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.
