Cool yard bird: Black-billed Cuckoo

Lately, I have had cuckoos on my mind. There was a week or so last year when you couldn't bird just about anywhere in central Honduras without seeing at least one of the Coccyzus cuckoos – usually the more common Yellow-billed Cuckoo. But that was late September / early October, and after mid-October this year, I thought the window was closing on them, and I wasn't going to see one this year.

Then suddenly there was this hatch-year Black-billed Cuckoo in my own backyard this morning! Probably not a rarity in Honduras, where the entire North American population must pass through in migration twice a year, but all the same a species rarely reported, due to its secretive habits.

Now I need to find me a Yellow-billed Cuckoo.

27 October 2013 postscript:
Eight days later and 200 m further, Roselvy and I found an immature Black-billed Cuckoo today! According to eBird, nobody else is reporting this species in Central America this fall, and here we are with two immature Black-billed Cuckoos. Are they the same bird? It seems likely, yet I'm not 100% convinced that they are. Here are some photos of today's bird, seen along the dirt road that goes up to Cerro de Hula (Honduras). As I said, this is roughly 200 m from our backyard.

We're looking at the other side of the face, compared to last week's bird. But note the distribution of the darker color on the (lower) mandible. Here's a photo in which the bird turned its head:

Compare that to the bird at the top of this post, and tell me if it's the same bird or not.

I never did find that Yellow-billed Cuckoo...
