The Toucan was taken at the Summit Zoo (that's why I removed the background as it was an ugly fence).
The Hummingbirds where taken at the Rainforest Discovery Center near Gamboa in Panama, they have some feeders there and they are around allot, they are free living in the rain forest do, not any zoo. Here at my blog
Birdwatching In Panama are some details of the center and other pics as well.
Unfortunately it was overcast and I did not want to use flash as it sometimes changes the reflected colors, got do the the lens open at F4, ISO at 800 and 1/125 that time explains the unsharpness in the pics I guess. Gota try again in better light or use the flash next time. The toucan picture was taken with F5.6 ISO 800 at 1/200.
