Which would probably rule out Kalinago wren.

Depends on whether it is current or historical distribution you think about. As far as I remember, Dominica is the only place with a Kalinago territory today. The Kalinago in St. Vincent were forcibly moved to Roatan from where they moved to Belize, it seems.

A dark reddish brown color could be Umber?

From descriptions, martinicensis and gadeloupensis don't really seem to have shared the colour of rufescens...

(A specimen of martinicensis: Multimedia item - RMNH.AVES.110001_0 | Naturalis Bioportal )

(Ridgway described Troglodytes guadeloupensis [Guadeloupe Wren] as duller than T. rufescens [Dominican Wren], and T. martinicensis [Martinique Wren] as still much duller than T. guadeloupensis.)

Wow...good timing. After discussion of how this forum is dead, NACC just posted there next batch of proposals, with some pretty interesting changes

Surprised to see the Herring Gull split there!

Surprised to see the Herring Gull split there!

Clements I believe is the hold out on that split, so they sort of have to address what with the checklist reconciliation process going on.

Southern and Northern House Wren split should get a ton of birders an armchair tick...both are widespread and pretty easy to see.

Including me!

Does anyone know what the range of the new Brown Booby taxa would be? Do the two overlap anywhere?

What's the Southerly limit of Northern?

I've never been North of Florida so I guess all I've seen is Southern.

The most likely version of the proposal to pass would have Northern range through most of Mexico, with the Yucatan and further south Southern.

Any House Wren you saw in Florida would be Northern, if that is what you are wondering.

luecogaster - Atlantic and Caribbean islands: Fernando de Noronha (ne of ne Brazil), coastal

brewsteri - islands off w Mexico: from c Baja California and Gulf of California (nw Mexico) to

etesiaca - Pacific coasts of Central America and Colombia: Gulf of Fonseca is. (Honduras) to

plotus - Red Sea through Indian Ocean to w, c Pacific Ocean: Red Sea, islands off Somalia

If you saw any in Florida they would be Northern. It's a Nearctic-Neotropical split.

That's the nesting ranges, but of course boobies wander far at sea.

So true, and this could have ramifications for the British list, the well twitched birds last year will now be 'sp', upsetting a lot of people!

Thanks, where do they become Southern?

 

[pbjosh]

Surprised to see the Herring Gull split there!

They are not even each others sister species or particularly close in the large white headed gulls. Unless you massively reduce the number of recognized species this split is mandatory and the evidence seems basically overwhelming.

Way more involved than just Southern and Northern!
