New River Wish List, Post #1: Pied-billed Grebe

And now we begin looking at potential lifers (for me, anyway) I might see in Virginia at the New River Bird and Nature Festival. First, let's look at their list from this year's fest:

Holy mishmash, that's a lot of birds! Too many to format into a single-column list. Sorry! Anyway--you get the idea. We can pretty much expect to see everything but an emu down there!

So let's start with a water bird: the Pied-billed Grebe
Weird-looking duck, in my opinion. Not a whole lot of field marks, save that stubby little bill. Let's see what Cornell has to tell us: "A small diving bird with a chicken-like bill, the Pied-billed Grebe is common on lakes and ponds across North America. It is rarely seen flying and prefers to sink out of sight when danger threatens." Interesting. So we're likely to see this guy on the water. Good! Easier to spot with a scope.

Wait a second! "Although it swims like a duck, the Pied-billed Grebe does not have webbed feet. Instead of having a webbing connecting all the toes, each toe has lobes extending out on the sides that provide extra surface area for paddling." So it's not a duck! A quick check on the Animal Planet site for this bird tells me it is not a duck. The toes are weird-looking--but I can't find an illustration on-line.!

You can hear the call on the Cornell link above; it's described as "kuk-kuk-kuk, kaow, kaow, kaow, kaow, kaowk, kaowk, kawk." Check. It's on my fabulous BirdJam software on my Ericsson-Walkman phone. Sweet!

My Peterson's guide notes that the little stubby chicken-like bill is different from the longer pointy bills of the grebes; it also has no wing patches like the other grebes do. So why the differences? Why is this even called a grebe? DNA, I guess.

Peterson also notes that the breeding birds will have "a black throat patch and a ring around the thick whitish bill[s]." Good to know. Here's a photo by Jeff Foott/DCI showing both the black throat patch and the black ring about the little chicken-beak:
Seems like this bird ought to be easy to identify in the field. What looks like a smudgy brown duck could be a female mallard, for instance, unless it has the little stubby beak of the pied-billed grebe. Grebes are also smaller than the mallards, about the size of a pigeon.
That's one bird down, many more to go! If you see anything about these Wish List posts that can be improved, please let me know in the comments. I'm trying to pack as much info on here as I can, commenting on the things that stand out in my mind as ID tips.
