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.

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: 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 chase scene!

September 28, 2017 in Peregrine Falcon Woburn, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I7913-001After arrival in the general quarry area, it took a while to locate the male.  He was well hidden behind a small clump of weeds growing out of the rocks.  A number of local pigeons were active flying around the quarry.  It was partly sunny, with winds from the north at 15MPH and the temp was 73F.  Without much warning, the male launched into flight in a springboard takeoff in pursuit of the pigeons.

 

 

_W7I8040-001He made a half-hearted chase and then looped back around to land at the nest ledge!  He remained vigilant in watching the continuing pigeon flight activity!

Peregrine Falcon: Woburn adult male

August 28, 2017 in Peregrine Falcon Woburn, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I4790-001Monday morning visit to quarry with sighting of perched adult male nestled on a ledge, in the shade, with no activity.  As always, many pigeons in flight nearby, but no other birds or hawks that might  have prompted falcon into flight.  Mostly sunny conditions with little wind and temps in low 60’s.

Peregrine Falcon: Woburn adult male

August 7, 2017 in Peregrine Falcon Woburn, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I3824-001During a short brief visit to the Woburn Peregrines this morning, discovered the male well hidden behind one of the rocky outcroppings. On some visits, it takes some added time to find one of the adults as they tend to blend in so well with little movement!  Here he was just barely visible!

Peregrine Falcon: Woburn female

August 3, 2017 in Peregrine Falcon Woburn, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I3796-001A nice mid-afternoon visit to the Woburn Peregrines with nice looks at the female in the midst of a right leg stretch!  The sun had ducked behind the west quarry wall but the overall lighting was till fairly good.  she was perched on one of her favorite tree branch perch locations with no other activity going on in the general area.  She appears to have a full crop after a likely recent meal.
