Bridge Magazine recently reported that bird flu is killing Bald eagles in Michigan:

at least 18 eagles in Michigan that have lost their lives to bird flu so far this year, according to testing data provided by the Michigan Department of Natural Resources’ Wildlife Disease Laboratory. Results from 16 more suspected cases are pending. If they come back positive, that could bring the total to 34.

In the middle of the last century, the nation’s eagle population was devastated by the introduction of the insecticide dichloro-diphenyl-trichloroethane or DDT. It wreaked havoc on eagles which, as predators, ingested the chemical compound in high concentrations. But then, starting in 1972, a series of steps were taken to restore the eagle population. DDT was banned, bald eagles became federally protected, and some eagles were bred in captivity before being released into the wild. In Michigan, annual aerial surveys showed breeding pairs rose from 52 in 1961 to about 835 in 2017.

“They’re a population that, if there’s going to be some sort of impact, they’re going to be really slow to rebound,” said Julie Melotti, the pathologist for the Wildlife Disease Lab. Unlike rabbits or mice that reproduce rapidly, bald eagles take five years to mature and then lay two to three eggs a year.

Kevin took this last month at Grand Ravines park. He’s been sharing awesome pics of eagles with us for years & says they like to sit in this tree and wait for the sunrise. See a bunch more in his Birds of Prey gallery on Flickr!
