Poznámky
A nocturnal recording of a flock of birds that flew overhead, but not seen. ? Brant
Podrobnosti k pozorování
I heard a "rushing" sound like "chuckling wood frogs" and it was fast approaching me from the lake, getting louder as the seconds passed. The flock of geese flew directly overhead. The sound of their wings was distinctly heard. I am not sure of the species. Help for the ID would be appreciated. I feel they may be Brant, but the birds were not seen. The estimate only from hearing their flight notes. This was a relatively large flock, judging from the time it took to pass over me.
