    Petition to AOS Leadership on the Recent Decision to Change all Eponymous Bird Names

    Well - yes - number of publications certainly correlates with age - and we don't have the data regarding membership of the AOS - although I do know that a substantial number of the AOS has not signed, yet does not support the full removal (the fear of going public with ones disagreement of this...

    Petition to AOS Leadership on the Recent Decision to Change all Eponymous Bird Names

    My point about publications is that the AOS is a "Science" organization for scientists - so the criticism of "birders" out there is one thing, but it is also coming from the very people who are members of the organization, and are contributing to science. I would think that the AOS would want to...

    Petition to AOS Leadership on the Recent Decision to Change all Eponymous Bird Names

    → I realize eponyms are important for many. For me, they aren’t (and I know that, even if I was an ornithologist ‘worth’ an eponym, I wouldn’t want it), but I won’t underestimate the value some (many) people give to them. I know Gary went on expeditions that discovered new species, and some of...

    Petition to AOS Leadership on the Recent Decision to Change all Eponymous Bird Names

    5) Most people are in favor of this decision. Well, that is an opinion not really supported by fact. Thousands of birders and ornithologists have signed a counter petition, so I would say the jury is out on that one. Furthermore, Of those who signed our counter petition, they have produced...

    Petition to AOS Leadership on the Recent Decision to Change all Eponymous Bird Names

    I would like to say a couple of things about the degree to which the IOC (or AOS) change English names. I suspect, although I haven't checked each one, that the list of "recent" changes by the IOC mentioned above "mostly" are the result of scientific/taxonomic changes - that is certainly the...

    Poll - Do you agree or disagree with the AOS's recent decision to abandon the use of eponymous bird names?

    It has been interesting to read the perspectives on this forum. Given that I was named above, I thought I would mention a few things from my perspective. It has been pointed out that very few North American birds are named after people (about 5%), and MOST of those are respected ornithologists...

    Not Another Hawk!

    Great discussion about the Dyess Creek bird - what a cool looking bird and some very enlightening insights into Red-tailed Hawk/Harlan's Hawk identification issues. I was feeling woefully behind the times, so today I purchased Brian Wheeler's Western Raptor guide (about time!), and, as I...

    Not Another Hawk!

    Hi All, Just a few more comments regarding the Arizona bird. Determining different races within Red-tailed is certainly a big challange, particularly with potential intergrades floating around. I certainly see lots of Red-taileds in Arizona, particularly in winter when there is a big influx...

    Rufous-Crowned or -Winged sparrow? - Tucson, AZ

    Rufous-crowned or - Winged Sparrow? Yes, these are photos of a Rufous-winged Sparrow. The double malar stripe is an excellent field mark, as well as the rufous-colored spur behind the eye, and more finely streaked crown (with pale center crown stripe). I can attest to the fact that Saguaro...

    Not Another Hawk!

    Hi All, Sorry for not posting this more promptly. Although I was trying to quiz everyone, I was not trying to trick anyone. I figured most would see it as a Red-tail, and I was hoping that the discussion would gravitate towards which type of Red-tail it was. ;) I didn't ralize that the...

    Bird ID?

    Bird ID Not quite right for Masked Bobwhite. Photo of Masked Bobwhite can be seen at: http://k43.pbase.com/u48/photon180/upload/40666205.MaskedBobwhiteQuail02051j.jpg The mostly rufous plumage (including back), and white spot on chest suggest something different. But what, I don't know...

    Not Another Hawk!

    OK. Getting this one to species should not be too difficult. This was photographed in the Sulphur Springs Valley in s.e. AZ last week. It's a stunning individual, and one that reminded me greatly of a bird we called a juv. Harlan's type Red-Tail. Any takers? Gary

    unknown hawk

    Unknown Hawk Nice photos. I agree that the right hand image of the bird flying is also a Ferruginous Hawk. I believe the dark that appears on the throat is a trick of the light. I see what appear to be feathered tarsi, and the pattern of spotting on the underwing (without a strong patagial...

    Heron ID help please - Gt Blue or Cocoi?

    Great Blue vs. Cocoi Heron Hi Everyone, I am certainly no expert when it comes to immature Ardea herons, but the tarsus color (a mark I was unfamiliar with) certainly seems to hold when one looks at lots of photos of both (Google Images). I will say that in August I saw a couple of Cocoi...

    3 Bird ID's (Tucson, AZ)

    3 Bird ID's Number one looks like a Bell's Vireo to me - the habitat would be corect for this species as well. Number two looks like a Hutton's Vireo, althought it might be an empid - when was it taken. The common vireo in Madera Canyon is Hutton's. It it is an empid, it is certainly either a...
