City birds outnumber suburban and country cousins in this count

Birds descend from the sky at dawn to take a break after their red-eye flight migrating south.

Where do they get breakfast and other meals to refuel for their journeys south, with some flying thousands of miles to reach their wintering grounds in South America?

During fall migration, Hays Woods, Pittsburgh’s newest park, hosts more birds than comparable suburban and rural sites, Bird Lab’s five-year banding survey shows.

At Hays Woods last week, wood thrushes and warblers paused for food and rest in greater numbers and diversity than expected.

The match-up between the three different environments during bird migration was deliberate.

The bird banding project helps researchers learn how migratory birds use local habitats at sites with different degrees of urbanization and human impact.
