Peregrine Falcon pair: Boston University

December 7, 2017 in Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I1630-002Made a short visit to Boston University this morning to look for the resident pair of peregrine falcons.  This pair of adult peregrine falcons were seen basking in the glow of the rising sun on the east side of the building, high atop 26-story StuVi II at Boston University!  Due to the distance, no ability to observe leg bands for more detailed information.

Peregrine Falcon: Woburn – bulging crop

December 6, 2017 in Peregrine Falcon Woburn, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I1470-001Made a short visit to search for the peregrines in Woburn under mostly cloudy skies, wind blowing from the west at 16MPH with gusts over 20MPH.  Observed the adult female falcon on a perch to the left of the nest ledge.  Great looks at the female with a very full crop. The crop is the name of the part of the falcon’s anatomy that serves as a storage area for food until it is passed to the stomach – often seen as a bulge in the upper part of the bird’s chest area when it is full.

Peregrine Falcon pair: Downtown Haverhill

December 4, 2017 in Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Haverhill, Peregrine Falcons Massachusetts

_W7I0581-001Pair of Peregrine Falcons on the weathervane at the Post Office in downtown Haverhill. This adult pair was first discovered by Steve and Jane Mirick.  They were not successful in breeding attempts in 2016.  The male is perched atop the weathervane with the female below to the left. 

They both departed in pursuit of prey and returned a short time late. They were observed under bright sun and clear skies with little wind and temps in low thirties.  This pair has not been sighted for the last few months, so this is a welcome sighting and a promising sign of continued pair bonding!

_W7I0900-001The male provided nice looks at his leg bands.  The alpha-numeric black over green left leg bands showed 72/AB.  According to Chris martin at NH Audubon, this was a 2012 hatch year chick, 1 of 2 banded at Brady-Sullivan Tower in Manchester NH on 5/10/2012.

Lawrence Peregrines: Verizon Cell Tower!

November 10, 2017 in Peregrine Falcons Eastern Massachusetts, Verizon Cell Tower

_W7I6768-001As the late fall temperatures drop below 30 degrees, the Peregrines start to spend more time at the nearby Verizon Cell Tower near the corner of Hampshire and Canal Streets.  They tend to perch on the fifth and sixth floor ledges located on the south side of the building.  These ledges are next to hot air exhaust vents.  These vents provide excellent heat during the colder months.

Found both adults happily perched near one another on sixth floor ledges in late afternoon.

Peregrine Falcons: Woburn preening

November 1, 2017 in Peregrine Falcon Woburn, Peregrine Falcons Eastern Massachusetts

_W7I6421-001Had a nice visit to Woburn quarry this morning under sunny skies, calm wind conditions, and temps in high 30’s.  Both adult peregrines were seen perched in regular locations on the quarry wall.  Lots of time was dedicated to scratching, preening, and vocalizing. Peregrines say “ee-chup” when they are looking at another peregrine.  They say it softly to their mates during ledge displays and more loudly when a new peregrine shows up.   The new peregrine may be an intruder or a potential mate.  It takes a lot of practice, listening and watching from the ground, to be able to tell whether an ee-chup means “Hello, my love” or “I see you, Intruder!”   Unless you can see both peregrines having the conversation, don’t assume you know what ee-chup means.  This morning, they were just expressing fondness towards each other!

Peregrine pair: Boston University Towers

October 19, 2017 in Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I1699-001Had a nice early morning visit to the Student Village high rise buildings on the Boston University campus this morning.  With clear skies and bright sun, had nice looks at the resident pair of peregrine falcons that make their home atop the 26-story StuVi II.  They were active around the tower and then settled in around the nest box.  The falcons maintain a variety of regular perch locations around the extended complex of nearby buildings.  Sightings of both peregrines are frequently made from a distance, at Magazine Beach in Cambridge on the opposite side of the Charles River.

CF2C2683-002According to Tom French at MassWildlife, the BU male has a left leg band with 12/BD black over green, banded as a chick in 2013 on the Newark Paper Company in a renovated mill building at 250 Canal Street, Lawrence.   On the left, is a file photo of this same bird as a hatch year fledgling, getting ready to make first flight.  The image was taken on June 4, 2013 from a rooftop in a complex of mill buildings in Lawrence, MA.

Peregrine Falcon: Albany St., Boston, MA

October 15, 2017 in Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I0923-001This female peregrine falcon was first observed while it was circling in flight over the access road off of SE Expressway while I was driving north.  With a little bit of extra time in the schedule, was thankfully able to divert and search the local area around Albany Street.  It was quite a treat to discover the perched falcon on a building security camera at the corner of the rooftop level! The seven story building is occupied National Emerging Infectious Diseases Laboratories (NEIDL) located at 620 Albany Street.  The peregrine was seen from outside the tight security fence surrounding the building.

It was a nice afternoon under partly sunny skies, Wind: SW 14MPH, 72F.

_W7I0958-001

This is the resident female from the Christian Science Church administration building at 177 Huntington Avenue. Captured at nest on 05-24-17 by Norm Smith with a hand net and banded as an “After Second Year” (ASY) female – 1947-35707, and 05/BV black over green leg band on the left leg.

Peregrine Falcons: Taunton Green

October 15, 2017 in Peregrine Falcons Eastern Massachusetts

_W7I0376-001The pair of Peregrine Falcons in downtown Taunton remain close to each other in the off season.  On most visits, it is easy to locate and observe both adults from Taunton Green and other nearby vantage points.  They remain active and engage in territorial defense of their home territory.  After arrival, the male was found perched atop one of the granite turrets on the Courthouse and launched into flight mode.  Soon after, the female landed on an upper granite ledge and extended her left leg just enough to allow positive ID of her left leg color-coded band.

Here is male launching into flight mode!

_W7I0584-001The black/green left leg band revealed the alphanumeric code: 64/V; Banding date and location: May 20, 2008, NY, Long Island, Nassau Co., East Meadow, Nassau University Medical Center.

 

Peregrine Falcons: Watertown

October 8, 2017 in Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

While heading home, had a nice opportunity to check on the Peregrine Falcons in Watertown.  This is a known nesting pair that have been in residence the last few years.  It was mostly sunny, with east winds  at 10MPH, and temp at 60F.

_W7I8759-001The adult male was seen on the front of the building in great light.  It was  stretching and preening.  Adults commonly stretch single leg or wing laterally; stand on one leg and stretch opposite leg back to side, simultaneously stretching wing from same side across extended leg. Peregrines also double-wing stretch (warble), bird bends forward and down raising both wings over back, sometimes fully extending wings at wrist; seen more in fledglings; may be followed by wing-flapping.

_W7I8953-001The larger female was seen nearby at a higher elevation near the nest box.  She then departed, made two aerial loops, and landed near the male at same elevation 8-10 feet away.  She proceeded to communicate with the male with head bowing and other movements.  In this display, her approach was entirely horizontal (head, body, and tail all in one plane) with a slight lowering of her head.  Her bill was pointed at the male and not towards the ledge. She paused to look at the male infrequently.  Fascinating to watch!

Peregrine Falcon: Woburn male

October 2, 2017 in Peregrine Falcon Woburn, Peregrine Falcons Eastern Massachusetts

_W7I8655-001A Monday morning flyby visit with clear skies, bright sun, winds from NW at 5MPH, and temp at 63F.  The adult male was perched on the nest ledge and preening with its bill.  Preening keeps the feathers neat, preserving their streamlining and insulating effects as well as their color pattern.  Preening may help to remove any possible external parasites.
