Northern Harrier

(Circus cyaneus)


©Greg Gothard 1997

Northern Harriers usually fly low to the ground using their hearing to find food. The white rump patch is a good clue that you are seeing a Northern Harrier.

Length: 18 inches

Wingspan: 43 inches

Weight: 15 ounces

This Northern Harrier was photographed at Hawk Hill. Be sure to go to the "Hawk Talk" and banding demonstration. They are given mid September through mid October, weather permitting, on Saturdays and Sundays at noon and 1:00PM respectively.

If you find a bird other than a pigeon with an aluminum band, please call and report the find to The Bird Banding Laboratory. The call is toll-free and the number is 1-800-327-BAND (2263) from anywhere in Canada, the United States and most parts of the Caribbean. Please have all the information on the bird band with you when you call. They will need to know the band number, location you found the bird, the date you found the bird, and how you got the band as well as your name and address. The sole purpose of 1-800-327-BAND is to make it convenient for people to report recoveries of birds banded with service bands. Please do not use this number to call about other matters. The 1-800 number is NOT for reporting pigeon bands. The Bird Banding Laboratory does not keep any records on the bands used on pigeons.
