![]() Photos are always helpful for confirming the species and band codes. Please contact these biologists for peregrine sightings in each state. In your email, please include date of observation, detailed description of location, and any behavioral observations. Juveniles are more heavily patterned below than adults, and can be quite brownish above. Dark mark below each eye varies in shape and size. Always look for a grayish back in adults, long wings that almost reach the tail tip, and powerful but slender build. Please contact The Center for Conservation Biology with information regarding sightings of Peregrine Falcons in Virginia. Peregrine Falcon - eBird Sleek, fast-flying large falcon. In addition, falcons that are hacked in cooperation with the National Park Service can have colored tape temporarily covering one of the bands. In Virginia, all falcon nestlings are banded with an anodized green US Fish and Wildlife Service band on the right leg and a bi-color alphanumeric band on the left leg. When reading a band, an observer should note the top character and its orientation (vertical or horizontal), the top background color, then note the bottom character code, orientation, and color.įor example, below are a mated pair of falcons from the Berkley Bridge in Virginia.īerkeley Bridge Male: Black 6 over Red horizontal D (Type 17) There are also several orientations and alphanumeric character arrangements on the bands. Falcons in the Eastern US are banded with either BLACK over RED (1989-2004) or BLACK over GREEN (2000 – present). To report seeing one of these bands, visit the website.Ī second bi-color band is fitted on the falcon’s opposite leg and includes a field-readable alpha-numeric code. The band is inscribed with a unique 9 digit code that allows birds to be identified during future resights or captures. The standard leg band for Peregrines is a silver metal band issued by the federal Bird Banding Lab. Peregrine Falcons are fitted with metal leg bands to provide researchers with valuable data on peregrine survival rates, dispersal distances, and population growth rates.
