Folks- while participating in the Longmont CBC today my group (Dick
Pratt, Mike Freiberg, and John Barr) and I had a Chihuahuan Raven fly
right over us fairly low, calling as it went. As it approached head-
on we first thought it was another American Crow based on its size and
wing cadence, but when it opened its mouth we knew that ID was out.
As it went overhead the graduated tail was also distinctively
different than the more even-ended tail of a crow and it had longer-
looking wings. While Common Ravens' vocal repertoire can encompass
the higher, thinner sound of Chihuahuan, this bird's small size and
non-honking weapon of a bill ruled out it's more expected cousin.
We also enjoyed the distinct pleasure of poaching first a light-morph
and then a dark-morph Harlan's Hawk from the territory to our west in
the Hygiene area (the light bird at its normal line of poles along
75th south of St. Vrain Road, and the dark bird just west of the St.
Vrain River on Hygiene Road.) Interestingly, we missed seeing any
intermediates, the most common Harlan's morph wintering around here.
We also had a prolonged study of an adult light Rough-legged Hawk
north of Hwy. 66 between Table Mt. Road and 75th.
Gotta rest up now for the Boulder CBC tomorrow! Good luck to counters
wherever you are. Enjoy- Bill
