Great Crested Flycatcher (Myiarchus crinitus)

The Great Crested Flycatcher is one of five species belonging to the Myiarchus genus, which are difficult to differentiate due to a lot of physical similarities. The Great Crested is the only migratory bird, meaning that from May to September it will be uncommon to see, and any sighting may actually be of another Myiarchus species. This species can be seen virtually anywhere in the country, in contrast to the Brown-chested and Nutting’s Flycatchers (limited to Guanacaste and northwest Puntarenas) and the Panama Flycatcher (limited to the Pacific Coast). The Dusky-capped Flycatcher is resident and can be seen anywhere in the country as well, but is noticeably smaller in size, lacks the wing bars of the Great Crested, and has a dark crown.

The pale base of the lower mandible is another field mark useful for identification, as seen in this photograph.
