The numbers of Tüfted Duck and Pochard at Alton Water continue to decrease, possibly due to disturbance by those pursuing sporting activities. Aythya Hybrid: One showing characteristics of both T\ifted Duck and Pochard at Livermere 3rd and 24th April, and another - species involved not specified - Thorington Street Reservoir, 16th Oct. Scaup: A female Benacre Broad 1st—16th Jan. 3, including a male in Ipswich Docks, were noted on the River Orwell 16th Jan. At Minsmere a pair were present 4th-16th Feb. Exceptional numbers at Alton Water with a total of 16 birds being recorded in Jan; 8 throughout Feb. and until 8th April, and 5 remained until 26th April. Early return birds were seen at Benacre; 2 males 20th July and 2 females 12th Aug. In Ipswich Docks 8 immatures were recorded lst-2nd Sep. and at Landguard a female was noted flying south on 11th Sep. At Alton Water at least 2 were present from 27th Aug. increasing to 6 by 26th Nov. The latter and a female at Benacre remained until the end of the year. Eider: The largest feeding flock during the first winter period was 37 off Dunwich cliffs, 8th Feb. Up to 18 were recorded from the Lowestoft/Benacre area throughout Jan. and until 29th April. 1 - 5 were reported from the Orwell Jan.-Feb. Other records of up to 3 birds were received from Aldeburgh, Minsmere and Walberswick. A flock of 18 on the sea off Landguard and singles at Havergate and Lowestoft all 8th May were probably part of a spring movement. However, an over-summering flock of up to 8 birds were noted off Lowestoft from 27th May, increasing to 13 by 13th July and 17 by 11th Sep. (Records of 3 at Walberswick 24th June and a single off Minsmere 21st June were probably part of this flock.) Coastal movements were noted from 20th Sep. to 1st Dec. with an exceptional passage in the period of 12th-14th Nov. Highest totals received were 120 south off Benacre 12th (during a 3-hour spell); 50 north off Gunton 13th and 15 and 20 north off Landguard 13th and 14th respectively. Otherwise second 14
