After spending a few hours in Central Park I decided to amble down to the Hudson. It was intensely cold and windy, whitecaps on the river. After a bit Papa Hawk appeared and flew to a bush nearby to get a fresh branch for the nest. He worked at that branch while joggers went by oblivious to what was going on. For whatever reason he didn't get the branch broken off. He flew to the nest for about 20 seconds, then soared off. It was too cold to hang around waiting, but what a nice treat, one low-down Daddy-to-Be (fingers crossed).
