Today was the annual banding at Jersey City! This year only 1 chick hatched from a clutch of 4 eggs. It had serious development issues, and had to be removed and eventually euthanized. In it's place, a chick from another Peregrine nest in southern NJ was transferred to the JC nest, allowing the veteran parents to carry on with the nesting season. Strong parental instincts, a trait of the species, showed when the parents immediately accepted their "foster" chick! Today at banding, the chick was determined to be a male, and his black over green ID band reads 44/AM. The parents aggressively defended their adopted chick, divebombing the biologists on the roof at high speed!
