Site description The island of Coll lies in the Inner Hebrides of western Scotland, north-west of Mull in Argyll and Bute. The IAB comprises an extensive area of maritime heath, blanket mire and open water in north-east Coll and the small islands of Gunna and Soy Gunna off the south-west coast. The site supports internationally important numbers of Greenland Branta leucopsis and Greenland Anser albifrons flavirostris, both of which roost within the site. The feeding areas of both goose species lie outside the IBA in other localities of Coll and Tiree.
