Pack Monadnock Raptor Migration Observatory
Peterborough, New Hampshire, USA
Visitors:
57, including a class from the High Mowing school. 2014: The record is set for the most Peregrine Falcons counted in a day (12). Iain MacLeod: "Excellent day. Very quiet for first two hours then a nice push of birds. The highlight was the amazing show of Peregrines late in the day. During the last 90 minutes there was never a time when there wasn't a Peregrine visible. Two were hunting just below the lookout for an hour, then others would appear over North Pack and zip south. On four occasions I had four Peregrines in the air at once.The Merlin repeatedly strafing one of them was cool."
Weather:
Clear with light winds from the WNW for most of the day, with temps from 15-19 C. Thin clouds increased starting around noon, reaching 80% around 1500. Though there was a slight northerly component at the summit, at lower elevations the winds were mostly from the west and southwest, which may have impacted movement.
Raptor Observations:
A slow morning with nice pulses of birds in the afternoon. Several groups of 3-4 sharpies were a highlight, with a steady flow of harriers (all juveniles) toward the end of the day.
Non-raptor Observations:
Our most notable sighting of the day was an unfortunate one; a spotted lanternfly flew in and landed on our decoy owl, Gina's, pole. Attempts were made to capture it, but unfortunately it flew off and could not be relocated. A report of the observation was made to UNH's NHbugs. Other than that, a pair of towhees visited our little watering hole, some yellow-rumps and blackpolls were around, and a tiger swallowtail was observed. Blue Jays: 1/81 Monarchs: 7/487
Predictions:
Mostly sunny with winds from the north, it could be a good day!
