Lawrence Peregrines: copulating

April 5, 2017 in Near the Clock Tower

_W7I1317-001Mating starts as many as four weeks, or more, before egg laying and continues through the process, up to several times an hour.  The male will mount the female, typically no longer then ten seconds, then he will disengage and fly off. Fertilization of an egg happens every 48 hours. After being fertilized, it takes an egg 24 hours to develop and be laid… resulting in a new egg being laid every 48 hours!  We are likely a day or two away from the first egg being laid, if it hasn’t happened all ready!

Lawrence Peregrines: around the nest box!

April 3, 2017 in On the Clock Tower

_W7I0784-001Both male and female seen this morning in and near the nest box!  Clear skies, bright sun, light winds from SW and temp around 40F.  The female was hunkered down at the outer edge of the nest box and the male, with leg band barely visible, was perched on a nearby roof edge, keeping watch on all around.

Lawrence Peregrines: female inside nest box

March 30, 2017 in In the Nest Box

_W7I9786-001The adult female and male continue to be seen and very active around the nest box but no signs of eggs laid just yet.  This is just a bit later than past seasons for the onset of eggs being laid, but other peregrine nests are also a bit late!  We’re getting much closer to the time!!

Lawrence Peregrines: pair bonding continues

March 29, 2017 in Near the Clock Tower

_W7I9069-001Lots of pair bonding continues with the male and female.  they are frequently seen in very close proximity to each other with the breeding cycle in full swing.  This morning the female was seen eating prey on one of the triangle pediment ledges above the entry to one of the New Balance buildings located at 200 Merrimack Street under dark overcast sky conditions.  The male was just to the east on one of the short steel beams just below the roof line.

Lawrence Peregrines: male resting on ledge

March 23, 2017 in Near the Clock Tower

_W7I7290-001A late afternoon visit by the Clock Tower with both peregrines in sight.  The male was seen on a window ledge along the very west wing of the New Balance Building.  These ledges are more regularly used by fledglings after first flights.  From time to time the adults will be perched on these granite ledges to be near the nest or just to be out of the wind and to soak up the warmth of the late day sun!

Lawrence Peregrines: around the Clock Tower!

March 21, 2017 in Near the Clock Tower, On the Clock Tower

_W7I6838-001The Lawrence Peregrines continue to be very active around the Clock Tower!  They perch in and near the nest box, make all kinds of aerial flight patterns, and continue with copulation activities.  Late this afternoon, discovered the female perched on a NW ledge just below the clock face, the male circling in flight, and then finally, the male landed on the outer edge of the next box.  He was good enough to provide a look at his alphanumeric leg bands for positive ID!

Lawrence Peregrines: female landing on weathervane!

March 20, 2017 in On the Clock Tower

_W7I6600-001On a late afternoon visit under sunny and very clear skies, had a nice opportunity to watch the unbanded female in flight around the Clock Tower.  She finally made a smooth landing on one of the upper struts on the weathervane.  The male was perched nearby but no move to join her.

Lawrence Peregrines: female atop smokestack!

March 20, 2017 in Peregrines at 250 Canal St.

_W7I6506-001While scanning for falcons in the area, just happened to glimpse a perched bird atop one of the old brick towering smokestacks in the 250 Canal Street building complex.  This a perch that gets much more use after fledglings have left the nest box.  Once in a while the adults perch here as well….here the female enjoys a spectacular view of the river and surrounding area!

Lawrence Peregrines: ready to drop eggs!

March 16, 2017 in Verizon Cell Tower

_W7I4804-001The sun was shining bright this morning with clear skies and moderate winds.  After a quick look around the Clock Tower, and in light of cold temps in the twenties, and lower with wind chill, made a run over to the Verizon Cell Tower.  Sure enough, up on the sixth floor ledge along the hot air exhaust vents, were both peregrines.  The female seemed to be trying to get the attention of the male, but he displayed a clear indifference. So after ten minutes of walking back and forth along the ledge, she took a powder and flew around to the east side of the building to an awning over a pair of larger vents, and perched herself in the sun and out of the wind!  Nice seeing them somewhat close together….

Lawrence Peregrines: close to home

March 13, 2017 in On the Clock Tower

_W7I3701-001It is that time of year and love is in the air with the peregrine falcons!  The Lawrence Peregrines remain near the nest box and one of the them is proximate at all times.  Made a quick visit to the Clock Tower and was happy to watch the female perched on a favorite corner.  This is a large just below the actual clock face and it is located on the NW corner of the Clock Tower.
