The habitats of the Isle of Mull are varied from mountains and moorlands to sea lochs and hill lochans, damp boggy marshes to sandy beaches. It supports a good range of resident and migrant birds, many passage birds call in to re-fuel en-route. Raptors include Golden Eagle and White-tailed Sea Eagle, Hen Harrier, Peregrine Falcon, Kestrel, Merlin, Sparrow Hawk and Buzzard. Barn Owl, Long-eared Owl and Tawny Owl are resident and Short-eared Owls visit to breed. Corvids include Ravens and Hooded Crow are plentiful. The Isle of Mull has a coastline of some 300 miles long and the tidal lochs are very attractive to many waders and birds of passage which stop to feed whilst en-route to their summer and winter feeding grounds. Whooper Swan, Bar-tailed Godwit, Greenshank, Redshank, Snipe and Whimbrel are just a few.

Large flocks of Teal and Wigeon over winter with Shelduck, Goldeneye and Merganser. All three Divers can be seen at different times of the year. Great Northern and Black-throated Diver in winter on the sea lochs and Red-throated Diver in fresh water lochs in spring and summer. Slavonian Grebe and occasional Red-necked Grebe can be seen on the sea lochs in the winter months

Corncrake have made a remarkable recovery due to sensitive and friendly farming  on Iona, and whilst not easy to see, they arrive on Iona in late April. Your best chance of seeing this elusive bird is in early May before the iris beds have  grown to make Corncrake almost invisible.

All the sea lochs on Mull hold otters and there are excellent opportunities to see Mulls’ otters along many of the coast roads.
There are many good and safe vantage points from which to watch sea birds, including, Guillemot and Black Guillemot, Shag, Cormorant and occasional Gannet and Great Skua. Boat trips are available to take you to the Treshnish Isles during the summer where you can get close to nesting birds, Puffin, Shag, Kittiwake, Guillemot and Razorbill.

Mink are a very serious problem on the islands of Argyll and ground nesting birds are suffering because of lack of controlling measures. These problems will have to be addressed if we are to protect them. A programme is in operation to protect Arctic and Common Tern colonies and this is proving to be very successful, and we need more such programmes operating.

Mull has lots of red deer and a small herd of fallow deer, hedgehogs, polecats, mink, rabbits, and Mountain Hare. There is a good population of otters which can now be seen regularly around the coast and sea lochs.
There are no badgers, foxes or squirrels on the island and we do not have any Magpies resident on Mull.


Lochdon is a  tidal sea loch and provides a valuable source of food for many waders, it  holds a good variety of birds at all times of the year, and is a regular stopping off and feeding area for spring and autumn passage migrants.
Good views of White tailed Sea Eagle can usually be had all year round from Lochdon & Grasspoint, also regularly seen are Golden Eagle, Buzzard, Kestrel, Sparrow Hawk, Tawny Owl, Short eared Owl and Hen Harrier and occasional Barn Owl, Merlin & Peregrine Falcon.  Red Kite have been seen in autumn on migration and the occasional passage Osprey calls into Lochdon, most often in Spring and Autumn.

There is a small colony of Marsh Fritillary at Lochdon and at a few other areas. Many other species of Butterfly such as Speckled Wood, Peacock, Scotch Argus and Common Blue can be seen on the wing at different times of the year.

Large numbers of Teal & Wigeon overwinter on Lochdon, joined by lesser numbers of Goldeneye, Red breasted Merganser, Shelduck and Mallard. Whooper Swan drop in and stay only to rest and refuel before flying off again. In winter occasional Goosander fish in the pool by the bridge to Grasspoint.
The mouth of the loch, from Grasspoint can be good for Great Northern Diver in winter & occasional Black throated Diver, Red throated Diver and Little Grebe. Redshank, Greenshank, Whimbrel, Turnstone, and Bar tailed Godwit on passage in spring and autumn, Occasional large flocks of Golden Plover & Lapwing in autumn plus Ringed Plover &  Curlew, There are Snipe & Woodcock at most times of the year.

Other resident birds including, Meadow Pipit. Rock Pipit, Stonechat, Song Thrush, Blackbird, Dunnock, Tree Creeper, Wren and Robin can be seen all year round. Great Spotted Woodpecker is common and is often seen feeding at bird tables and on nuts in local gardens. There is a Sandmartin colony at Gorsten (45 active nest holes in 2002).

Grasspoint will give good views of local sea birds, Guillemot, Black Guillemot, Fulma, GBB & LBB Gulls & occasional Gannets, & Kittewake.

Loch Scridain

Loch Beg is the small loch at the head of Loch Scridain and  it is tidal and providing good opportunities for feeding waders at all times of the year. There is good habitat for Hen Harrier, Short eared Owl and occasional Merlin.

Iona & Ross

The best place to see Corncrake is on Iona in May, the birds arrive regulary at the end of April each year. It is never an easy task seeing Corncrake, they are more often heard than seen but a trip to Iona can be rewarding for this bird.
There are many other species on the island and the journey from Craignure through Glen More gives opportunities for Short eared Owl, Hen Harrier, Raven and Golden Eagles.
The drive along the length of Loch Scridain can produce a wide assortment of birds.Stop at the Kinloch Hotel and check out Loch Beg with a scope, it’s one of the best wader sites, and in Autumn up to 100+ Golden Plover, Ruddy Turnstone, Greenshank & Redshank and others are regularly seen.
