Visitors:17 visitors throughout the day, as the weather improved so did the number
of folks visiting the Observatory!
Weather:Hovering in the mid to low 60s all day, a chilly start to Pack's official
season start! Low clouds totally socked us in for the first couple hours,
but after that visibility wasn't too bad other than a slight haze. Light
east winds today and, accordingly, all raptors were seen to the east.
Raptor Observations:Better than anticipated given the forecast! Once the skies opened up, there
were birds here and there throughout the count. Nice to see so many Osprey
moving. 3 Turkey Vultures, 1 Red-tailed Hawk, and 1 Sharp-shinned Hawk were
also observed not actively migrating.
Non-raptor Observations:A few migrants around, with eyes on a couple Cape Mays and a possible
Magnolia Warbler.
Ruby-throated Hummingbird: 0 (15 this season)
Monarch: 5 (23 this season)
Predictions:Tomorrow morning may start wet, but with the sun poking out in the
afternoon, warmer temperatures, and a west wind there could be some birds
on the move!
On this day in Pack history:
"2008: Starting off the season with some Merlin fun. Official counter Julie
Brown (then Tilden): ""Most of the birds were high and distant but we were
rewarded with a few close sharpies and our first peregrine! Definite
highlight of the day at 14:35: We watched a juve merlin for 12
minutes..take 40 seperate dives at the owl on the pole while vocalizing. We
watched in awe as it harrassed a raven, chased a juve sharpie (also diving
at owl), perched on a nearby snag and then caught, tasted and spit out a
Monarch butterfly."""
