Lawrence Peregrines: Three eggs!!

April 10, 2018 in In the Nest Box, lawrence peregrines, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

2018.0410.1-001Up early just before 6AM, for a look at the possible third egg and the answer is YES!  This morning the female is waking up to overcast skies, wind from the NE at 5MPH, and temp about 34F.

The forecast for today: Scattered showers, mainly after noon. Mostly cloudy, with a high near 47. Calm wind becoming south around 6 mph in the afternoon. Chance of precipitation is 50%. New precipitation amounts of less than a tenth of an inch possible.


The female was moving around quite a bit late yesterday afternoon, and spent time standing over the two eggs.  It looked like she was ready to drop the third egg, but the timing was not yet right.  Looks like the third egg was laid after dark.  The time interval between egg #2 and egg #3 looks to be in the range of 56 -64 hours, or just a bit more than 2 days apart……well within normal range!

2018.0410.2Around 6:25AM the female departed for another break, and then returned and perched on the outer pole for a while, before returning to the inside of the box…




2018.0410.3Once again, she hovers over the eggs, and then nestles in back in incubation mode to keep the eggs warm.  The male has not yet engaged in incubation duties, but will do so shortly!
