Moltoni's Subalpine Warbler Split

Today I heard of the recent split of Moltoni's Warbler from the Subalpine Warbler.

This is a bird recorded three times in Shetland, the most recent on Fair Isle (which I got) and an addition to the Shetland List which now stands at 441.

Also an addition to my list which now stands at 227.

Here's a Link to the news on the Split.
