The chicks are growing very fast. They are now about three weeks old. At this age, the diameter of their legs is full size so in the past they were banded by the Ohio Department of Natural Resources, Division of Wildlife at this age.
In 2015 they were removed, or “downlisted”, from the list of threatened species in Ohio. The Division of Wildlife will continue to monitor select peregrine falcons nests in Ohio. The Dayton nest is one nest of a sample monitoring program to assess the health of the peregrine population.
Data collected includes the presence of the falcon pair at the site, whether or not eggs are laid, how many of the eggs hatch, and how many chicks are successfully fledged at the nest. Fledging is when the chicks take their first flights around six weeks old.
The two chicks that hatched earlier than their siblings already have dark flight feathers showing through their downy fluff. By six weeks old the chicks will be as large as their parents.
The three chicks seem to be doing well. It is hard to say why the fourth egg did not hatch, but we have only had four chicks three seasons in the 16 years of the Dayton Falcon Cam.
Now the chicks are much larger and are able to move around inside the nest box.
One week ago they were unable to move very far and stayed grouped together:
