Lawrence Peregrines: almost a week!

April 11, 2019 in In the Nest Box, lawrence peregrines

Had a nice opportunity to watch the female in the nest box this morning.  Just before 7AM, she raised herself up a bit and changed positions but remained over the 4 eggs.  Then at 7:07AM, she departed for a few minutes and returned to the box, and then back to incubating the eggs. During incubation, an observer may spend lots of time watching very little activity.  The peregrines take turns brooding the eggs. Typically, the female incubates about 2/3 of the time, often for four or more hours before the male relieves her. Males brood for shorter periods– typically 2 to 3 hours, and they brood less frequently. While one adult is brooding, the other may be out hunting. Brooding falcons still need to eat, after all. If they’re not hunting, the other falcon usually stays close to the nest.  The photo on the left shows the female sitting on eggs quietly and with great comfort.  She will adjust as she needs to but is not fidgety as the male tends to be!

Sometimes while the female is brooding the eggs, the male will bring her food that he has hunted. She’ll eat the food, sometimes inside, and other times, outside the nest box while he takes a turn incubating, but then she’ll come back and take over– provided she can get him to move off the eggs. If he doesn’t move right away, she may stand in the nest box and wail at him. Wailing has different meanings for falcons, but in general it indicates dissatisfaction with the current situation.  Here they are together, inside the nest box at around 10:35 AM today, and she is wailing on him big time.

IMG_9571So if this female wails at her guy while he’s incubating, or in the nest box it’s her way of telling him she’s not happy that he’s still standing around, or sitting on the eggs. As with most other interactions between male and female peregrines, the female usually gets her way, though sometimes it takes a while for him to get the message!  Guess who’s usually walking away, with his head bowed low, after getting wailed at….the male!

Lawrence Peregrines: Egg #4!

April 5, 2019 in In the Nest Box, lawrence peregrines

2019.0405-001Checked on the nest box just after 6AM this morning under fair skies, wind from west at 9MPH, and temp at 31F. The forecast for today calls for mostly cloudy skies, with a high near 47. Light and variable winds becoming south 5 to 9 mph in the afternoon. For tonight, rain and snow likely before 1am, then rain. Low around 36. South wind 6 to 8 mph. Little or no snow accumulation expected.

After waiting almost an hour for a look this morning, the adults had a shift change at 6:53AM and this provided a quick peek at the 4th egg!  This egg was likely laid at some point overnight.  Had kept a close eye early evening last night and had a clear sighting of just 3 eggs just before sunset, with little egg laying movement seen up until dark settled in.

So now, the Peregrines shift into full and shared incubation duties that will last the next 30 days or so!  We are about a week ahead of last year’s egg laying time frame. With God’s grace the circle of life continues!

Lawrence Peregrines: Egg #2!

March 31, 2019 in In the Nest Box, lawrence peregrines

The morning started off under mostly cloudy skies, wind from the south at 12MPH and gusts up to 23MPH, and temp at a balmy 57F.  The forecast calls for showers, mainly after 1pm. High near 63. South wind 11 to 16 mph, with gusts as high as 31 mph. Chance of precipitation is 80%. New precipitation amounts between a tenth and quarter of an inch possible.

2019.0331The female was observed inside the nest box just after 7AM this morning, both standing over the first egg and then nestled down lower in incubation mode.  She constantly looked around and also vocalized a bit at times. The wind circulated just enough inside the nest box to move her feathers around while she incubated the egg.  In prior years, the first egg would be left for longer periods unattended, but this year seems to be getting more active attention.  As an observer, you may have to keep watching for a while until she lifts up off the egg and takes a break!

Checked back in later in the afternoon and the second egg had yet to appear and then checked back just before 6PM and the second egg was seen when she lifted up for a few moments and took off for a bathroom break! We’ll look for the next egg to be laid, hopefully on Tuesday afternoon!

Lawrence Peregrines: first egg!

March 29, 2019 in In the Nest Box, lawrence peregrines, Peregrine Falcons Eastern Massachusetts, Peregrine Falcons Massachusetts

After many visits in and around the Clock Tower and many looks through the web cam, including earlier today, what a nice surprise to check in this afternoon and find the first egg laid for 2019!

2019.0329.LP

Finally after waiting and waiting, the female laid her first egg this today!. Her behavior was very consistent with the general lethargy that a female falcon typically experiences in the few days prior to laying the first egg. In many cases this lethargy may last a week or longer. She lazes around and spends lots of time in the nest box, nest scraping, and other courtship related activities.

Incubation usually will not begin until the second to last egg has been laid. In this cool spring weather, with night time temps in the low 30’s, the female will spend some time incubating the egg, but it may not be a non-stop effort!

