In the morning, I visited Randall's Island nest. I couldn't see any sign of hawks, but if they've gone back to the old nest, the female can hide fairly well. There's also a good chance that the pair moved, given the Peregrine Falcon nest nearby.
I then went to Tompkins Square Park, which is still a few days from hatching. Both hawks there looked healthy. Locals estimate the hatch date to be May 10th.
Then it was off to Washington Square to see how things were going. As usual, they continue to grow bigger and bigger. They can stand briefly and feather shafts are visable on their wings.
