U.S. officials believe an increasing number birds, including the ones in these photos are deformed, but don't know what's causing the problem
As for the birds, they were observers in the background. Now they may be paying a price for all that human activity in Alaska and along the Pacific Northwest.
A study released by the U.S. Geological Survey on Monday documents that scientists have discovered an unusually high rate of bird beak abnormalities. Actually, the highest rate ever. And while researchers have no idea why, some are already pointing the finger at the activities of mankind.
"The prevalence of these strange deformities is more than ten times what is normally expected in a wild bird population," said Colleen Handel of the USGS in an article published in The Auk, a quarterly journal of ornithology.
