Birdchick Podcast #114: Stowaway Birds & Illegally Raising Wild Baby Birds With Cats #birding

Bird stowaway on a plane goes all the way across the Pacific. Can't wait til US Fish and Wildlife and ABC's Cat's Indoors! Campaign sees this: woman raising baby robin with her cats...I suspect she's not a licensed wildlife rehabber. (This is a terrible idea, if this bird ever gets released, it will not associate cats as predators...not all cats are so relaxed with birds, this story will not end well).

Guy taking pictures of eagles manages to get all the numbers on an eagle band and id where the bird came from--cool follow up story.

As if bird names weren't confusing enough, birders and ornithologists like to argue about whether or not to capitalize bird names.

Oh and for those trying to follow Non Birding Bill's squirrel/bubonic plague story...um...it was actually either a cat or a mouse that infected the man as he was trying to save a mouse from a stray cat...yeah, I know, it's weird.  Read the full story here.

Lawrence's Warbler

I took a quick trip down to Indianapolis to visit my family. On the way, I made a stop at Mr. Neil's and got a big surprise. I went to the spot where blue-winged warblers have nested in the past and sure enough heard the familiar 2 note, buzzy call of a blue-wing. I was excited to see one, but when I got it in my binoculars I was surprised to see something golden-winged warbler-ish...it was a hybrid!

This is a Lawrence's warbler which is some sort of mix of blue-winged warbler and golden-winged warbler. These two species are known to hybridize, the more familiar hybrid is the Brewster's warbler. This bird really threw me for a loop because it sounded so much like a blue-winged warbler. Here's a video so you can hear what it sounded like (there's also a common yellowthroat singing in the background):

I was kicking myself that I didn't wander the trail for bird watching until so late in the evening, I wished I had better light. I took both the photo and video with my iPhone through my scope...incidentally, I used the Meopix iScoping Adaptor to secure my iPhone to my spotting scope...more on that later.

I found an interesting article by by David Bonter and Irby Lovette on these two hybrids. It reads, "The most common hybrid form is known as a "Brewster's" warbler; the rarer form is known as a "Lawrence's" warbler. We currently believe that a "Lawrence's" warbler results when two "Brewster's" warblers mate, or when a "Brewster's" warbler backcrosses with one of its parent species, but research into the genetics of hybridization between these species is underway and many questions remain unanswered."

I haven't paid attention to this spot in the last few years because of my work and travel schedule. Did a golden-winged warbler mix it up with a blue-winged warbler? I can't imagine this bird coming to the exact territory where a blue-winged has nested in the past unless it hatched here. One thing is for sure, I'll be checking it more closely this year.

Here's a an article from the American Birding Association's Birding about the hybrids with lots of great photos.
