Hi, When I left work on Friday afternoon (Dec. 18) and approached my car in the parking lot on the edge of the Bethesda business district, I saw a bird sitting on top of a delivery truck about 50 feet from my car, in another row of the parking lot (near the edge of said lot). I quickly realized that it was a big accipiter. Approaching closely and carefully, I strained to see colors on the back and belly. I finally convinced myself that the underparts had some, red, barring. I came closer, but did not want to scare the bird. Then I realized I had to put money in the meter, as I had an errand yet to run before I went home. After I dealt with the meter matter, I approached the truck from a different angle, and then stopped about 30-35 feet from the bird. I could now clearly see red barring as well as a cap darker than the nape. Someone coming to her car asked if I always stopped while walking around in parking lots. I showed her the bird and told her that I never expected to see an adult (presumed female) Cooper's Hawk perched on top of a delivery truck in a fairly built up area with little tree cover nearby, eating its prey. At some point a person walked up the sidewalk toward the bird, got in his car, and drove off. The bird barely paused from plucking feathers. I was not able to tell what species of bird had been caught. I went to a nearby coffee shop where I had recently seen a coworker, but when I returned, he was not there. I walked back, quickly, to the parking lot, and noted a House Sparrow wing on the sidewalk (not necessarily from the Cooper's Hawk, but who knows?). As I crossed the street I saw the hawk on a light fixture, and watched as it took off, seemingly with its meal in its clutches, and fly in to the residential area. This morning as I got out of my car in the same parking lot, a fairly hefty sized Accipter flew 20 or 25 feet past my car, about 20 feet above the ground, and toward the Bethesda Bagels and Giant supermarket, and out of sight. Seconds later two knots of starlings boiled up from that area and flew in my direction. I assume that this is the same bird. Between my surprise and the overcast conditions, all I saw of it was its outline. Rob
