7th Ave Western Flycatcher


Hi Birders,
     Yesterday I found this late empid (see photos) in an odd place, feeding from low snags under a shady, and over a weedy water district pool along 7th Avenue between the Laguna Honda reservoir and a community garden. This bird seems to conform well to various published descriptions online of a Western Flycatcher, but none mention the almost entirely yellow-orange bill present on this individual. Any comments?
