The Rufous-browed Peppershrike is a member of the vireo family and can be found from Central Mexico south through Central America and into most of South America. It is generally found in the upper canopy of trees and tends to be very vocal all year round. Its song, which it will repeat over and over, kind of sounds like someone saying “Do you wash every week?”.
Here is a link to the sounds made by the Rufous-browed Peppershrike.
It is an omnivorous bird feasting on pretty much anything small enough that is moving or looks edible. We were walking along a side road in northern Yucatan when Claudio Lopez (bird guide extraordinaire) heard it call. In this particular series of images it was eating the berry of a shrub along the path we were walking.
