Had beautiful looks at the adult female peregrine falcon early this evening under clear skies, low humidity, SW winds at 13 MPH, and temp around 77 degrees. It was about an hour before sunset under stunning light conditions! The adult female was perched at the rim of the nestbox and then moved out onto the wooden perch. The adult male was making aerial loops way overhead and that prompted a series of cacking replies from the female!

The 4 Lawrence Peregrine chicks are so ready to fledge! At close to 40 days old, aside from perhaps a tuft of down feathers remaining on the crown, these 4 peregrine chicks are fully developed and ready to take flight. Their next major change in appearance will be around one year of age, when they begin to molt and acquire their adult plumage as their feathers are replaced. Stay tuned!!

The Lawrence Peregrines look to be approaching 5 weeks of age and are now within a few days of being able to take flight for the first time! The remaining down feathers are now only seen on lower back, lower legs, and on the crown. The three amigos are basking in the late afternoon sun with winds from the east around 9 MPH and temps in low 60’s…..very nice!

The Lawrence Peregrines look to be a few days away from fledging, or making first flight. The age of the white pantaloons! This may happen a day or two earlier or later, but most chicks do go through this phase around Day 33 where they have large fluffs of down conspicuously surrounding their legs, much more prominently than anywhere else on their bodies. This photo shows three of the four chicks!

The Lawrence Peregrine Falcon chicks continue to grow and get bigger. The patches of remaining down feathers are becoming restricted to the base of the legs, parts of the wings, and perhaps parts of the back, as well as the crown. They are also becoming increasingly vocal and active around the nest area, to the extent that the adults rarely visit except to drop off food for them, or stand guard for a short visit.

The Lawrence Peregrine fledglings continue to grow and get bigger. The female in this photos is tearing apart prey and feeding it to the chicks. The nestbox is getting crowded and the meals are more frequent. The chicks are spending more time near the front of the nestbox! The are now using their legs fully and no longer sitting on tarsi. Banding time is very close at hand.
