Eastern Wood-Pewee

The eastern wood-pewee has gray-olive upperparts and lighter underparts with olive on the breast. The wings have two wingbars and the lower bill is a lighter-yellowish. 

It is visibly indistinguishable from the western wood-pewee which has a different range in the U.S. and Mexico, but nearly the same distribution in the part of Colombia where we were at Tinamu Reserve. iNaturalist identified it as an eastern, with western as second choice, the only reason I went that direction.
