Cooper's in the news

Trouble with my account...Anyhoo I recall reading upon a news article that talked about the cooper's hawk killing pigeons at a home depot. Could anyone dig up this story and provide a link?--68.161.121.166 00:26, 5 April 2006 (UTC)[reply]

Comparison with Sharp-shinned Hawk

I added this image as a comparison on the Cooper's and Sharp-shinned pages. The originals show the difference in shape of the tail well, but were not done to scale, so I re-sized the Sharp-shinned to be somewhat smaller than the Cooper's. They are real variable, I understand, with the female Sharp-shinned very close in size to a male Cooper's. I think this adds something to the pages, but I don't intend this to be any sort of exact scientific statement.

I noticed on the images you were referring to, that the Sharp-shinned hawk has a different posture. Is that typical? Is that something I can use to determine the Cooper's from the Sharp shinned? We've been watching one for months in our backyard. He finally killed a dove right in front of me but we can't be sure which one it is. —Preceding unsigned comment added by Sandiholmes (talk • contribs) 19:26, 8 February 2007

Improving the article

Luckily, cheating improving this article should be straightforward as birds of prey have been popular among wikipedia editors - Peregrine Falcon, Bald Eagle, American Black Vulture are featured articles, and Osprey and Red-tailed Hawk are Good Articles (a good way station/check point along the way). I reformatted the headings like the other articles. Cheers, Casliber (talk · contribs) 00:09, 24 October 2008 (UTC)[reply]

Thanks for the formatting--PeaceMaker00 (talk) 17:43, 12 November 2008 (UTC)[reply]

Just uploaded a new picture for the taxonomy box on the right hand side. Didn't feel like the last one was very descriptive of the bird, just showed the back, which is pretty boring and doesn't really help identify the bird easily. New picture is the bird in profile and shows the distinctive markings and shape of the head. New picture is higher resolution, and slightly less grainy, though I wish I'd dropped the ISO level down a notch, but it was shot in a bit of a hurry, how often does a Cooper's Hawk land in your yard? (Yes, I have an EOS 50D with a 400mm lens laying next to my desk for a reason ;). I have another picture with it's wings partially open, but I'm not too great at finding where to fit things like that in, or deciding if they'd be a good addition.

Found Coopers Hawk now named Traffic as that is where we found him.

We found a disoriented Coopers Hawk in traffic, in the middle of a 4 lane highway with traffic traveling at 50 mph. After rescueing him we took him to Waldens Puddle near Nashville. If you are considering donating to a worthy wildlife center, this is it. These people really care. Any way, be on the lookout for sick or injuried birds. You never know what you may find and they are truely amazing.166.248.139.73 (talk) 01:54, 5 February 2012 (UTC)[reply]

Cooper's Hawk eggs

We have CH visit us regularly. They are beautiful. I was reading your article about them, and it stated that CH eggs are cobalt blue. I am a professional artist. Cobalt blue is the color of lapis lazuli. A rich, dark, royal blue. The photos of CH eggs are better described as pale, Robin's egg blue, teal blue, pale Tiffany blue, Cerulean blue. FYI. Love Wiki, use you every day!

distribution map key?

Is there a key for the distribution map? I see various colors on the map, but not sure what they mean. Pdanese (talk) 21:26, 13 August 2022 (UTC)[reply]

When you click on the map, the key will show up. Aythya affinis (talk) 14:52, 15 August 2022 (UTC)[reply]

Updating taxonomy

The taxonomy section is currently confusing/self-contradictory due to an apparent recent change in genus for the Cooper's hawk. I am unsure what the most accepted classification would be, but the section needs a rewrite to meet current scientific standards. Anonrfjwhuikdzz (talk) 15:41, 23 May 2025 (UTC)[reply]

@Aa77zz: Another one for you to look at. Cheers mate! - UtherSRG (talk) 22:33, 23 May 2025 (UTC)[reply]

@UtherSRG and Anonrfjwhuikdzz:. I'll take a look - it may take me a couple of days. From the comments in the history I can see that I was aware of the problem when I change the genus from Accipiter to Astur in August 2024. I was put off by the enormous size of the article - and hoped another editor would fix it. - -Aa77zz (talk) 05:57, 24 May 2025 (UTC)[reply]

Referencing problems

As well as this article being very much too long there are problems with the citations. I've only checked a few references - to check them all would be a big effort. It appears that some of the citations are to the wrong reference. (Reference numbers for this version)

40. Reynolds, Richard T. (1972). "Sexual dimorphism in Accipiter hawks: A new hypothesis". The Condor. 74 (2): 191–197. doi:10.2307/1366283. does not support:

• "In general, sharp-shinned hawks tend to use younger and denser stands of trees than do Cooper's. Meanwhile, goshawks tend to favor old-growth forest area with taller and older trees and generally lower tree densities."
• "Douglas firs (Pseudotsuga menziesii) were preferred in northwest Oregon (94% of 18 nests) and also in northeast Oregon as well as in British Columbia (34% of 64 nests), often where mistletoe parasitizes the tree (64% of 31 in the overall state of Oregon were on mistletoe)."
• "Ponderosa pine (Pinus ponderosa) were preferred in eastern Oregon (53% of 15 nests) as well as in New Mexico."
• "South-facing nests are thought to be avoided, possibly due to solar irradiance reducing soil moisture, tree density and shading or possibly due to the more deciduous local nature of north-facing nest sites."
• "81% of New York nests produced fledged young and 75% did so in Pennsylvania."

• "Males were found to do 70% of the nest building in Wisconsin but the female does not consistently take a secondary role. Mostly, the male gathers nesting materials within 100 to 200 m (330 to 660 ft) of the nest."
• "Near Stevens Point in Wisconsin, males prefer to hunt in quiet woods while females preferred to stay within 100 m (330 ft) of the nest making males a more common sight."

• "In Tucson, nest building was recorded during winter, exceptionally." (Cooper's owl not mentioned)
