Hearty welcome to Alaska's mosquito-gobbling swallows
|
|
Alaska, United States |
The swallow that makes the biggest dent in insect populations in these parts is the cliff swallow. These birds can nest in colonies of several thousand given the right conditions. The largest group of swallows Im personally aware of is on the middle Porcupine River, where the cliffs of impressive Howling Dog Canyon host at least 4,000 swallows.
