Naturalist notes: Ferruginous Pygmy-owl

 Ferruginous Pygmy-owl - Glaucidium brasilianum


The Ferruginous Pygmy-owl is Trinidad’s smallest owl. It measures merely six inches in length. It can often be heard calling in the early morning or late evening. They feed primarily on birds and lizards.

In this photo you can clearly see the nictitating membrane, which is a transparent third eyelid that can be drawn across the eye for added protection when taking down prey. It also helps to moisten the eye while maintaining visibility.


This is an excellent bird to mimic when birding in the forest, as it can attract a number of other species of birds teaming up to chase this predator away.
