Lawrence Peregrines: male and female on Verizon Cell Tower

August 11, 2016 in Verizon Cell Tower

_W7I0510-001The Verizon Cell Tower has been a very regular perch locations for the Lawrence Peregrines these past two months.  Both the adults and two of the hatch year chicks have been seen with some frequency.  This sighting was  just the two adults.  It was nice to zero in on the alpha numeric bi-color  leg band (6/4) in the photograph and to confirm yet another sighting of this long-time male peregrine.

According to Christian Martin at NH Audubon, the male (6/4) in Lawrence was born in Manchester, NH in 2001 to a first year nesting pair. There were four chicks in the brood and he was the runt of the brood. The big question at that time, was, will this runt of the brood make it to adult life?

As of February 2012, the runt of the 2001 brood is the only one to survive from the original group. This Peregrine Falcon has a very healthy breeding history with a history starting in 2003 at this site in Lawrence.

His leg bands are 6*/4* black over green. The “*” indicates that the numbers are not vertical, but are laid over on their sides on the band. The service number on his other leg band is 2206-59866.  As of August 2016, the champion breeder has just turned 15 years old!

The second photo shows his new number one girl and the mother of the 2016 hatch year brood of 4 chicks!

Lawrence Peregrines: male perched Verizon Cell Tower

August 8, 2016 in Verizon Cell Tower

_W7I0414-001A number of the Lawrence peregrine falcons have been seen with regularity in perch mode on the Verizon Cell Tower in Lawrence.  Both the adults and the 2016 hatch year fledglings have used this as a recent perch location. The cell tower is located at the corner of Hampshire st. and Canal st. in Lawrence.  The lighting was a challenge for this image.  The temp was 87 degrees with clear skies and winds from NW at 9 miles per hour.

Lawrence Peregrines: adult on Verizon Cell Tower

_W7I8296-001The Lawrence Peregrines continue to be seen in a variety of perch locations over last few weeks.  Both adults and at least two of the 2016 hatch year fledglings have been seen on the Verizon Cell Tower on Hampshire St.  This has typically been a cold weather perch location so it was a bit of a surprise to find the falcons here!

Lawrence Peregrine: fledgling perched on Verizon Cell Tower

July 18, 2016 in 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

Lawrence Peregrine perched fledgling

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:

Lawrence Peregrines: fledgling flight maneuvers!

June 14, 2016 in Near the Clock Tower

CF2C4620-001Like a young child learning to walk, it takes a lot of time and practice for these peregrine falcon fledglings to learn how to land smoothly and gracefully.  Quite a treat to watch three of the fledglings play around on the roof atop the west wing of the New Balance factory complex on Merrimack Street in Lawrence!

It’s important to keep in mind…that all of the falcons have the “equipment” they need to fly and flapping is pure instinct.  What is the hardest part with the initial flights is getting the hang of how to use the equipment they have–how to steer, how to glide, how to lose or gain speed and altitude and otherwise maneuver.  It can be a sharp learning curve regarding landing – honing the above skills as well as figuring out what surfaces are good and easy to land on vs. not.  

And don’t forget all of the glass windows that reflects sky that can be extremely confusing to a young, inexperienced peregrine.  City environments do present unique dangers that a wilderness cliff nest may not, but the urban habitats also have their perks in the way of abundant food, warmth and people on the ground watching out for them should they happen to end up on the ground.
