I've looked through the 60 photos i took of the bird and posted  
the 10 most vital ones. Due to the larger resolution of my camera,  
these photos may be more beneficial then the ones posted earlier.  
I've got lots more if people want more views. Bob Ringler summed up  
our sighting. I would also add that the bill coloration appears  
consistent with Hammond's, ive got two photos which show a small dark  
bill with a orange/yellow lower mandible. My other question is about  
outer tail feathers. This bird clearly has white outer feathers, i'm  
wondering whether this is a significant field mark. Sibley show's  
perching hammond's and dusky as the only western empids with  
significant white there.

And click on"Western Empid".
Let me know what you think. I can zoom and brighten the photos at  
people's discretion.
