The Great Grey Owl

The stately Great Grey Owl

The Great Gray Owl is an infrequent visitor to Maine. But sometimes they must “relocate” due to a lack of food in their usual habitat, the boreal forests of Canada.  Perhaps that was the case for “Ruff” who was sighted in a field in Jackson, Maine in 2008. The owner of the field in which Ruff claimed his perch was excited to have him as a tenant and let the word out that Ruff was there. He had not anticipated that his land would soon be flocked by photographers and birdsee’ers. (It was said that “birdwatchers” would not have participated in the going’s on that eventually led the property owner to call in the EMTs of the wildlife world- the wildlife rehabilitator team from Avian Haven.) But it was too late. He died two days later.

In here lies the ethics of birding. Did the constant observers impede the birds hunting and feeding habits? One visitor brought mice from a pet store to the field. Introducing kept animals into the wildlife can be harmful to them and the wildlife that feed on them.

“Owls are such great birds to see for both the avid bird watcher and casual observer. Because they are so tough to find there tends to be a mob mentality when people do report them.”

Some of the onlookers were mesmerized and appreciative of their sighing of the Great Gray Owl.

It may never be known whether or not the endless visitors, some of whom clearly stepped over the boundaries by “harassing” (chasing) the owl may have contributed to his death. According to the staff at Avian Haven, however, reported to a Boston newspaper, that the owl had “…a heavy parasitic load, anemia, signs of a respiratory disease, and evidence that the bird was in the advanced stages of starvation.” None of these conditions were acute, however. Perhaps the bird could have survived. It was a sad day when the rare and beautiful owl passed. (Wild Birds on the Fly)
