Now considering a pewee species
Ok, so now we are considering wood-pewee. Below is a Western Wood-Pewee I photographed this morning, actually within 50 feet of where I photographed the bird above yesterday. Birds of North America online describes W Wood-Pewee bills: "Upper mandible is black; lower mandible is mostly black, or black-tipped, pale toward base. Gape yellow". That is my experience and what the photo below of a Western Wood-Pewee shows.
