It used to be much more difficult to see Bald Eagles when birding in Wisconsin, but now they are everywhere. Last week I had two eagles circling over my house in the city for about 15 minutes, and they moved slowly enough that I was able to capture some photos.
DDT, hunting and loss of habitat knocked the number of Bald Eagles in the lower 48 United States to as low as 400 to 500 birds in the 1960s. But due to conservation efforts, a U.S. Fish and Wildlife Service 2020 report shows the population is now more than 316,000 birds with more than 71,400 nesting pairs.
The birds also vocalized while they were flying around our neighborhood. They make squeaky whistling sounds which is probably why movies and TV shows use the robust scream of a Red-tailed Hawk when they show eagles or the wilderness.
