Speaking of Cassin's and the recent "trifectas" thread, here is a good CO challenge: how many bird species named after John Cassin can you find in one day? Here are the possibilities. 4 Cassin's species in one day in CO maybe, but getting all 5 will be hard! In my dreams...
David Suddjian Ken Caryl Valley Littleton, CO North American species named for Cassin include: - Cassin's Auklet (*Ptychoramphus aleuticus*) - Cassin's Finch (*Carpodacus cassinii*) - Cassin's Kingbird (*Tyrannus vociferans*) - Cassin's Sparrow (*Peucaea cassinii*) - Cassin's Vireo (*Vireo cassinii*) -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
