Probably a budgie! A few years ago I was wandering around Rosetta MG with my heavy gear, looking for butterflies, and Big Frank came over and pointed to the top of one of the evergreen trees. 'Hunter', the resident redtail hawk, was on squirrel watch and may well have been the first bird I shot with my 100-400 lens.
Btw, Leslie, have you seen the waxwings that hang around the pond adjacent to the golf course in Earl Bales? Since I've photographed waxwings feeding their young in the lower park, I assume they are nesting somewhere in the park.
