Stories tagged peregrine falcons

The first two of Belinda's five eggs hatched early this morning. (Belinda is the resident peregrine falcon in the nest box at the King power plant in Bayport, MN.)

Chicks 1 and 2: Baby peregrines are helpless at first, and are cared for by both parents. But they grow at an astonishing rate, and should be ready to leave the nest for the first time by the end of June or the beginning of July.

The other eggs, if they hatch at all, should follow in the next few days.

Hatch today?

by Liza on May. 19th, 2011

Well, it's May 19, the estimated hatch date for the peregrine falcon chicks in the nest box at the King power plant in Bayport. Haven't seen any chicks yet, but Belinda's made a little moat of pebbles around the eggs -- the folks on the Raptor Resource forum say that's something she always does right before hatching. Stay tuned...

The fourth, and last, of the peregrine falcon eggs in the nest box at the Sherco power plant hatched sometime on Saturday. The hatchlings may be helpless, clumsy, and funny looking now, but in a few months they'll be sleek, fearsome avian predators. Keep watching the falcon cam, or the daily stills, until they fledge in a few months.

The first of the eggs out at the Sherco nest box has hatched, and it looks like two others are well on their way.

Big surprise! Sometime between Tuesday and yesterday, the fourth egg hatched. (This youngest bird hatched out of the first egg laid, and we didn't have high hopes for it.)

The whole brood: This shot, captured yesterday, shows Athena and all her chicks.

The young birds will grow fast, and will fledge--leave their nest--sometime in mid July. They'll stay with their parents for about two months afterward, learning to hunt. First the parents catch prey and the young birds learn to snatch it from them in mid-air. When they get good at that, the chicks start learning to hunt on their own.

Here's the sobering truth, though: On average, only two juveniles successfully fledge per nest. And the first year is dangerous. But a peregrine that survives the first year has a good shot at a long life. Some birds have even lived to be 18-20, but that's not typical. An average lifespan is more likely somewhere between 2 and 8 years.

Visitors to the museum get to name falcon chicks. Right now, we're taking name suggestions. Later on, we'll turn those into a visitor poll, and the names with the most votes will go to the chicks.

“Athena”—the female peregrine falcon at the High Bridge power plant nest box—laid her first egg of 2007 on Sunday, April 15. Peregrines usually lay three or four eggs each year, so we'll be watching for more in the next few days.


Athena's first egg, 2007: Hard to see, but it's there. (It's the orange blob by her foot.) Congratulations, Athena.

The male and female falcons share the 33-day incubation duties, which include turning the eggs regularly. (The birds don't incubate the eggs in earnest, though, until they've laid all the eggs they're going to lay.) If all goes well, the baby peregrines will hatch sometime in the second half of May.

The peregrine falcon "Athena" was spotted at the High Bridge power plant next box on January 25th.

Athena nested at the High Bridge plant last year with the former resident male, "Smoke." An unidentified rival male killed Smoke early last May, and last year's nest didn't produce any young.

We have not seen a male with Athena yet this year.
