I was there today @ Merrill looking for the gyrfalcon along with dozens of other birders.
Nothing much to report. The coolest part was when the 20,000 snow geese on the lake would take off because a bald eagle flew past them. Quite a ruckus .
According to NJ birds and a guy at the tower lookout they saw the gyr today, Sunday, perched along the cove to the left of that lookout spot.
There was some excitement when someone shouted "Falcon"!! from behind and we all turned around to see a large falcon flying past to the West. This bird looked dark and flew in a level flight. To me it seemed to have a deep wingbeat and it had a weird looking feather on the leading edge of its left wing elbow.
The guy with the biggest scope there ID'ed the bird as an adult peregrine. I've seen a lot of peregrines and I thought the wingbeat was deep and this bird wasn't really hauling along. That is just my opinion.
Anyhow I live 10 miles from the reservoir so I am going back tomorrow . A gyr would be a life bird for me!
