show however, that spring birds are more likely to linger, and search for food, hence the large catches. Interchange between the island of Guernsey and Landguard has now been proved on four occasions. Two birds bearing Guernsey rings were trapped at Landguard during a three day period in April and both birds had been ringed within the space of five days in February. Another ringed at Landguard in March, 1986 was located on Guernsey, Jan. 4th and 25th. Time will tell whether this is a regular wintering haunt or whether the species was forced to retreat south-westwards at the onset of hard weather (see also Ringing Report). Coastal autumn passage was only reported at Landguard where the maximum day total was 500, Oct. 12th. Flocks elsewhere in the mid-autumn period were 130, Eastbridge, Oct. 3rd and 300 Trimley Lake, Nov. 8th.
GOLDFINCH Carduelis carduelis Apart from 30, Stradishall, Feb. 22nd, very few were reported during the first winter period. Most breeding birds arrived during late April and May but insufficient information was received to comment on population levels. Autumn migrants were recorded at Landguard between Sept. 18th and Nov. 29th; as has come to be expected at this site, movements peaked in October with 500 passing through, 10th and 200 on each of 6th, 12th, 19th and 22nd. Early-autumn "charms" in September included 75, Minsmere, 18th; 100 on saltings, Hemley, 23rd and 100, Cavenham Heath, 24th. Wintering groups in December were of 30, Levington, 3rd and 40, Bourne Park, Ipswich. 31st.
SISKIN Carduelis spinus Not as abundant during January to April as in the equivalent period during 1986. However, flocks of 50-75 were noted at West Stow, Great Glemham, Southwold, Minsmere. Redgrave, Tuddenham (west) and Cavenham; a mixed flock with Redpolls totalled 100 in Christchurch Park, Ipswich, Feb. 2nd. Birds were attracted to peanuts in gardens at Southwold, Ipswich, Haverhill, Martlesham and Gunton. A pair bred successfully in the coastal region, while a report from the Thetford area was of " m a n y " juveniles in the summer months. Another observer remarked that the breeding population in the Breckland Forestry Commission woodland had decreased during the last two years. Unusual summer reports came from Landguard, June 17th (six), July 3rd and July l 4ttl (juvenile). Two early autumn arrivals were at Minsmere, Aug. 30th. Only 17 were r e c o r d e d on autumn passage at Landguard during Sept. 11th to Nov. 27th (140 in 1986); this was reflected elsewhere during the second winter period with reports from only 13 sites. The largest gatherings were of up to 60 at Eastbridge, Nov. 18th and Melton, Dec. 26th-
LINNET Carduelis cannabina The only reported movement in response to the onset of severe weather in January of 105 flying south at Landguard during Jan. 12th to 14th. Flocks encountered in the first winter period included 120, Lackford, Feb. 26th; 10"Felixstowe Ferry during January and 100 roosting at Landguard in early March. Coastal spring passage occurred between late March and late April. The largest floc was of 200 Walberswick Mar. 29th while at Landguard peak movements took place in April on 10th (95) and 21st (96). 94
