Summer Twite movements

Our wintering twite are now arriving back at their summer homes over in the west.
Movements in 2010
Montrose birds leading the way. We’re seeing how many islands we get twite seen on now, so Rhum is a new one for the project this year, as is a belated sighting from last summer on Eigg.

Note the single Donside bird up north at Lochinver. Tony Mainwood has controlled over 30 Orkney birds, perhaps suggesting there is a bit of segregation in breeding aswell as wintering areas in Scottish twite. The further north they breed the further north they winter to a certain extent? Or are they just passing through to end up mixed all over the place?
Movements from all years
Birds wintering in NW Lancashire appear to breed further south on the Western Isles (though there is some overlap).

PS What call does the Finch Owl make? Twite a woo!!
