This afternoon, the male was on the oval widow of north tower at the Beresford Apartments, and the female was on the nest, which is on the oval window of the southeast tower. The ironwork of the north tower window is painted black, while the ironwork of the south tower is painted white, which makes it easy to figure out which tower is which in videos and photographs.
Not much happened while I watched. The male left the tower a few times and at one point two hawks buzzed the Beresford, most likely the Beresford male and another hawk. The other could easily could have been one of the males from the other nearby nests.
