The Guam KingFisher is one of the most endangered birds in the world. This was mostly due to the unexpected introduction of brown tree snakes during World War 2. The Zoo's that have them are using best efforts to maximize the breeding of the pairs. And as they usually have two, but only the strong one will survive, the Zoo's remove one of the egg's and raise it as well.
This one was captured at the Milwaukee County Zoo. As they tend to stay in the dark area's of their enclosure, it tends to be tough to capture a good shot. This was captured with a Nikon D3, and Tamaron 300 mm 2.8 Lens.
