Pesky ABA!  I mean heck, I went to Tracy Aviary 2 or 3 times last year, and 
saw another 100 or so species I thought I could added to my big year list... 
Plus all those trips to pet stores for parrots and exotic finches, and the 
roaming flock of guinea fowl in Hurricane, the peacocks in Rose Canyon, mute 
swans it seems like everywhere, and don't even get me started on Mandarin 
Ducks... Oh boy, all those hours I could have used elsewhere... ;)

Good Birding

Tim
