Podrobnosti k pozorování
Observed 3 on the east side, perched in a tree overlooking the pond; one of them was calling loudly (unmistakable call, which was also confirmed by Merlin; the call becomes most recognizable beginning at about 58 seconds into 11.50 am recording). They then flew off northeast. About 12 minutes later, I observed a flock of 7 flying west over Lusitania Meadow toward the pond, also calling loudly (recording at 12.02 pm; note there is also an American Crow in the recording). They were flying relatively low, so I could observe them clearly. Neither flock appeared mixed. I believe I observed 10 altogether, but I'm submitting 5 to be conservative.
