    Galapagos passerines, taxonomic hesitations and conservation emergency !

    We suggested four species in the paper. The SACC accepted two species.

    Scolopaci

    We do not yet have the final pdf of the paper. Sorry about this. When we get one, I can put up a link to the final version of the paper.

    The jaegers do not hunt? Whaaaat. That is all they do in the Arctic, hunt!

    Species recognition between geographically isolated populations

    Andy. Actually "California" Common Ravens sound more like Chihuahuan Ravens, and they seem to rarely if ever give the complex clicks, pops, etc. that Holarctic Ravens give. As well, I think the extent of nasal bristles is different in the California birds. I think the real situation may be more...

    Willet

    Western Willets commonly over-summer along the East Coast. Usually they are in small flocks, show molt and rattier plumage than the breeding Eastern Willets in the same area. So yes, you can find the two in the same general areas in summer on the East Coast. Careful observers should be able to...

    Nevada and California 17th Aug to 5th Sept

    Hi there, I am glad you had a great birding trip to California! It is a nice place to bird, eat and drink. As a local here I should mention that there are various way out of range birds in the report that are likely mis-identifications, which is not unusual when one is traveling out of your...

    North American splits

    Of course other nuthatches like oaks, Oak Nuthatch may be an appropriate name for several out there, but they already have names. Names do not have to be exact, or the most appropriate, the more important question is that they not be inappropriate, or at least not too inappropriate. Someone in...

    North American splits

    Kirk, there has been no use of the names for these nuthatches for decades. So for the average user of bird names, there really is no tradition to them. At this point it is nearly a blank slate I would say.

    North American splits

    Nuthatches, on tours I jokingly would use Nuthatch, Oakhatch, and Pinehatch. Oak = Slender-billed, Pine = Rocky Mountain. It sort of works for habitat, although Pinehatches become fond of the oaks by the time they reach Arizona and into Mexico. Still, I would argue that the bird we have here in...

    English names for Clapper/King Rail split

    I don't think any of the forms should retain the old "Clapper Rail" name, but I don't see why the use of Clapper Rail could not remain in one of the other taxa names. In particular, there are oodles of reports that deal with Light-footed Clapper Rail, and California Clapper Rail as well as Yuma...

    King & Clapper Rails

    Hi there - just a note that Palo Alto Baylands have not been good for Black Rails for some years now. About 5 years ago they stopped being seen with regularity in the winter high tides unfortunately.

    Barred Owl - proposed split

    That should have been "informed opinion" rather than "informed information"... talk about ill informed.

    Barred Owl - proposed split

    Michael's point about the taxonomic committee being ill informed is a good one. I am on a taxonomic committee (SACC) and always consider myself ill informed about most things we are dealing with. I decide based on the patchwork of information given by other committee members, the public, and the...

    New Capito barbet

    In Chile we have a Scytalopus that is visually different from S. magellanicus, ecologically different yet sings nearly the same song. I am not sure if any specimen exist of the thing, but having a series and tissue would go a long way to figuring out what we have there - new taxon at some level...
