Our female falcon is back, and she does not seem to be in a good mood. She has been sitting on the perch, stretching her neck and yelling (for lack of a better word) at whoever is flying around. She looks all puffed up, and I don't know if this is because she is angry, or if this is how she always looks. Anyway, whatever is out there, she is letting them know that she is not to be trifled with.
