| SPRING BIRDS SLOW TO ARRIVE
The last weeks of winter were comparatively quiet with no cold weather
movements from the mainland. The returning Lesser Black-backed Gulls brought
with them a couple of Yellow-legged Gulls from the Mediterranean in late
February.
The long staying birds seem to be mostly on Tresco. The Greenland White-fronted
Goose was noted most days alongside the Great Pool. The American Pied-billed
Grebe was often rather exclusive but did visit the pool at Porth Hellick,
St. Mary’s on 17th-20th March. Also visiting St Mary’s was the Green-winged
Teal. Both of these would go missing for days at a time. The Buzzard was
still on Tresco by late March with the Hen Harrier visiting St. Martin’s
and Tresco on occasion. The Wilson’s Snipe was last seen on Lower Moors
on 6th March. This bird was still attracting visitors from the mainland
until the end of it stay. Both Long-eared and Short-eared Owls have been
seen occasionally. One of the latter was found along Porth Loo lane in
early March having damaged its wing, possibly hitting a wire.
Calm days meant it was much easier to find the Great Northern Divers
that were wintering here. At least twelve were noted in late February with
up to eight still around in late March. Two Black-throated Divers were
seen from St. Mary’s in early March. A female Eider has been noted from
Tresco, off the south end of Pentle Bay. More unusually are the records
of Grebes on the sea. One Slavonian was noted from St. Mary’s on 7th with
two on 17th and one being in the Eastern Isles on 20th. The latter was
accompanied by a Black-necked Grebe. During rougher weather large numbers
of Kittiwakes were feeding between the islands.
Apart from a scattering of Linnets there was no visible migration until
9th March when large numbers of Pied Wagtails and Meadow Pipits arrived
many staying a few days. With these a few more Black Redstart appeared.
The first Swallow of the year was over Lower Moors that day followed by
the first Wheatear on 11th and the first Sand Martin on 13th. As more Linnets
and Chaffinch reached the islands a Reed Bunting and a Brambling were found
on Tresco on 13th. Another Brambling was found at Carn Friars on 16th,
whilst looking for the latter a male Rustic Bunting was found in the same
finch flock at Carn Friars. This rare eastern bird has occasionally reached
Scilly during October but has never before been seen during the Spring.
More migrants reached Scilly on 21st including the first Sandwich Tern
of the year. The same day saw the islands second record of American Herring
Gull, feeding along the Garrison shore, and later that morning a Yellow
legged Gull off the back of the quay on St. Mary’s.
So Spring is slowly underway. All we need now is some light southerly
winds to bring us a few more migrants and our summer visitors. |
