媒体文件注释
Sound a lot like mallards but compared their calls to the recordings of females flight calls in Sibley and it is a match. I also observed them taking off while calling.
观察细节
Saw about half of them before the whole flock took off. Counted after they were spooked and flushed. Difficult to count as the large flock circled in the sky. Counted by 5s several times. This seemed a close estimate (+/- 5 I think).
