Made an early visit to observe the Woburn Falcons and found the female hunkered down in incubation mode. She may have laid one or two eggs at this point. Also had a chance to observe further copulation activity. Typically the copulation activity ends after the third egg is laid, so we may be close to the end of the egg laying cycle!

After months of speculation among the local peregrine watchers about whether these falcon would form a pair bond; and after many weeks of observed and reported copulation activity between the unbanded male, and the not quite yet one year old banded female, it looks very much like the first eggs have been laid and the the incubation process has started.
With Peregrine Falcons, it is normal for first-time egg layers to start a bit later in the season. The eggs are laid normally about 48 hours apart, but it can be as long as 72 hours apart. Usually, full-time incubation starts after the second to last (penultimate) egg has been laid. In many nests, the female handles the incubation duties around 2/3’s of the total time with the male taking up the balance and providing the female with time off the nest.

Made a run by the Woburn falcons this morning under dark overcast skies and light rain. Both peregrines were seen with the adult having made a fresh kill for breakfast. Nice looks at the juvenile with yet another clear read on her 32/BC leg bands!

On Saturday morning, in beautiful crisp early light, the adult male and juvenile female were seen both perched and in flight. At one point, the juvenile female was joined by the adult male who flew into a regular perch location with food. This type of food transfer can be part of the courtship process…..stay tuned!
For those with an interest, 5 flight/perch photo series posted:

Quite a show watching the Woburn Peregrine Falcons this morning. The adult male was seen in constant motion around the quarry. Then it captured and ripped apart a mourning dove, at one point hauling the full body to another proximate location. the juvenile female, was seen perched on a nearby light pole and then it took in fast pursuit.
