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 Falcons: Woburn pair

November 15, 2017 in Peregrine Falcon Woburn

_W7I7170-001A beautiful morning with clear skies, bright sun and light winds!  Both adult peregrines continue to be seen most days around the quarry area.  This morning the male was perched at the front edge of the nest ledge with the female nearby.  She departed in pursuit of a passing hawk and then promptly returned, likely after engaging in a little territorial defense.  She returned to a regular perch atop Pinnacle Rock.

Peregrine Falcons: Woburn pair on pole

November 12, 2017 in Peregrine Falcon Woburn

_W7I6964-001Made a visit to the Peregrine Falcons in Woburn on sunny Sunday afternoon.  Discovered both adults perched on the double cross bar utility pole located on the south side of the main parking lot.  It was a beautiful afternoon with bright light, little wind and temps in middle 40’s.  Had a nice opportunity to pause for closer looks at the female as she was resting with a full crop after a recent meal.

_W7I6964-002Took a moment to observe and appreciate the nostril cone; falcons have a cone (baffle) just inside each nostril that disrupts the air flow and reduces the pressure of the air entering the respiratory system…also a nice look at the tomial tooth, known as the “killing tooth.” It is a notch on the cutting edge of the upper beak that is used to sever the prey’s spinal column.

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 Falcon: Woburn male

_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.

Peregrine Falcon: Woburn chase scene!

_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.

Peregrine Falcon: Woburn female perched

June 12, 2017 in Peregrine Falcon Woburn

_W7I0073-001The heat wave continues and the local peregrines can be seen panting and holding their wings out and up a bit to stay cool.  The female was the only one seen today and she was perched in the late day shadows atop a utility pole near the circle.
