Lawrence Peregrines: one juvenile and two adults!

August 27, 2018 in lawrence peregrines, On the Clock Tower

_W7I9090-001What a nice surprise to see one of the 2018 hatch year fledglings around the Clock Tower late this afternoon.  It was another steamy hot day with clear skies, light winds, and temp well over 90F.  Just happened to catch a glimpse of a peregrine and upon a close look, it was one of the this year’s youngsters perched on the west side pole of the weathervane.  The left leg band was visible but just out of reach for a positive identification.  One the adults was seen on the SE corner of the lower roof, and the other was perched high atop the Verizon Cell Tower over the Merrimack River!

Clock Tower: fledgling off balance!

_W7I7575-001Made a visit to the Clock Tower later this afternoon under clear skies, bright sun, wind from SW at 12MPH, and temp at 94F.  Both adults were seen perched and in flight around the Clock Tower.  One of the juveniles was perched for a while on the rood below the weathervane, and then launched into flight, circled a few times, and then landed on the nest box perch pole.

 

 

_W7I7564-002It was a bit challenged maintaining balance, and tuned around a few times.  Then, when ready to depart, it made a few awkward steps and lost its balance, falling into flight! Amusing to watch and a reminder that the youngsters are still learning their flight and safe landing lessons!

_W7I3959-001While driving over the Duck Bridge, heading south, noticed one of the peregrines looping flight around the NW corner of the Clock Tower.  It landed out of sight.  Once around to the west side of the tower, looked around for a few minutes before finding the female up very high, on a perch ledge, outside of a vented window box.  The ledge is just below the weather vane.

_W7I2288-001Another morning visit to the Lawrence Peregrines at the Ayer Mill Clock Tower, under clear skies, bright sun, wind out of north at 8MPH, and temp just above 30F.  Observed both peregrines loafing on upper level perches on the west side of the Tower.  One of them flew off while the other remained on a ledge above and to the left of the west side clock face.

Lawrence Peregrines: pair around Clock Tower

November 15, 2017 in On the Clock Tower

_W7I7433-001Both adult peregrines have been lounging around the Clock Tower in recent days.  This is very normal for this time of year, as it is important to maintain territorial defense around the nest box.  This morning the female was seen on an upper ledge on the west side of the Clock Tower.  This has been a regular morning perch location.  The male was found around the corner on a short protruding steel beam just below the roof line on the south side of the mill complex along Merrimack Street.  It is a prime spot to bask in the morning sun and out of the wind!

Lawrence Peregrines: preening and rousing

October 3, 2017 in On the Clock Tower

Made a late afternoon visit to the Clock Tower under clear skies, bright late day sun, light winds from the SE, and temp at 64F.  The adult male had just returned to a ledge on the NW corner below the clock face.

_W7I9115-001One thing the peregrine falcon does a lot is preening. Many hours each day is spent on the care of feathers, beak, cere and feet. Sometimes it seems like pure vanity, but it is in fact a necessity. Without well preened feathers the peregrine could become soaking wet when it rains, become ill and die. Or feathers that are not well groomed will cause drag when flying. When preening birds run their beaks through their feathers or scratching their heads with a toe.

_W7I9106-001Rousing is the the action of a peregrine erecting its feathers and then shaking them; part of grooming; a sign of a relaxed and content bird. Peregrines typically rouse (shake) after preening; also rouse during flight, particularly after leaving perch (unless to initiate a pursuit).

Lawrence Peregrines: adult male on upper ledge

August 28, 2017 in On the Clock Tower

_W7I4799-001Made a short visit to the Clock Tower with little to see upon arrival.  A few passing gulls and Double-crested Cormorants in flight over the Merrimack River.  Then a bolt of speed came in from the NW with a definitive flight pattern that could only belong to a peregrine.  Sure enough, the adult male arrived and with legs outstretched, landed on an upper ledge, above the west clock face, and in the shade.

Two Peregrine adults and one fledgling at Clock Tower

August 14, 2017 in On the Clock Tower

_W7I4114-001The 2017 hatch year fledglings made first flight almost 8 weeks ago.  Three of the fledglings have been seen regularly around the Clock Tower.  The first fledgling left and has not been seen since fledging.  At this stage of growth, parents provide two important things to the young falcons: predator protection as well as food supply.  Here, the adult female remains on guard for any predator threats.

 

 

_W7I4144-001The protection continues, but the food supply, as provided by the parents, begins to dwindle as they improve their ability to chase and capture prey.  The falcon experts suggest that most young peregrine falcons disperse on their own once they have become proficient at killing on their own.  This young peregrine may be the only one left around the natal site!

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!

Lawrence Peregrine Falcons: female ready to land!

April 10, 2017 in On the Clock Tower

_W7I4126-001Made a later afternoon visit to the west side of the Clock Tower and found the female in flight and landing mode a number of times around the NW corner of the below the clock face.  The skies were clear with bright late day sun, light winds front he SW, and temps just below 50F.  No doubt the female is stretching her wings after hours incubating 4 eggs!
