The way it's going there'll be one here by the weekend.
Hi Paul, no expert but are you sure these are Least Flycatchers mate? Seem to lack the obvious eye ring... could be wrong.
your spot on rich, well done, its one of the pewee's either eastern or Tropical which are done on call and primary projection, will have to check my Mexico book when back home, (to big to bring!) or i could just photo shop an eyering in :-)
