Western Wood-Pewee (Contopus sordidulus)

The Western Wood-Pewee is part of the Contopus family, a very difficult family to identify to species level in the field. It is very similar to the Tropical Pewee and the Eastern Wood-Pewee. The best field mark is the bill, were only the base of the lower mandible is orange. This species, unlike the Tropical Pewee, is a passage migrant and will only stay in the country from mid-August to November, and from mid-March to May. In similar fashion to the Eastern Wood-Pewee (and further differentiating from the Tropical), this bird will return to the same perch after a sally, so observing the behavior can help with identification.
