As of this morning, the egg count is up to THREE! Even though in a previous post I explained that incubation doesn't generally begin until most or all of the eggs have been laid, yesterday's cool weather in Columbus (high only about 35F) had the adults pretty tight on the eggs most of the day. Temps will warm a bit today and some sun is in the forecast but even so, from this point on (3 eggs) we'll mostly see an adult setting on the eggs. Durand will take care of most of the incubation duty. Spark's main job is to provide food for her and to take over incubation while she leaves the nest to eat. He may spend his time when not hunting on the nest ledge or elsewhere nearby but probably won't be in view of the cameras much except for when they switch places.
We'll post more info about what to expect during incubation and how to tell the adults from one another in the near future. In the meantime, check out the Falcon Facts
on the Ohio Division of Wildlife's website.
