Dunlin - 1980s winter atlas

The BTO winter atlas showed that Dunlins were present in several coastal and estuarine 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over 900 birds.

The distribution is consistent with the Birds of the Estuary Enquiry (BoEE, now WeBS) at that time, with the majority of birds in the inland parts of the Cleddau Estuary complex.The Nevern and Teifi estuaries provided the main wintering grounds in the north of the county.

Dipper - 1980s winter atlas

The BTO winter atlas showed that Dipper were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over 4 birds.

The map indicates wintering outside the breeding range in SM 81.

Curlew - 1980s winter atlas

 

The BTO winter atlas showed that Curlews were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square, the darkest blue represents over 210 birds.

The distribution is consistent with the Birds of the Estuary Enquiry (BoEE, now WeBS) at that time, with the majority of birds in the Cleddau Estuary complex. The Nevern and Teifi estuaries provided most winter records in the north of the county.

Cormorant - 1980s winter atlas

The BTO winter atlas showed that Cormorants were present in most coastal and estuarine 10km squares and on some inland waters during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over 25 birds.

Coot - 1980s winter atlas

The BTO winter atlas showed that Coots were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over 119 birds, up to 300 being noted at Bosherston.

Common Scoter - 1980s winter atlas

The BTO winter atlas showed that Common Scoters were present in a few coastal and estuarine 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents more than 96 birds. Up to 420 were recorded in St Bride’s Bay (SM 81 & 82) and 650 off Amroth (SN 10) during this period.

Common Sandpiper - 1980s winter atlas

The BTO winter atlas showed that Common Sandpipers were present in six estuarine 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darkest colour represents 2 birds seen a day, the lighter blue represents one bird in a day. The UK is at the northern extremity of the winter range of this species.

Common Gull - 1980s winter atlas

The BTO winter atlas showed that Common Gulls were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents up to 400 birds in a day.

Found extensively using wet pasture and newly ploughed land but all roosts reported were around the estuaries.

Collared Dove - 1980s winter atlas

 

The BTO winter atlas showed that Collared Doves were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over 50 birds in a day, reflecting winter flocking.

Coal Tit - 1980s winter atlas

The BTO winter atlas showed that Coal Tit were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over 18 birds in a day. Probably numerically under recorded in dense conifer plantations during winter when they do not normally reveal themselves by singing.

Chough - 1980s winter atlas

The BTO winter atlas showed that Choughs were recorded in most coastal 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darkest blue on the map represents over 5-11 birds seen in a day, meaning immature birds were recorded as well as territory holding adults.

Chiff-chaff - 1980s winter atlas

The BTO winter atlas showed that Chiffchaffs were present in 41% of 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents 3 or more birds seen in a day.

However, it should be noted that the figures show a high correlation with the number of recording cards returned (therefore related to recording effort) for each 10km square.
