They had four different species on display. This is the group that is nursing a snowy owl so it can be returned up North in the wild in about a month. This picture is not the survivor. That was an owl. It is against federal law to hunt or harm any raptor btw.
Snowy owl makes swift strides toward recovery:

Welcome
Started in 1976 as a volunteer project of the Wachiska Audubon Society (Lincoln, NE), Raptor Recovery Nebraska (RRN) is now a state-wide 501(c)(3) education nonprofit organization. We are volunteer-powered, rely solely on donations, and we’re the only group in Nebraska permitted by the state and federal government to rehabilitate orphaned or injured raptors.
