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!
