I associate the arrival of a northern waterthrush with the start of the southward songbird migration.

Are hummingbirds really pugnacious? Many observers think so but I say they are not always feisty.

An estimated 2,800 birds were migrating over the Vineyard on the night of August 14, with a peak of 800 birds flying at dawn on August 15.

Mourning doves are seldom mentioned in this column because they are common.

In late July adult shorebirds that nested successfully arrive, having left their fledglings alone on the Arctic tundra.

I do not normally get up at 5:30 on a Saturday morning.
