The Whitewing Dove (Zenaida asiatica) is another of those species that seems to be moving North. 30 years ago they were unheard of at this latitude and altitude. Now they're commonplace, even resident, in the Verde Valley of Central Arizona. This is the normal "sittin' around in a tree telling the neighbors I'm alive" call. Excuse the noise - it's from "downsampling".
White-winged Doves (Zenaida asiatica) are both permanent residents and neotropical migrants in Costa Rica, mostly along the Pacific lowlands. They are also one of the birds that frequents my yard in central Arizona, so it is a treat to see and hear them down south, too. This is their typical song, recorded near Orotina, 11/98.
