As I have already related in my post about birding a shade-grown coffee plantation there was an Emerald Toucanet (Aulacorhynchus prasinus) that was kind enough to stay in one spot long enough for me to digiscope it. The green bird, which could amazingly almost disappear in the foliage, was feeding on fruit (figs? Nope, manteco, according to James). It was great fun watching it stretch and use that giant bill to delicately pluck individual fruit and gulp them down. Sometimes the bird had to use twister-like contortions to get the particular fruit that it wanted. I kept expecting it to lose its balance, considering the size of its bill, but the bill, made of keratin, is amazingly lightweight despite its size. I hope you enjoy looking at the images I got as much as I enjoyed taking them!
Of course, because nothing about the taxonomy of birds in Central America is simple, and it has been suggested that Emerald Toucanet are actually more than one species. There is a simple rundown on the Wikipedia entry for the bird (and Nick has a ton more here and here). So who wants to send me back to Central America so I can find the other varieties?
