About These Birds
Eurasian Eagle-Owl
The Eurasian eagle-owl is one of the largest owl species in the world, with females sometimes reaching a wingspan of nearly two meters. Its deep booming call can be heard up to four kilometers away on calm nights. These apex predators sit at the top of the avian food chain, preying on other raptors including buzzards and smaller owls.
Keel-billed Toucan
The keel-billed toucan is the national bird of Belize and one of the most recognizable birds in the Neotropics. Its oversized bill, which can be a third of its body length, is actually very light due to its hollow honeycomb structure. Toucans roost communally, with up to six adults squeezing into a single tree cavity.
