Re: [cobirds] Boulder raven antics

I would not have mentioned this, but I thought it would make an interesting piggy-back on Elena's comments.  Ted Cooper and I did a trip yesterday that started at Red Rocks, and wound its way from Baseline to Legion Park, on to Cottonwood Marsh and 75th Street, over to the "cardinal site", up to Allenspark, back through Ward and finally ending at Valmont for a very interesting "gull hour" with Ted Floyd.  We saw lots of great birds along the way, but nothing worthy of posting that hadn't been previously mentioned by Mike Henwood and Ted.  However, as we were driving up to the cardinal locality, we were stopped at an intersection when we saw a pigeon behaving strangely; it was flying into a corner formed by the intersection of two buildings and seemed to be in a total panic.  The source of the pigeon's distress quickly became apparent.  Two ravens were pursuing the bird into the corner with obvious evil intent.  They harrassed it into a collision with a door and through several (for a pigeon) fairly impressive aerial maneuvers. The pigeon ultimately escaped, and I commented that I had never seen ravens acting like raptors.  They did not have the skills to bring down the pigeon, but it was not for lack of trying.

Subject: [cobirds] Boulder raven antics

Yesterday at the 29th Street Mall in Boulder, a pair of common ravens was   perched in the roof trusses of the roof over the parking garage.  Their   vocalizations were tremendously amplified, resonating through the garage and the   walkway.   They weren't feeding on anything, just sitting and calling.  We   traded a number of resonant "quorks" and I would have stayed to see what they   were going to do but had an appointment at the Apple store. Then today at 1 pm a   raven chased a red tailed hawk over Valmont and 28th street, both zigzagging   pretty low over the traffic.
