Peregrine Falcon Web Camera
The falcon family has left the nest. We hope you enjoyed watching them. We hope they again nest in the box in February 2014 so we can provide another video feed.

Any sign of the the peregrine falcon family?
At last check, all the fledgling chicks are doing fine. The parents are still feeding them, and I'm sure the workers at the energy center can hear the youngsters scream when the parents bring food into the vicinity of the box.
When the chicks see a parent, even if it doesn't have prey, they will fly up to greet the parent in anticipation of grabbing food. The chicks are always hungry, so the first chick to make it to the parent will get the food. I'd bet the chick with the food gets chased by the other chicks, and if the first chick isn't fast enough, the others will steal the food.
A couple of you said you recently saw an adult at the box. If a parent comes in with food and none of the chicks are within sight, the parent may fly to the box out of habit.
How many clutches do peregrine falcons have a year? Are they mates for life?
Raising even one young peregrine is a big-time expense for the parents. With SiouxZee and Coal, courtship starts mid- to late-February; the first egg is laid in mid-March; the first chick hatches mid- to late-April; the kids fledge in early June and they don't become independent of the parents until early to mid-July. That's five months. If the parents started the whole process, say in mid-July, the second set of kids wouldn't be fledging until about mid-October. That wouldn't be enough time to beat cold weather. Also, the timing of fledging coincides with young prey birds fledging, so the peregrine youngsters have a large prey base. In mid-October, the odds of them catching easy prey would be way less, so the probability of the chicks surviving would be way less, too.
Peregrines do mate for life, but if one of the pair dies, it is replaced quickly. This scenario probably happened this spring with a peregrine pair in Kansas City. For reasons of territorial defense, it is to the surviving mate's advantage to secure another mate as quick as possible.
Will SiouxZee and Coal come back next year?
We do hope SiouxZee and Coal return next year, but nature is quite harsh, and there's no guarantee one or even both will be back. If one or both aren't, I believe there's a good chance the territory will be occupied again. With all the prey birds that travel up and down the Mississippi and with such a great box to nest in, the territory is prime real estate for peregrines. We will have to wait and see.
Thanks for the questions!
