get stuck in those beams and fly in one spot all night, they lose crucial energy and time that they need in their marathon to head south.  Birds have a higher metabolism than we do and they burn their fat reserves quickly.  Would they be able to find more food (and enough of it that hadn't already been eaten) and till get down to their migratory routes in time?

According to an interview on Animal Planet's website New York City Audubon has kept an eye on the light tribute, and when they saw the gathering of helpless birds, let the Municipal Art Society know so they could shut down the beams (Migratory birds are protected by federal law).

"We have a protocol in place in partnership with the Municipal Arts Society in case something happens like it did on Saturday night," explains John Rowden, Citizen Science Manager for NYC Audubon. "There were huge numbers of birds flying through and large numbers did have difficulty navigating out of the beams. Through the course of the night we shut the lights off five times for approximately 20 minutes each time, which allowed the birds to clear out (and then new birds moving through would accumulate). The Municipal Arts Society were very supportive of our goals of minimizing risk to migratory birds." A similar situation happened in 2004 but because of the ways birds navigate the skies, and the way local weather affects their migration routes, these large numbers of migratory birds do not always pass through NYC on September 11th.

It was a relief to read that the Municipal Arts Society was willing to compromise and turn the lights off for 20 minutes at a time to help the birds move on.  Sometimes artists think in different ways than scientists and egos can get in the way, I'm happy that didn't happen here.

You can read more about it at Wired Science and below is a video of the event.  It looks like it was a pretty spectacular site.  This also goes to show that sometimes before we build, we need to take in the Big Picture.

Digiscoping Duel Photo Album #birding

I took almost 2000 photos on the day that Clay and I did the Digiscoping Duel.  I had a bunch of photos of waxwings  and other birds that showed up after the duel was over but wasn't sure what to do with the others.  I posted a photo album on Facebook and it occurs to me that not everyone is on Facebook (cough, cough, my mother) and so I put up a Flickr album of all the "good" photos (not all 2000) if you're interested in seeing more.  I like it because it shows that if you have good digiscoping equipment and use it often, you can get several good shots a day--even some bad ones, but at least identifiable ones. We do have more Digiscoping Duels planned.  We're trying to figure out dates and new challenges.  Clay and I will both be at Rio Grande Valley Bird Fest in November (anyone else going to be there?) but we'd like to do another before then.  If you have suggestions of digiscoping challenges or a suggestion for doing it someplace other than Twitter, let me know.  We'll see what we can do.

First Juncos Reach The Twin Cities #birding

Alright, winter is no longer one of those abstractions that will happen at some point--it's officially on:

Look what I found lurking in the grasses in Forest Lake, MN (it's considered a northern suburb in the Twin Cities).  Why, it's a slate-colored junco.  For non birders, this is also known as a "snowbird" or birds that nest so far north, spending winter in Minnesota doesn't seem so bad.  I posted a junco update on both Twitter and Facebook and I had reports of several juncos in northern Minnesota and a few reports on the outer suburbs of the Twin Cities--even Minnesota.  I better keep riding my bike and enjoying it while it lasts.

Speaking of Facebook, I got the coolest update today--a pair of whooping cranes showed up at Carelton College's Arboretum!  The rumor I have heard is that these are two males who spent the summer in North Dakota and are now on their northward migration but this is in now substantiated by the Crane Foundation.  I've heard that the cranes moved on, but it's cool to know that whooping cranes stopped in the Twin Cities on their southward migration.

Interesting Lecture Series At TRC

Hey Twin Cities peeps, The Raptor Center has an interesting lecture coming up on Friday, October 1, 2010, at 4 p.m at Ben Pomeroy Student Alumni Learning Center, Room 215 on the St Paul U of M Campus.  Event is free and open to the public but reservations required. Dr. David Mech and Mark Martell will talk about "Tracking Apex Predators," and specifically address their research involving wolves, ospreys, and bald and golden eagles. There will be a reception and an opportunity to meet some of The Raptor Center’s education birds afterward.

You may recognize Mark's name--he's let me tag along with him to band bald eagles, osprey, peregrines and even golden eagle tracking.  He's an awesome guy.  I've never seen Mech speak, but I love his books.

The Duke Lecture Series was established in 2006 by Dr. William H. and Mary E. Holleman, lifelong friends of Dr. Gary Duke, co-founder of The Raptor Center. The Hollemans' gift to establish a lectureship endowment fund pays tribute to Dr. Duke's work and legacy at the University of Minnesota and The Raptor Center. An annual lecture hosted by The Raptor Center features speakers on the topic of avian medicine, avian conservation, and other pertinent avian topics.
