Panamanian acorn woodpecker Melanerpes formicivorous striatipectus. Good find, I spent a long time in Mundo Maya but was mostly looking for the black and white hawk eagle, which I never found. I did find quite a few hummingbirds, however.
@jayjds2 I looked and looked on my own, only finding the tyrant and ornate hawk eagles on my own. I asked the keeper who said the black and white is off exhibit, but gladly pointed out where to find the crested eagle and what region of the exhibit it hangs out in. The ornate hawk eagle is now the only one I cannot reliably find (it has many places to hide), since the black and white is no longer an option.
@d1am0ndback perhaps ironically, the only one I never had trouble finding was the ornate hawk eagle (and of course harpy, but those are in their own area). I only saw crested twice, and tyrant three times. I would always look straight up from the first lookout area in Mundo Maya (right after the jaguar if memory serves).
@LaughingDove If you have poor vision this place isn't for you. Most of the birds tend to stay at the very top of the aviaries (which is very high). I usually find one or two new birds every time I go.
@Hyak_II I had to look it up in the aquarium's history book. The species I saw most often was violet-crowned hummingbird Amazilia violiceps. I also saw on occasion Puerto Rican emerald Chlorostilbon maugeaus and sparkling violet-ear Colibri coruscans.
@LaughingDove that is true. I think there are more species of birds than fish, mammal, invertebrate, amphibian, and reptile combined at this facility. Unfortunately, that doesn't mean you'll see any of it. Even the big birds like the eagles were a challenge...
