"Great find this morning in the harbour, in about 100 yards of each other, Guillemots, Razorbills and a beautiful Northern Diver, the light and sun was so strong it was difficult to get good pictures but I had a go ... Here is a slightly out of focus Razorbill, kept diving and then went altogether before I could get a good picture and then a couple of nice Northern Divers

I tried to get a picture of the Diver with a fish in his mouth, just when I lined one up beautifully look what happened! Not sure who was most surprised about losing his brunch the Diver or me!"

In April and May numbers of Great Northern Diver gather together ready to begin their return trip to Greenland and Iceland. Many will be in breeding plumage. The usual gathering sites are Broadbay (near Stornoway) and the Sounds of Harris, Taransay and Barra. Single birds may be seen offshore during most months.

Small numbers of returning failed breeders and immatures may be seen offshore here as early as August, but the birds usually leave their Northern breeding sites in September and October arriving here in October and November.


On the chart below the darker the shade of blue the more abundant the bird is during a month or the more likely you are to see it.
