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!

Peregrine Falcon fledgling: Verizon Tower!

August 7, 2017 in Verizon Cell Tower

_W7I3895-001While scanning for Peregrine Falcons from near the Clock Tower mid-morning, saw a perched bird on the Verizon Cell Tower on Hampshire Street and made way over for a better look.  It was cloudy and overcast, but was able to get nice looks at one of the fledglings. It had a color-coded leg band but was unable to make out the alphanumeric code.  The fledglings usually find their way over to the Cell Tower after fledging for visits from time to time!

Peregrine Falcons: East Cambridge pair

_W7I0151-001Here is a look at the female on watch at the nest box with the male nearby.  From a distance, only one chick has been visible and is close to fledge time!

Day 32: More vocal and active

June 13, 2017 in In the Nest Box

2017.0613-001By day 32, the patches of remaining down feathers are becoming restricted to the base of the legs, parts of the wings, and perhaps parts of the back, as well as the crown.  They are also becoming increasingly vocal and active around the nest area, to the extent that the adults rarely visit except to drop off food for them.  However, on days with very high heat, the female may provide protective cover in the late afternoon sun with temps over 90F!

Peregrine Falcons: Watertown

June 13, 2017 in Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

_W7I0116-001Made a visit to look at the Peregrine Falcons in Watertown.  It was just as a heat wave was subsiding and the late temp was moving down into the high 70’s.  One of the adults was seen on a ledge, on the SW corner of the building.  It was still panting from the heat and keeping it’s wings a bit spread and lifted up to keep cool.  Another adult was nearby and one chick, had fledged and was on a lower ledge beneath the nest box.

Lawrence Peregrines: ready to fledge

June 12, 2017 in In the Nest Box

_W7I9852-001During a late afternoon visit to observe the nest box action, had a wonderful opportunity to see the chicks moving around the outer ledge of the nest box.  As happens at this stage of growth, there was lots of wing flapping and movement by the chicks.

Of particular note was watching the female go out on the perch a number of times and show the chicks how to do so.  she demonstrated how to balance and not fall off.  Then she took off into flight in to the west.  As she lifted off, her talons remained out, not tucked under in normal streamline fashion.

_W7I9895-001She was making a very short flight to a nearby rooftop to show the nestlings how to prepare for first flight!  she remained on the roof for a few minutes and then took off in a flash.

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.

Day 26: More colored feathers on breast

June 7, 2017 in In the Nest Box

2017.0607-001In their fourth week of life, the chicks undergo significant changes almost daily.  Around day 25, the brown tips to the secondaries become clearly visible, and the number of coloured feathers visible on the breast increases noticeably.  Behaviourally, they are rarely resting on their tarsi anymore at this age.

At day 26, the development continues in terms of the increasing covering of juvenile feathers on the breast.  The area on the head bare of down also continues to expand.
