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!


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.



Peregrine Falcons courtship

March 19, 2015 in Verizon Cell Tower

The Peregrines are keeping it very interesting this breeding season!  The male lost his long time mate as she was sent to Tufts Wildlife and then retired from going back into the wild.  Our long time male with a distinguished breeding legacy attracted a new female friend.  She is unbounded so we are unable to know any history. They have been spending time together and appear to be ready for the breeding season.  They have been seen with some regularity around the Clock Tower and even poking around inside the nestbox.  In an odd twist, they have recently spent time perched on the Verizon Cell Tower which has never been part of the pattern this time in the breeding cycle.  They have also been spotted near the alternate nest site around 250 Canal Street.  So given that eggs should be laid any day, it will be fascinating to see if that happens and where that happens.  Had a chance to see them both perched on adjacent ledges some 25 feet apart late Thursday afternoon.  The female seemed to make every effort to get the male’s attention.  She called and called with no response.  She took off, made a loop right in front of him to get his fuller attention, and returned to her nearby perch.  The male continued with his clear indifference!  Fascinating to watch and can’t wait to see where this goes!  Stay tuned!

Peregrines seen on the Clock Tower together!

February 25, 2015 in On the Clock Tower

The clock is ticking down to the start of the peregrine breeding season.  Since the historic Lawrence matriarch female has been retired to the Tufts Wildlife Clinic, the male has attracted a new female friend.  They continue to spend lots of time together.  Initially they have been seen mostly at the Verizon Cell Tower.  Then the female started to be seen solo around the Clock Tower perch locations.  This morning she was perched on one of the ledges above the east clock face while the male was above on one of the window sills just below the base of weather vane also on the east side of the building.  Very encouraging signs as we may be less than 4 weeks away from first eggs being laid!


Peregrine male and new female friend!

February 11, 2015 in Verizon Cell Tower

What a pleasure to observe the male peregrine today with a new special female friend in close proximity, especially with Valentine’s Day closing in!!  The two peregrines seems to do a lot of looking at each other with a clear romantic buzz in the air!  They were perched in nearby ledge locations on the Verizon Cell Tower.  They moved to a series of nearby perch locations with a close eye on each other.  It sure felt like they were in some kind of courtship mode and testing each other for the willingness to make the next move.  Stay tuned and Happy Valentine’s Day!
