[birding] First-of-year bogus Cassin's Vireo!

[Joel Geier]

Hi again,

I forgot to mention, as of yesterday (15 Apr) a PURPLE FINCH that's been
singing around our yard for a week or two suddenly switched to doing a
Cassin's Vireo imitation (a bit too fast & too rich to be the real
thing). 

I think others have commented, it seems like they do this every year,
not long before the real Cassin's Vireos show up.

Happy birding,
Joe