The female has a silver federal leg band on her right leg; and a black over green 38/BV band on her left leg.  The male has only a silver right leg band and no band on his left leg.

Peregrines: both adults

August 28, 2018 in lawrence peregrines, Near the Clock Tower

_W7I9324-001Made a stop by the Clock Tower just before 10AM, under clear skies, bright sun, winds from the west at 8MPH, and temp at 86F, to look for any peregrine activity.  The adult male was observed on the south side of the New Balance building along Merrimack Street.  Initially, the male was perched along the roof line, and then it flew around to a number of perches and then flew around towards the nest box.

 

 

_W7I9532-001The female was spotted along the the same south side roof line.  She was very bust consuming a snack and feathers were flying all around.  Had a nice view as she was finishing off the pink legs of her fresh catch.  Nice to see both adults in close proximity!

Lawrence Peregrines: one juvenile and two adults!

August 27, 2018 in lawrence peregrines, On the Clock Tower

_W7I9090-001What a nice surprise to see one of the 2018 hatch year fledglings around the Clock Tower late this afternoon.  It was another steamy hot day with clear skies, light winds, and temp well over 90F.  Just happened to catch a glimpse of a peregrine and upon a close look, it was one of the this year’s youngsters perched on the west side pole of the weathervane.  The left leg band was visible but just out of reach for a positive identification.  One the adults was seen on the SE corner of the lower roof, and the other was perched high atop the Verizon Cell Tower over the Merrimack River!

Male perched on grate SW corner

August 15, 2018 in lawrence peregrines

_W7I8568-001Made a pass by the Clock Tower yesterday afternoon on the lookout for some of the peregrine falcons.  One of the adults was perched on one of the granite ledges on the NW corner. It departed in flight for a few moments, and then returned and landed onto the metal grates on the SW corner of the upper roof.

 

_W7I8549-001After a few adjustments, and a bit of wing flapping to maintain balance, the male adult, turned around and faced in outward direction.  The movement provided clear looks at legs and banding, and from that, an ability to see clearly that it was the adult male.  The female has been seen from time to time, but the youngsters have not been around these past few weeks, and may have dispersed early.  Will provide an update next few days on research on the varied dispersal patterns of fledglings!

Fledgling in flight; adult female perched nearby!

_W7I8274-001Made a visit to the Clock Tower this afternoon under mostly cloudy skies, winds from SW at 10MPH, and temp at 94F.  Very little action around the area.  With binocs, made a scan and observed one young falcon atop the tall smokestack on opposite side of the Merrimack River by 250 Canal Street complex.  Then, made a closer look at the distant Verizon Cell Tower at the corner of Hampshire and Canal Streets.  The adult female was perched on the east side of the cell tower on a lower cross bar.  Her black/green leg band was barely visible.

_W7I8326-001One of the juveniles was perched up much higher on the north side of the Cell Tower.  Moved around to the west side of the Tower for a better look with just a bit more light.  The young falcon spread its wings and departed in a downward stoop in pursuit of something just out of sight and returned a few minutes later.  It then made many loops in flight around the tower and landed.

Clock Tower: fledgling off balance!

_W7I7575-001Made a visit to the Clock Tower later this afternoon under clear skies, bright sun, wind from SW at 12MPH, and temp at 94F.  Both adults were seen perched and in flight around the Clock Tower.  One of the juveniles was perched for a while on the rood below the weathervane, and then launched into flight, circled a few times, and then landed on the nest box perch pole.

 

 

_W7I7564-002It was a bit challenged maintaining balance, and tuned around a few times.  Then, when ready to depart, it made a few awkward steps and lost its balance, falling into flight! Amusing to watch and a reminder that the youngsters are still learning their flight and safe landing lessons!

Fledglings eating on ledge

July 3, 2018 in Near the Clock Tower

_W7I6334-001Made a stop by the Clock Tower on Tuesday morning at 8:45AM under bright sun and clear skies, winds from the W at 6MPH and temp at. 84F.  The female was perched on the nest box perch pole.  This strongly suggested that the fledglings were close by.  Sure enough, one of them, 27/BU was picking apart a morning meal on an upper story, west facing ledge, of the New Balance building, not far from the Merrimack Street entrance.  Another youngster was above a much higher ledge above the clock face.

 

 

_W7I6756-001The fledgling eating prey, was ripping it apart and not wasting a minute.  The other, slightly larger fledgling, 29/BU was content to just watch.  It may have eaten a bit earlier.  They then sat next to each other for a bit before the larger one took off in flight.  Observed all three fledglings, as well as both adults; very nice to see the young family all together!
