In various places in recent months I've seen discussions about identification of various Empidonax individuals that have made references to characteristics such as "primary extension", "tail length", "eye ring extended towards rear", "yellow underparts", "large headed look", etc. It seems that the art of identifying an Empidonax individual by sight may be possible under the right circumstances, or at least being able to narrow down the possibilities of which species it might be. I was wondering if anyone is aware of any resources that may exist, printed or online, that have these ID tips described in one place?
