As I was photographing Snow Geese at the Edwin B. Forsythe National Wildlife Refuge, this Harrier buzzed by me. I was concentrating on the large group of Snow Geese, so this one sneaked up on me before I noticed it. I managed to get a few quick shots before it was out of range. They work the fields gliding over the grasses, looking for food, usually rodents or even a stay small bird. They constantly fly low searching, so if you notice them a little in the distance, be patient and hopefully they work their way near you. In some areas they are also referred to as Marsh Hawks.
