Lawrence Peregines: Day 34

June 7, 2019 in Near the Clock Tower

The Peregrines began the day under fair skies, calm wind, and temp at 55F. The day ahead calls for mostly sunny skies, with a high near 78. Calm wind becoming northwest around 6 mph in the afternoon. Tonight, mostly cloudy, then gradually becoming clear, with a low around 56. South wind around 5 mph becoming calm in the evening.

2019.0607.2Approaching five weeks of age, the chicks are within a few days of being able to take flight for the first time, and the remaining down feathers are usually largely restricted to the lower back, lower legs, and crown. Later in the afternoon, the chicks were just hanging out, walking around, and looking out, with some intermittent wing flapping.  It is consistently the rule for male Peregrines, in common with most other raptors, to do the bulk of the hunting while the young are in the nest, as well as during the egg stage.  The contribution to the hunting by the female varies quite a bit, but is usually small, and she spends most of her time near the nest, ready to protect her little ones against predators. At about 3 weeks old the female may do more hunting, and the male amy bring food items directly to the chicks.
