I think they are expanding their range in AZ, to the north, as people see them in areas south of Phoenix where they have not been before. But I don't know if they will ever get up in the mountains :( But I will give you and Cleve a personal tour of our study area and show you some birds, when we start trapping!

Absolutely! Tromping around in the desert is really fun! After this initial round, the next phase will focus on breeding biology - finding nests, etc.

Well there aren't so many fence posts in our study area! But they do congregate in both Florida and Arizona, and that was the point of this photo as was to point to their sociality, which is a bit unusual for a raptor. Not many raptor species like each other that much!

Hi Cindy -good question! I assume these caracaras may have just finished their morning meal so they have gathered together on this convenient fenceline to digest, preen their feathers, and just hang out. The are very social birds so like to be together in these groups, at least during the non-breeding season (winter) months. Now the quiz - how many caracaras can you find in this photo! Look carefully!
