A little over a week ago I sent a post about a Broad-winged Hawk nest which I discovered in July 10th. Here's my original post:
"On July 10th I found a Broad-winged Hawk nest with 1 chick in it. A that time it was quite young, with an all white downy head, although the body appeared to be more like juvenile plumage. The nest was near the road but at least 100 feet up in the notch of a deciduous tree, and extremely hard to see.
I was led to the area by the mother who I heard screaming for at least 20 minutes before I went looking. By luck, when I finally got to the spot she came flying through the forest and went straight to the nest, and after some searching I spotted it. She continued calling from a tree about 200 feet from the nest, so I set up my recorder and let it run for about 20 minutes. It was a windy day with quite a bit of aircraft traffic, so the recording is noisy, but a very good example of the Broad-wing call/song, even though boring and repetitious. The recording below is a 2 minute + excerpt. Pictures include the chick taken 9 days apart. To date, mom and nestling are still doing well."
I didn't look the 2nd time until July 19, and I also included pics of the nestling with my post from that date. I checked again a week later, on the 26th, partially because I saw an adult Broad-wing sitting on a snag in a field about 300 yards from the nest and was fairly sure it would be the mother. When I looked at the nest the juvie was there, so I got my camera and took 3 pictures of him staring back at me , before, to my astonishment, he flapped his wings and then took off, going quite a distance before settling in another tree. I had no idea he (it) would fledge so quickly. I suspect that may have been the first day but not first flight. I stopped again on the 28th and he was not in the nest, but I heard him call, and a few minutes later he was 125 feet or so up in a pine tree near by. He called for help from mom intermittently but stayed put so I could get some decent pictures of him, as well as record his calls. I did hear a distant Broad-wing call but I can't say it was the mother because it never came near the nest while I was there. For reference, I found a an obvious juvenile sitting in a tree and calling on August 1, 2014, and I think that bird was a little older than this one and away from the nest, so the dates are pretty close.
I have included the same links as in the original post, but I have added pictures and the call of the juvie as well. To me, the difference in the bird from the 10th to the 28th is amazing. He had a downy white head then and even somewhat on the 19th. I didn't realize that raptors mature that quickly. Perhaps it's because Broad-wings are smaller than RT or RS Hawks. Hopefully you will be able to access the files in these folders; If not let me know and I'll try a different way. If it asks you to sign in just click the x in the upper right corner. If you view the pictures, the title and date of them appears in the upper left corner if you do NOT use the full screen option, so you can compare the juvenile at different dates.
