Surrounded by dozens of red-winged blackbird nests in a roadside marsh near where I live, I decided in May to try to discover what "unseen wonders" might be occurring in my own backyard. So I strapped an old camera to the end of a 12-foot telescoping boom pole, stuck the other end into the marsh mud, angled the lens toward the nearest nest a long reach away, pressed "record," and walked away. I couldn't see very well through the view screen in bright sunlight, so my aim and zoom settings weren't perfect (making it appear in some shots that the camera was closer to the subject matter than it actually was), but on the whole, decent footage was waiting when I retrieved the camera — most notably, an egg in the process of hatching, and the incredible process the red-wing mother followed to extricate the new chick from its egg and prepare it for the world.
While I think anyone desiring a "bird's eye view" of a red-winged blackbird hatching will enjoy this video (web link posted below), my primary motive for posting here is to ask a question. From timecode 02:05 to 02:22 the mother attends to the chick with a precision that brain surgeons would envy — but what, precisely, is she doing?
If there are any hatching-egg experts tuning in here, I'd love to learn more about the mother's behavior, and the chick's need for her specific attention depicted, at this point in the video. In advance ... thanks!
