If We Can Rock Together, We Can Flock Together
10,000 Birds
FEBRUARY 28, 2012
Here is a flock of endangered species. Des Lacs National Wildlife Refuge, North Dakota. These Black-legged and Red-legged Kittiwakes only need to fear gulls and Peregrine Falcons , although bad weather and erosion do take their toll on nests. I think you need to have at least three birds to constitute a flock.
