News Journal: Tracking bird populations leads to interesting finds in Delaware

So much has changed in Delaware since 1983, the last time a team of volunteers set out to assess the state’s breeding bird population. There are fewer farms, fewer forests and many, many more bald eagles nesting in the state.

“They are probably our greatest success story,” said Anthony Gonzon, the state biologist who coordinated the latest assessment of breeding bird populations, conducted from 2008 to 2012.

The picture in Delaware is not as bright for the barn owl, the American kestrel or the chimney swift, each of which depends on cavities for nesting. With fewer remote wooded areas, that type of habitat is increasingly difficult to find.
