观察细节
Several groups were heard and seen as they flew over the main portion of Hog Island. At least two “types” were heard, further ID will hopefully be made after analysis of audio recordings. The majority of the birds were making calls similar to what is in the recordings below. One individual that was separate from the larger flocks was making noticeably lower calls that were noticeably more musical (less chattery) than the other crossbills. Unfortunately, no usable recording was obtained of that bird.
