The tower climber, Frank Cortino, from 3Z Telecom, sent me photos of the nest with its three eggs, which I've posted. I've sent the photo of him with the bird circling to the local paper. It would be nice for the public to realize that these workers are aware of and abide by regulations to protect the birds.
Birds were first observed on Jan 11, 2015, although they obviously had been there a while. One bird was on the nest and another nearby. On Jan. 12, a cell tower maintenance climber ascended the tower and when at the height of the nest, the female rose from the nest and began circling and approaching the climber. He went a little higher and photographed 3 eggs in the nest. While the female was basically mobbing him, the male approached carrying a fish but only circled nearby. The climber descended (because they are not allowed to work on a tower when eggs or young are present) and the female returned to the nest, followed shortly by the male, who perched on a support beam just below the nest. All this was photographed, and the climber has promised to email photos of the eggs. The nest is lined with coconut husk fiber, evident in the photos.
