About the middle of February, I commented that the behavior of two Red-tailed Hawks indicated that they would likely nest in Eliza Howell Park again this year. I can now report that I have found the nest. It’s great to have this raptor nesting in the park again!

The basic strategy for successful bird nest hunting is to let the bird lead one to the nest. Using three pieces of information:
- where I have most frequently seen the hawks soaring during the last month;
- the fact that they call/scream most when I walk in a particular section of the park;
- the location of last year’s nest (they are one species that may re-use a nest from the previous year);
I knew the general area in which to look. The plan was for a one-time-only approach, simply to confirm the fact of nesting. After that I would observe only from a long distance to minimize disturbance.
Because there are no leaves on the trees yet, the nest was not hard to find.
The nest is bulky, made of twigs with a finer lining inside, and may be over a foot deep. Hawks can be in a high nest like this without being visible from below. Right after I took this picture, a hawk flew out and scolded me. I headed away immediately, satisfied. It is likely that there are 2-3 eggs in the nest, which need to be incubated for about a month.
This begins one of my favorite annual bird-watching activities, locating active bird nests. I observe an “active” bird nest when I see it being built or see a bird on it or entering it/exiting it. I don’t consider a nest without the bird an active nest. In the winter, when leaves are down, I often see additional no-longer active nests that I have missed during the previous breeding season.
In each of the last three years, I have located the active nests of at least 16 different species in Eliza Howell Park. Over the years, I have found the nests of 37 different species here.
Most are song bird species and each year in early June, Detroit Audubon sponsors a breeding bird walk in Eliza Howell Park during which I can guide participants in their observation of nests and nesting bird behavior. Baltimore Orioles are among the EHP nesters each year.
