[cobirds] Cooper's Hawk
My non-birding neighbors have been telling me for several days that a hawk has been sitting in a tree in my front and side yards. Well, I finally saw it-- a Cooper's Hawk currently sitting in the maple tree by my back patio. I hope the thrush and sparrow got out in one piece!

[cobirds] Cooper's Hawk after an ECDO
Birders, This am I saw something that did my heart good. A Cooper's Hawk was chasing an Eurasian Collared-Dove. Maybe she'll get it next time.

RE: [cobirds] Cooper's Hawk after an ECDO
A bunch of years ago I found a collared-dove being mantled by a female Sharp-shinned Hawk in the Panhandle of Texas. I never saw what the end result was, but the Sharpie was riding the dove like a bull rider through the neighborhood the last I saw it. It couldn't pick it off the ground.

[cobirds] Cooper's Hawk caching food? El Paso
Hey, CoBirders, The past 2 days I've at least 1, likely 2 adult (paired?) Cooper's Hawks in the backyard partially consuming & possibly caching the remains of pigeon(s). I looked up “Cooper’s Hawk” in Cornell Lab’s *Birds of the World* website and found this under Diet: “*During breeding season, both sexes cache uneaten prey on horizontal branches and retrieve it for themselves and their young; caching may be as frequent as 1/d for females with nestlings (RNR, JB; J. Papp, personal communication). No information on caching outside the breeding season.*” Whether a true form of caching (outside the breeding season) or not, this was a fascinating series of events to me. Has anyone else observed a Cooper’s coming back for seconds from a partially hidden previous day’s kill--or even needing to eat a half-pigeon less than 24 hours after doing the same? For the detailed story and some of the gory pictures, you can see my 2 eBird submissions for 2/27 & 2/28 here: https://ebird.org/checklist/S103948453 https://ebird.org/checklist/S103966642 Good birding!

[cobirds] Cooper's hawk and chick Palmer Lake (pictures)
I have been watching this nest for a few weeks and got some good shots today. Not a rarity but fun to see, Cooper's hawk chick: http://avoapples.com/birds/IMG_0592_cr.jpg One of the parents: http://avoapples.com/birds/IMG_0860_b_cr.jpg Bill Kosar bill_ko...@msn.com Colorado Springs -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Cooper's Hawk in Denver County, possibly nestbuilding
Hello, Today while in Denver, I spotted an adult Cooper's Hawk gathering sticks below a small group of tall spruce trees in the Park Hill neighborhood a few blocks east of the Denver Museum of Nature & Science. She then flew up into one of the trees, hopping upward from limb to limb until she reached a dense place along an upper branch, which looked to me to be a nest site. I watched for about 15 minutes as she fussed around this area, presumably arranging nesting material. I say she because, looking around in the other trees, I spotted a much smaller Cooper's perched about 10 feet away -- presumably a male. It was interesting to see the difference in size between the two. I read in the first Colorado Breeding Bird Atlas book that Cooper's females are up to 1/3 larger than males (a greater difference than other hawk species), and this fit with what I observed. The difference was much greater than in the pair of Kestrels that nest near my house and the Bald Eagles I used to watch at Barr Lake. Until now, I've not seen this fact mentioned -- my field guides don't touch on it. The Atlas II manual gives a safe date of April 1, so I guess these birds are right on time. I showed the hawks to the homeowner, who was really pleased to have hawks nesting in his front yard. I've seen Cooper's in that neighborhood several times in the past two years but didn't realize they nested in residential areas.

[cobirds] Cooper's Hawk pairs at Ken Caryl Ranch, JeffCo
Some in-progress observations on the apparent number of pairs of Cooper's Hawks at Ken Caryl Ranch... Over recent weeks I've been able to make focused and casual observations in many parts of the developed area of Ken Caryl Ranch (inclusive of the "Plains" east of C470 and the hogbacks, the "Valley" west of the hogbacks and generally south of Ken Caryl Drive, and "North Ranch" west of the hogbacks and north of Ken Caryl Drive.) So far I have observed what I think are 10 different pairs on territory in the Ranch: 4 in the Valley, 2 in North Ranch, and 4 in the Plains. This seems like a pretty robust population to me. They seem more common in the developed areas of the Ranch property (which includes some open space corridors) than in the undeveloped open space areas of forest, oaks, scrub and grassland.

[cobirds] Cooper's Hawk takes Northern Saw-whet Owl, JeffCo
This was one of those unexpected encounters that went by way faster than I would have liked. This evening I walked down along Massey Draw near my home. I was within a tight stand of cottonwoods and as I looked up I saw an adult *Nor. Saw-whet Owl* looking back at me! It was perched in one of the trees in a somewhat open position overhead, about 30 feet above the ground. But then less than 5 seconds after my discovery a male *Cooper's Hawk* flew in like lightning from behind me and snagged the owl from its perch. The hawk took the owl down near the ground in a private yard, where it was not in plain view. This was within 75 feet of an active hawk nest. The owl was apparently unusual in the cottonwoods of Massey Draw during summer; it was the first I had found near my home outside of late winter. Blue Jays began intense scolding and mobbing almost immediately after the attack and continued on for a long time.

[cobirds] Cooper's Hawk and fledgling and Ruddy Ducks in NW Denver tonight
Hi CoBirders I observed the Cooper's Hawk nest with an adult and a fledgling at Osceola St. and 64th Ave. in Denver tonight at about 7 pm.The young bird was moving up and down in the nest. Tom and Laurie Simmons were there. they have been watching Cooper's nesting near this location for about six years, I've watched for four years or so. We also went to Berkeley Lake Park where two male Ruddy Ducks were near the north shore. Ruddys are becoming my nemesis bird as they show up at Berkeley and Rocky Mtn. Lake parks, and at Jim Baker Res., but not at Lowell Ponds SWA. Bob Canter, Denver -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
