Lawrence Peregrines: ready to fledge

June 12, 2017 in In the Nest Box

_W7I9852-001During a late afternoon visit to observe the nest box action, had a wonderful opportunity to see the chicks moving around the outer ledge of the nest box.  As happens at this stage of growth, there was lots of wing flapping and movement by the chicks.

Of particular note was watching the female go out on the perch a number of times and show the chicks how to do so.  she demonstrated how to balance and not fall off.  Then she took off into flight in to the west.  As she lifted off, her talons remained out, not tucked under in normal streamline fashion.

_W7I9895-001She was making a very short flight to a nearby rooftop to show the nestlings how to prepare for first flight!  she remained on the roof for a few minutes and then took off in a flash.

_W7I9206-001At least 2 chicks were seen playing around and wing flapping atop one of the high rise towers at Boston University.  The 2 chicks were seen near the nest box with both adults perched nearby and keeping a close eye on the chicks!

The feeding frenzy continues!

2017.0528-001Around day 16, dark spots can be seen along the edges of the wings, indicating the growth of flight feathers underneath the covering of down.  The down on the head also begins to take on a rougher texture around the stage of growth!

Day 16 and growing!

2017.0527-001Just before 6AM, the Falcon Cam showed the chicks huddled in the corner with the female perched outside the nest box, keeping a close on her brood.  Around Day 15 the chicks are beginning to enter the hunchback phase, during which they are often seen in a hunchback pose, with their feet splayed out in front and head angled forward.

4 Chicks: where did they go?

2017.0526-001A year ago, a frantic email came in, with a desperate question from a teacher with a group of students, on what happened to the peregrine falcon chicks?  From time to time, they huddle just under the camera and just out of sight.

At first look, a regular viewer might think they  jumped from the box, or something else.

No worries, just momentarily out of sight!

Moments later the female showed up with yet another fresh catch for breakfast!

Falcon Cam provides terrific views!

2017.0525-001As the peregrine falcon chicks approach two weeks of age, the chicks are beginning to sit upright more often, but still lean on each other, or against the nest box much of the time.  The very beginnings of wing feather development are also seen around this time!

Another morning feeding!

2017.05.24-001The chicks are now approaching two weeks of age and growing bigger each day with nonstop appetites and feedings!

4 chicks eating and growing quickly!

2017.0523-001A mid morning visit to nest box by female with prey in hand….she is ripping apart freshly caught prey and feeding to ever hungry chicks!

By day 11, the beak is already beginning to acquire a slightly yellow tinge, as opposed to the pink color it has had to this point in the chick’s development.
