Lawrence Peregrines: roofbox seat!

March 21, 2018 in lawrence peregrines, On the Clock Tower, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_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.

Lawrence Peregrines: in the next box

March 21, 2018 in In the Nest Box, lawrence peregrines, Peregrine Falcons Massachusetts

2018.0321-001Observing the peregrines through the New Balance Falcon Cam under overcast skies, wind from NW around 3 MPH, and temp in low forties.  The female is moving around slowly with very low energy.  Some times she just sits inside the box on the gravel with little or no movement….all part of getting ready!

LETHARGY: Just before and during the period of egg laying (approximately eight days for four eggs) the female becomes lethargic. She can look “dumpy”, including fluffed-up feathers while perched, hanging her vent feathers (the feathers in front of the cloaca, underneath the tail) to an unusual degree, leaning slightly forward while perched, waddling when walking, dozing with one or both eyes closed for long periods, and generally remaining near the nest and being inactive. She might also spend considerable amounts of time in the nest by herself. After laying an egg, she may have periods of being more active, but lethargy is a general demeanor to note. Those without much previous experience with Peregrines should be aware it is comparative and subjective.

Lawrence Peregrines: rooftop

March 20, 2018 in Near the Clock Tower, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I3882-001Arrived in the Clock Tower area close to 6:15 pm and located both peregrines on the south edge of the New Balance building along Merrimack Street.  The male sat quietly without moving much.  The female was closer to the SW corner and she was cleaning her bill against the edge of the roof line!

Lawrence Peregrines: Verizon Cell Tower

March 20, 2018 in Verizon Cell Tower

_W7I3799-001Made a mid-morning visit in search of the peregrines and located the male perched on one of the exhaust vent ledges on the nearby Verizon Cell Tower.  This winter has seen the peregrines perch much later than usual at the Verizon Cell Tower, as egg laying time draws near.  Typically, in the weeks leading up to egg laying time, they stay very close to the Clock Tower, and defend their territory from all nearby intruders.  This morning the male was seen loafing in the sun at the Verizon Tower!

Lawrence Peregrines: nest box perch

March 19, 2018 in In the Nest Box, lawrence peregrines, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I3356-001Made a short visit under late day sun with adult female perched outer edge of nest box, enjoying the sun.  She has been in or near the nest box the last number of days.  She is lethargic and slow in moving around, with egg laying time very near by!

Lawrence Peregrine: Verizon Cell Tower

March 15, 2018 in Verizon Cell Tower

_W7I2308-001Had but a few moments to look for the peregrines; none at Clock Tower, so made a fast pass by the Verizon Cell Tower.  Normally, at this point in the calendar, both peregrines would be always found in and around the Clock Tower making sure their territory is well defended, and ready for the breeding season.  Not so today, with the male perched on an upper ledge at Cell Tower, under clear skies, bright sun, winds out of west close to 20MPH and gusts over 25MPH, and temps around 40F

Lawrence Peregrine: perched on ledge!

March 12, 2018 in On the Clock Tower

_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.

Peregrine Falcons: Taunton Green

March 11, 2018 in Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I1441-001Made a short visit to downtown Taunton to look for the local pair of Peregrine Falcons.  They popped up right away in flight mode over Taunton Green, and then on one of nearby buildings.  After watching a bit, the the female landed on a roof level, rounded granite post and called out to the nearby male.  A few moments later, he swooped in, and started copulation sequence.

In this instance, the male falcon mounted from flight onto female. Typically, as the male prepares to mount, the female sleeks feathers, crouches, and leans forward, and may move her tail up and to side. During copulation, the female is normally at an angle of about 45° with wings slightly lifted and extended (from elbow), sometimes tail partly spread. The male makes every effort to maintain an upright position throughout copulation by flapping wings high above body and balancing on his tarsi with closed toes and feet turned inward. During copulation, the male’s neck is extended and curved; he chitters while she gives copulatory wail.

_W7I2039-001After about ten seconds, the male departed and landed at a nearby perch, while the female remained atop the granite post, then departed and perched atop proximate rooftop

Lawrence Peregrines: pair bonding underway!

February 12, 2018 in lawrence peregrines, Near the Clock Tower, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I7077-001Made a morning run by the Clock Tower in search of the Lawrence Peregrines. Mostly cloudy, wind from NW at 9MPH, and temp around 42F.

The female was perched on the short but prominent steel beam on south side of Merrimack Street near intersection with Union Street. This is a very regular perch location in the morning, as the weather warms up.

 _W7I7129-001She was midway through a morning snack, when the male zoomed in and snatched the goodies….pair bonding underway!

Lawrence Peregrines: Verizon Cell Tower warm air vents

January 25, 2018 in Verizon Cell Tower

_W7I5963-001Made a morning sweep in search of the Lawrence Peregrines, by first passing by the Ayer Mill Clock Tower, and then onto the Verizon Cell Tower. Weather conditions: bright sun, clear skies, wind out of NW at 9MPH, and temp rising to 24F.  The Cell Tower is one of the most regular perch locations in the colder winter months due to the warm air exhaust vents on the south side of the building!
