MILWAUKEE (WKOW) -- Wisconsin's population of bald eagles is growing. Nesting pairs have been spotted in almost every county.
A Milwaukee Journal Sentinel report says this year's population is expected to beat last year's record of 1,337 nesting pairs.
Since eagles are primarily fish eaters, many of the nests are along the Mississippi River and near Lake Superior. The densest populations are in forested areas of Oneida and Vilas counties.
Experts say the eagle population is recovering because newer generations are more tolerant of humans.
The Department of Natural Resources conducts a population survey every year. During April, pilots fly low over trees to look for adults and eggs in nests. This month, they'll be surveying nests for chicks.
