Peregrine Falcons: Watertown

While heading home, had a nice opportunity to check on the Peregrine Falcons in Watertown.  This is a known nesting pair that have been in residence the last few years.  It was mostly sunny, with east winds  at 10MPH, and temp at 60F. The adult male was seen on the front of the building in […]

Lawrence Peregrines: preening and rousing

Made a late afternoon visit to the Clock Tower under clear skies, bright late day sun, light winds from the SE, and temp at 64F.  The adult male had just returned to a ledge on the NW corner below the clock face. One thing the peregrine falcon does a lot is preening. Many hours each […]

Peregrine Falcon: Woburn male

A Monday morning flyby visit with clear skies, bright sun, winds from NW at 5MPH, and temp at 63F.  The adult male was perched on the nest ledge and preening with its bill.  Preening keeps the feathers neat, preserving their streamlining and insulating effects as well as their color pattern.  Preening may help to remove […]

Peregrine Falcon: Woburn chase scene!

After arrival in the general quarry area, it took a while to locate the male.  He was well hidden behind a small clump of weeds growing out of the rocks.  A number of local pigeons were active flying around the quarry.  It was partly sunny, with winds from the north at 15MPH and the temp […]

Lawrence Peregrines: adult male on upper ledge

Made 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 […]

Peregrine Falcon: Woburn adult male

Monday morning visit to quarry with sighting of perched adult male nestled on a ledge, in the shade, with no activity.  As always, many pigeons in flight nearby, but no other birds or hawks that might  have prompted falcon into flight.  Mostly sunny conditions with little wind and temps in low 60’s.

2 Bald Eagle adults and 1 fledgling!

Had a nice chance to observe two adult Bald Eagles and a fledgling this morning, along the Merrimack River in Essex County. The fledgling leaped up into flight from rocks along the river bed. It then hopped from one perch to another and then remained in place for a while under overcast skies, light rain, […]

    Hi, Craig! This site is spectacular! I am working with the 21 st Century program at the Wetherbee School doing a river study of the Merrimack. We took our students on their first barge ride yesterday up river and saw a red tail chasing a great blue heron, many hawks, geese, mallards, and other birds. A rainbow on the way back. I had no idea there were kestrels in the area, nor did I know of the peregrines. My brother ( Craig, also!) has a live video feed of a nest at the top of the Marriott in Boston. I’m wondering if you had time to come share your knowledge with our 3 rd and
    4 th graders at the Wetherbee some day after school? If not, I’ll have them blog you on this site. Btw. I live in a lake in Tyngsboro and witnesses a pair if swans harassing some Canada geese this morning. Can they move! I could go on and on about our wildlife, but that’s for another day. Can’t wait to visit the rookery in NA. Thanks again for your site. Kate Oliver
