Black-crowned antshrike, Uraba, Colombia
This is the male, the female has similar patterns yet is dull brown instead of dull grey. This species has been split from the slaty antshrike, therefore it was called the western slaty antshrike, but black-crowned antshrike is the newer and now accepted name.
This is the only grey antshrike in its range, and can be identified based on that. Or based on the black crown, which is not visible from this angle.

The black-crowned antshrike or western slaty antshrike is a species of bird in the family Thamnophilidae.
It is found in from western Ecuador, western Colombia, western Venezuela, and Central America as far north as Belize.
It was previously included in the widespread slaty antshrike , but following the split, this scientific name is now restricted to the northern slaty antshrike.
