Calm wind becoming north 5 to 7 mph in the morning.  Tonight, mostly clear, with a low around 55. Light and variable wind.

2019.0606.1Day 33 – ‘the age of the white pantaloons’.  This may happen a day or two earlier or later, but most chicks do go through this phase where they have large fluffs of down conspicuously surrounding their legs, much more prominently than anywhere else on their bodies. 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.
