Mourning Warbler

As I start to go through the pictures from Costa Rica, some of the best bird images are invariably closeups of birds shown to us by Dr. Bill Hilton Jr. These were invaluable teaching moments on the part of Bill and the birds themselves.

Female Indigo Bunting

Although the focus of the Operation Rubythroat trip to chayote fields in Ujarras Valley, Costa Rica, was ultimately to trap, band and release as many Ruby-Throated Hummingbirds as possible over six days in the field (more about all this in a future post), invariably, other birds sometimes got trapped in the nets. Any bird trapped was a potential teaching opportunity. Neotropical migrants were retained for banding. But after we had seen a species native to Costa Rica once at the banding table, which is where we gathered for these demonstrations, all future caught birds of that species were immediately released.

Bananaquit

With field guides in hand, we studied the birds until we were able to identify the species. Bill would only help by pointing out various field marks, but he also elaborated on other features you might never see unless you had the bird in your hand. Some species were familiar, but the opportunity to study them so closely was absolutely phenomenal. For those who are squeamish about the trapping and handling, I admit I once was too, but Bill treats the birds with the utmost respect and care. You can go to a museum and study skins, but for color and presence there is nothing like a live bird.

Blue-Grey Tanager

I have seen Blue-Grey Tanagers virtually every time I have visited the American tropics. They are ubiquitous and easy to identify. But I have never seen a Blue-Grey Tanager like this before.

The afternoons invariably turned cloudy and sometimes rainy, which made taking pictures of other birds anything from challenging to impossible. Nevertheless I managed to get some good photographs, and I will be back with many more.

These are just a sampling of some of the earliest birds we saw in the hand, and I will be back with others, as well as eventually adding pictures to my flickr page.

House Wren – the same species, but not the same population we have at home

As for the timing of this post, I woke up in the middle of the night thinking about the past week. Sleep has been erratic at best, and I’ve been emotionally exhausted. I went to bed early last night, so I guess it’s not altogether strange that I am awake at 3:00 a.m. Trying to go back to sleep I started reviewing the past week, and that wasn’t all good, so I shifted my thoughts to things I want to accomplish, which woke me up even more. When I started thinking about this post which I started to work on last night before I conked out on the futon, it seemed prudent to just wake up and finish the post. I apologize for any detectible grogginess. I think I’ll grab a drink of water and go back to sleep for a couple hours.

Yellow Warbler

Yellow Warblers and Tennessee Warblers were the most-frequently-caught neotropical migrants. At some point, we had caught so many Tennessee Warblers, we released them from the nets without banding them.
