This season's record-setting irruption of snowy owls, a raptor species that usually sticks to the Arctic north, has bird photographers in the U.S. all atwitter about the opportunity to capture such a gorgeous species on camera. One of these photographers is Larry Keller, who lives in south central Pennsylvania where the snowy owls began to arrive in late November of 2013.

"I saw my first snowy owl about 40 years ago and this is the first time I’ve seen any since," says Keller. "There have been a few in Pennsylvania in past years, but nothing like this year. We have at least six snowy owls in Lancaster County this year and all six are still here in early March."

Because of their rarity in such high numbers on the region, the birding and photography communities are snapping the chance to view these birds in the wild.

"The Lancaster County owls are all in the Amish country farmland. Birders and photographers have come from all over the East Coast to see and photograph these birds," Keller says. "Every day of the week you’ll find a dozen or so cars along the road and a group of birders and photographers watching the owls, which are mostly sitting in a field sleeping. I go out before sunrise and photograph and watch the owls till I see they are going to roost for the day, usually an hour or so after sunrise."

Keller, a retiree who photographs birds and wildlife on a daily basis, has been one of the more avid watchers, and he has captured beautiful portraits and interesting behaviors with his camera.

"My most memorable moment photographing these owls has to be the morning I had two owls fighting or playing right in front of my camera. I was focused on one light-colored (a male) snowy when out of no where a darker owl (a female) flew into my frame and jumped on the owl I was photographing. I had no idea that owl was even in the area," he says.

It isn't just people in the general vicinity who have enjoyed the irruption. Fans of Keller's photography have been experiencing it through his images, and loving everything he posts on Flickr. He also has some wise words for those who want to view the owls in person: "Please don’t stress these birds by trying to get closer. Snowy owls don’t seem to be afraid of people, but I don’t think they want to be friends either, and trying to get that close photo will only flush them and stress them. Watch from a distance, stay still, and be quiet. I would like everyone viewing or photographing these owls or any wildlife to remember these are wild birds and animals. Though many of my images look like I was very close is a little misleading. Most of my images were taken from 80 to 100 yards or more."

"A snowy in flight is so beautiful that no words can describe it — every time I see one in flight my heart races. To think that these birds traveled the distance from the Arctic to spend the winter here is just incredible, and now they have the flight back home."
