Evidence now suggests that the nesting Cooper's Hawks at our home in Bristol Tennessee have young about 7-10 days of age. If the determination is correct, eggs were laid during the first week of May or by Mother's Day Weekend. The nest probably has about four young because the species lays three to six eggs. Eggs would have been laid every other day. She most likely began incubation with the third egg and not the first. Incubation usually take as much as 30-32 days. Today, for the first time, the vegetation beneath the nest is becoming noticeably speckled with whitewash, indicating the young are old enough to stand with their backs at the edge of the nest and defecate over the side. This is the evidence on which the timeline is projected for this nest. Only one or two tiny and suggestive splashes had been seen previously. If these projections are nearly correct, the nestlings are about 25 to 30 percent thru their daily development stage until they fledge at about 4 1/2 weeks. Let's go birding.....
