Dusky-capped
Flycatcher, Myiarchus tuberculifer
No rufous in the tail is a good indicator that this is a Dusky-capped, rather than an Ash-throated or Brown-crested, the other two
Myiarchus flycatchers regularly found in Arizona. This bird's vocalizations are also distinctive: a high plaintive whistle, and a song
with a trill in it, contrasting with the scratchy calls and songs of the other two Myiarchus in the area.
Above, an unusually pale Dusky-capped, with almost no yellow on the underparts, maybe even an abnormal absence of pigment. The straight slender bill and the absence of rufous in the tail identify the species. Below, a more typical Dusky-capped, with relatively bright yellow underparts. This bird was photographed in Ecuador; the species ranges as far south as northern Argentina.
