Description: "Peefs", the first peregrine falcon produced by artificial insemination with frozen semen at Cornell University in 1986. Semen was donated by an imprinted male falcon, frozen in Lake's glycerolated medium, thawed, dialyzed to remove glycerol, and used to inseminate an imprinted female. "Peefs" was 20 years old and going strong when this video was submitted.
