Way more involved than just Southern and Northern! Almost every Caribbean Island has it's own species now, one up for me with Grenada but wondering why tobagensis didn't get split?

2024-C-3l: Recognize multiple species within the House Wren Troglodytes aedon complex: Recognize T. albicans as a separate species sw Colombia and w Ecuador
I was so very confused by the proposal on this point: it doesn't mention tobagensis at all, and its text about albicans is:
(11) albicans—This taxon occurs both on Trinidad and in northern mainland South America
This doesn't match up at all with either eBird or IOC taxonomy. But birdsoftheworld.org has text (left over from HBW, I guess?) which says "
T. a. albicans Berlepsch and Taczanowski, 1883. Includes
T. a. clarus Berlepsch and Hartert, 1902;
T. a. paramaribensis Bangs and Penard, 1918; and
T. a. chapmani Stone, 1918". So I imagine the proposal's albicans is in that sense, but also they're talking about
just splitting the Trinidad population. At any rate, they recommend against a split, so the question is moot:
"(11) Split Troglodytes albicans
of Trinidad.—We recommend a NO vote on splitting the
albicans populations of Trinidad from those on the South American mainland."
(emphasis mine)
Anyway, the important thing is I might no longer have to vociferously whinge about Cozumel and St. Lucia Wrens not being split (these are laughably unlike House Wrens!)
