Redtails and Squirrels - Q & A with Blakeman

A question for John Blakeman just arrived from Bill Trankle, a correspondent from Indianapolis . Below, the Q & A:
Marie, today PaleMale.com showed a shot of one of the immature hawks (the Washington Square bird I believe) where the hawk is apparently sitting on a squirrel nest (that big, untidy ball of leaves). Since John Blakeman has mentioned that squirrels are not a common source of food for red-tails, I was wondering if he'd ever observed hawks attacking squirrel nests before. Of course, without knowing the shot's context, it could be that the juvenile was just curious, or perhaps thought it a nice soft spot to land!
Time after time I have seen our giant Ohio fox squirrels run around in a tree or woodlot in full view of a sitting red-tail. The hawk seldom pays any attention. There are any numbers of photos on Palemale.com of Central Park squirrels going eye to eye with a local red-tail.
However, red-tails can and do attack and kill squirrels, either when they are hungry (having missed a meal because of bad weather on previous days), or perhaps because they want some different meal fare from time to time.
Do red-tails attack squirrel nests? I've never seen it, but my falconer friends who hunt squirrels with red-tails are very familiar with this behavior. Squirrel-hunting falconry red-tails soon learn that fleeing squirrels often duck into their large agglomerations of sticks and leaves, the squirrel "nests." The red-tail, being rather intelligent, realizes that the enclosed squirrel is protected only by lose leaves and small twigs, so the bird drops right on to the nest, or attacks it from the side, punching it, attempting to dislodge or grab a squirrel inside.
So yes, red-tails that have learned the habits of squirrels can attack a squirrel nest, often with some success. I think this might happen more often in New York parks than out in rural areas. NYC red-tails have no opportunities to take four or five field voles, the sustenance food of these birds in rural areas. Voles don't live in mowed turf areas.
Consequently, the urban red-tails have had to adapt to the prey there, which includes all the usuals, pigeons, rats, and an occasional squirrel. These tree rodents are surely seen each day by the hawks, so their every move and behavior has been much-studied by the local hawks. If Pale Male or Lola decide to have something different for lunch, a known squirrel nest could be easily punched to see what comes out.
