The male was on the nest and stayed longer than the female would, as I approached. He made a lot of scolding notes as he took off and as long as I was near the nest or within 50 feet of it. All this time the female was observed to be perched on a fence post 200' away, while the male was taking over incubation duties. Robin: Our robin's nest with 4 eggs had the female sitting on the nest, continuously while carpenters worked on a house within 10 feet of her. Nest is 6 1/2 feet high in a lilac bush.
