Subject: Re: [LACoBirds] Evening Grosbeak flyover + Irruptions
Greetings Everyone, Grigory's audio recording definitely shows type 1
evening grosbeak flight calls. They look very similar to the ones
Norm Vargas reported at Mt. Wilson Observatory yesterday. The area
in question is east of the locked gate at about mile 54 on the Angeles
Crest Highway, and it has actually seen quite a bit of coverage by
birders this year. Clark's nutcrackers have been present in modest
numbers all summer and have seemed more reliable there than usual. The
elevation at the gate is around 6200-6300 feet and is usually about as
low in elevation as nutcrackers regularly occur in the area. Most of
us visiting the area have walked a mile or two past the locked gate
and used the mile 55.44 eBird hotspot for our bird lists. Given that
places like Cloud Burst Summit, Buckhorn, Eagle's Roost, and Islip
Saddle aren't accessible to cars due to the road closure, you can
still park at the gate at mile 54 and walk east along the road or
along the Pacific Crest Trail. Right now this provides the easiest
access to high elevations on the west side of the Crest. If you visit
during weekdays there might be construction crews on the road but on
weekends there's much less activity and you might encounter only a few
hikers. If you're feeling especially intrepid, it's still possible to
walk along the highway to Cloud Burst Summit (about 3 miles, with ~700
feet of elevation gain) or to the Buckhorn area (~4 miles to the
entrance, 5 miles to the exit). Note that the entrance road into
Buckhorn has multiple deep and wide washouts, so I recommend going in
along the exit road, which is in good condition. Regards, Lance Lance

Subject: [LACoBirds] Evening Grosbeak flyover + Irruptions Hi all, I
spent some time this morning checking out various points along the 2
in the San Gabriels looking for pinyon jays and other irruption
species. After walking a few miles around Chilao campground (no
notable sightings, although Lawrence's goldfinches are always a
welcome surprise) I decided to check out an area up the road I don't
think has been covered recently and walked out behind the road closure
at the 6000' gate a bit. Walking the highway right above Glenwood
camp, I heard an Evening Grosbeak flying over heading south -
spectrogram looks like the expected Type 1 to me but I'm no expert on
these: https://ebird.org/checklist/S395599787. I also had two Clark's
nutcrackers flying south here, although at this elevation it's not too
out of range for nutcrackers. This stretch of closed road is right
above a large canyon and may be good for funneling birds heading south
over the ridge.

Stopping by Chilao visitor center on the way back, I briefly heard a
single pinyon jay.
