2017 Fledgling Peregrine Falcon

August 7, 2017 in On the Clock Tower

_W7I3938-001As the weeks move by, three of the four young peregrines that fledged this year continue to be seen around the Clock Tower and other nearby perch locations.  They remain somewhat dependent on parents for food and protection.  This was a late afternoon visit with one of the fledglings perched on the west side of the tower on an upper ledge just above the clock face.  No luck on being able to catch the leg bands for a positive ID!

Peregrine Falcon fledgling: Verizon Tower!

August 7, 2017 in Verizon Cell Tower

_W7I3895-001While scanning for Peregrine Falcons from near the Clock Tower mid-morning, saw a perched bird on the Verizon Cell Tower on Hampshire Street and made way over for a better look.  It was cloudy and overcast, but was able to get nice looks at one of the fledglings. It had a color-coded leg band but was unable to make out the alphanumeric code.  The fledglings usually find their way over to the Cell Tower after fledging for visits from time to time!

Peregrine Falcons: Watertown

_W7I0116-001Made a visit to look at the Peregrine Falcons in Watertown.  It was just as a heat wave was subsiding and the late temp was moving down into the high 70’s.  One of the adults was seen on a ledge, on the SW corner of the building.  It was still panting from the heat and keeping it’s wings a bit spread and lifted up to keep cool.  Another adult was nearby and one chick, had fledged and was on a lower ledge beneath the nest box.

Peregrine Falcons: Boston University

_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!

Lawrence Peregrines: fledgling in the shade

July 26, 2016 in On the Clock Tower

_W7I7045-001In the hot and humid weather, the fledglings have taken to the shadier perch locations around the Clock Tower.  In the morning, under the blazing sun, they tend to favor ovations on the west side of the building.  On many days, it provides a cooler perch and on many days this side provides exposure to SW winds.

Lawrence Peregrine: fledgling perched on Verizon Cell Tower

Stopped by the Clock Tower late afternoon and scanned for peregrine falcons.  After scanning for over 15 minutes, finally made a sighting of a distant peregrine perched on the Verizon Cell Tower located about 1/2 mile away in NW direction.  After getting closer, was able to get good enough looks to determine it was on the of the 2016 hatch year fledglings!_W7I5144-001

July 18, 2016 in On the Clock Tower

_W7I5080-001One of the 2016 hatch year fledglings continues to be seen in and around the Clock Tower.  This morning, under bright sunny skies, a fledgling was seen in one of the normal adult perch locations, on a ledge, just above the west face of the Clock Tower. It remained in place for over 20 minutes in an upright posture with both feet down and wings held tight against the body.

Lawrence Peregrines: mock combat!

July 13, 2016 in Near the Clock Tower

Stopped by the Clock Tower in Lawrence last night just after 5:30 pm. Terrific late day light with clear skies,
winds blowing around 15 MPH with gusts over 20 MPH, and temperature about 90 degrees.

Observed one of the peregrine fledglings in aerial flight with large loops and infrequent diving stoops. Quite
an exciting show from the young fledgling. To my surprise, another fledgling joined the fun and the real show
got underway!

For over 20 minutes, they proceeded to engage in an amazing demonstration of playful mock combat. Here is
an explanation of mock combat from Cornell’s Birds of North America:

Play occurs mainly in young. Immatures will pursue adults, siblings, prey, and attack inanimate objects.
Playful pursuit of siblings begins 2–3 d after first flight, mock combat between siblings begins 4–5 d after.

Mock combat progresses from flying parallel and occasionally rolling to extend feet toward siblings, to making
short darting dives and grappling in the air, to using air currents to make vertical stoops. Latter develops within 3 wk of flying. Play in falcons may be an expression of joie de vivre or it may simply represent the maturation of neuro-muscular coordination and central control mechanisms involved in agonistic behavior and pursuit and
capture of prey.

Lawrence Peregrines: fledgling perched atop Clock Tower!

July 12, 2016 in On the Clock Tower

_W7I3857-001The Lawrence Peregrine fledglings have been a challenge to find these past few weeks.  They have scattered from the nearby rooftops and overall sightings have been few and far between.  It was a nice treat to located one of the fledglings late this afternoon as it perched on the weathervane atop the Ayer Mill Clock Tower!

Lawrence Peregrines: fledgling building flight muscles!

June 21, 2016 in Near the Clock Tower

After fledging, the young peregrine falcons continue to work at strengthening their flight muscles. They are frequently seen near the natal site flapping their wings and preparing for increasingly longer flights around the local area. This young male fledgling was recently seen with two other siblings on the corner of a rooftop of an abandoned warehouse building in the late day sun! Notice the leg bands, black over green, 85/BS.

For those with an interest, 5 photos of the flapping male fledgling:
