Seems to be the same leucistic raptor birders have enjoyed seeing for years. Average life of a Red-tailed Hawk (once they reach maturity) is about 6-7 years.
*Do you think there could be off-spring off this hawk? * Here's what I saw on the Internet about inherited leucism. Although *leucism* is inherited, the extent and positioning of the white colouration can vary between adults and their young, and can also skip generations if *leucistic*genes are recessive. The reduction of pigment in *leucistic* birds causes feathers to weaken and be more prone to wear.
