They're back. The Falcons of Water Street, New York.

Incubation:
For Peregrines, incubation usually lasts 33 to 35 days from the date the last egg was laid (or the second last, if that is when incubation began). The eggs generally hatch on successive days, but occasionally two hatch on the same day, or a day or two passes between hatching. During the incubation period, the eggs are rarely left uncovered for more than a minute or two, although on very warm days the adults may stay off them for somewhat longer periods. Typically the female sits on the eggs throughout the night, and also for much of the day. The male takes over for several short shifts through the day so that the female can get away and hunt for herself. As a result, the female usually does about three quarters of the incubation herself, while the male contributes the rest. In the last couple of days before hatching the female often becomes reluctant to leave the nest, and chases the male away if he offers to take over incubation.

Nesting Mama Birds have a hot spot on their breast. The heat is relieved by contact with a nice, cool eggshell. Maternal instinct is a wonderful thing, but Mama is also turning those eggs, cool side up, for her own comfort.

Good afternoon to all! As Spring rolls out we have some exciting news for our loyal Falcon Watchers.

Our favorite mother falcon J Jaie has laid four eggs as of yesterday.

The first egg arrived on March 23, 2006, followed by one on the 25, 27 and 29th of this month.

We are all very excited and can't wait for them to make their grand entrance here at 55 Water Street.Please stay tuned to our webcam and check back here for up to date information.
