While on the way home, made a short stop to observe the Woburn Peregrine Falcons.  One of the regular peregrine watchers, Jill, was just departing.  She had a nice chance to watch the adult female as well as the 2016 hatch year fledgling.  They had both departed, prompting Jill to do the same.  Minutes later, storming in from the south, was the adult female.  She flew directly onto Pinnacle Rock, well above the nest ledge, and remained in place as the late day light was fading away.

Stopped by to observe the Woburn Peregrines this morning while making a run for fresh morning gingerbread muffins.   Had quite a treat to watch both female and male adult peregrines.  The sun was darting in and out with light winds.  Not much flight action but a joy to see both adults near one another!  The female was showing off her silver federal leg band on the right ankle.  The male was able to catch some early morning sunshine!

The female peregrine falcon was seen early this evening perched somewhat forward at the nest ledge.  She was showing her silver federal leg band along with just a clear look at her bi-colored black over green (32/BC) leg bands.  It was mostly cloudy with winds at 10 MPH out of the north and the temperature around 77 degrees and moderate humidity.  She remained perched for over 30 minutes with moments of eye closing drowsiness. Peregrine Falcons can sleep with one eye open, as half of their brain is alert while the other is asleep. This is called unihemispheric slow-wave sleep (USWS) and it allows the sleeping falcon to spring into action quickly from rest if a threat approaches while still being able to satisfactorily rest if no threat arises!

Made a pass by the Woburn Peregrines just before noon and observed the male peregrine falcon just resting tucked a bit inside the nest ledge.  This perch works nicely as a way to remain mostly in the shade during the middle of the hot days!

Stopped by to watch the Woburn Peregrines on the way home.  Discovered the male perched on one of the favorite rocky outcroppings to the east of the nest ledge.  It remained in place for over 20 minutes just hanging out and even napping for short stretches!

The adult male peregrine falcon also makes a regular perch to the east of the nest ledge and slightly above.  It seems like a tight spot.  This perch has a lot of whitewash streaking down over the rocks below!

Made a brief stop this morning to observe the Woburn Peregrines.  The adult male was perched at the nest ledge and enjoying the shade in what was going to be a very hot day.  The adult male has used this perch quite a bit over the past week.  It was 74 degrees at the time of the visit with clear skies and light winds from the north.

The male peregrine falcon was seen perched at the edge of the 2016 hatch year nest ledge.  this haas been a common perch location for each of the falcons since the single chick fledged weeks ago!

Made a short stop to observe the Peregrine Falcons in Woburn. The fledgling was seen in flight
while heading in SW direction towards nearby industrial building rooftop. After a long search in fading
light, finally found fledgling on edge of a rooftop. After about 25 minutes, it flew off to the east and landed
in well hidden perch on nearby utility pole cross beams.

This young peregrine fledged 3 weeks ago yesterday!
