Variable Antshrike (Thamnophilus caerulescens) - 09Aug2022

The Variable Antshrike is super interesting because as its name implies, it has such variable plumage between the male and female (sexual dimorphism) but also within all the sub-species that can be found across much of South America.  So this is one I was relying on our guide to help with ID.  My only sighting/picture was in the Atlantic Forest of Sao Paulo but we did hear them again later on the trip.  I hope to improve on pics soon, and perhaps by then they will split this species into birds with names that help to identify them based on plumage differences.
