SACC now has a series of proposals (#448-454, Aug 2010) to follow changes resulting from the 51st Supplement:
SACC proposal #453 to recognise parulid genus Oreothlypis failed to pass 3 Jan 2011:

So NACC/Cornell & SACC agree to disagree on this one.

Revised SACC proposal #453x to recognise genus Leiothlypis (as per failed NACC proposal 2009-B-3):

Here is the summary of the new species (including vagrants now accepted) which are additions to the checklist


can anyone enlighten me why vagrants are "collected" on Attu island?
While i'd like to see it kept to a minimum I am a scientist myself and can understand the scientific and even conservation rationale behind collection of potential new taxa, but what do we find out from the collection of birds such as the solitary snipe and rufous-tailed robin mentioned?
as far as i know no-one is trawling round fair isle or the azores with a shotgun collecting migrants (at least not for scientific purposes....)
yours confused,

Might that be because there might be Azoreans with shotguns who would like to collect a collector?

Re; shotgun. I consider the ABA list as the USA version of uk400. The reason those two birds, snipe & robin, were shot is because two seen only records or poorly photographed were rejected by overly clenched sphincter-list committee members. SO birders said, OK here is a specimen.

I don't think the ABA is at all comparable to the UK400. For one, they strictly follow AOU on taxonomy, common names, etc. They also have an actual committee to vet sightings. UK400 is basically up to the whims of one person, with changes motivated as much by year lists as any change in science.

Also U of Alaska has been collecting on the islands for a long, long time. I doubt ABA had any role in their decision to collect those birds.
