[cobirds] Re Mike Britten's bird song quiz

Hi all

After going 0 for 4 on these  bird song quizzes and risking being sent off to the minors for some extensive audio re-tooling, I'll take another swing.

Since the Cassin's Finch has a numerous call types, I think in the past I've recorded a call similar to Mike's quiz bird !!
