Acknowledgements. As usual the Royal Society for the Protection of Birds, the Suffolk Ornithologists' Group and the Dingle Bircl Club h a v e provided us with records from their Iogs. T h e Editors of the Norfolk Bird Report, The Cambridge Bircl Club Report and the Lowestoft Field Club Report have also passed on records and Information. We are most grateful to t h e m all.
Editorial. T h e present editor is retiring. He has done a fairly hefty stint for 17 years and feels that someone with new ideas and a new approach to editorial matters is now called for. H e will be handing over after the publication of this report to D e r e k Moore who is well known to Suffolk ornithologists and is B T O representative for the county.
Records for 1978 should therefore be sent to D. R. Moore, Crosslands, Cage Lane, Boxted Cross, Nr. Colchester, Essex b e f o r e the end of J A N U A R Y next without fail. Tel. Boxted 594.
N.B. Observers are reminded of the importance of sending in very fĂźll field descriptions of semi-rarities and of birds very much out of thcir normal season when reporting such occurrences. A n u m b e r of 1977 records had to be rejected by the
County Records Committee for lack of detailed descriptions. R e c o r d s of those species on the national Rarities Committee list should of course be sent to that body, with a copy to the County Editor. Review of the Year Not since 1965, the year of the 'Great Migratory Fall', has so much of ornithological interest occurred in Suffolk. Yet 1977 was a year of contrasts. The breeding season proved most disappointing as the cold wet weather which lasted from early April to mid-June resulted in a great lack of insect life just when it was most needed. In consequence most of our more important breeding species fared badly. At Minsmere the bittern population feil from thirteen pairs to seven, bearded tits did badly everywhere and both our colonies of avocets had a disastrous year with severe kestrel predation added to the lack of insect food for the young chicks. T w o of the four pairs of godwits were unsuccessful and at Minsmere most of the early broods of waders and terns were lost. Only the marsh harriers, less dependent on insect prey, prospered. It is not easy to judge the effect of the poor spring on other species, particularly the smaller passerines, but tits and especially long-tailed tits seem to have fared badly for the second year running. It was also the worst season within living m e m o r y for wild pheasants. To compensate for this rather gloomy picture it was a r e m a r k a b l e , indeed a vintage year for rare vagrants, perhaps the best we shall ever know. A new species was added to the Suffolk list and something of real interest was to be watched, somewhere in the county, practically throughout the year. T h e first rarity to come under notice was an American black brant which was found in February among the flock of brent geese on Trimley marshes. It was followed by a white Stork in the S a x m u n d h a m area in late March. An ortolan at Felixstowe in early May gave place at the end of the month to a pratincole, the second for the county. This bird remained at A l t o n W a t e r for some days, its aerial acrobatics giving pleasure to many observers who came from far and wide to watch it. Those who were too late were compensated by the sight of a red-necked grebe, superb in fĂźll breeding dress.
Vol. 17, Part 4
J u n e started well with a black Stork near Mildenhall, and d u r i n g the m o n t h there were a n u m b e r of white-winged black t e r n s at various coastal localities, an adult woodchat at M i n s m e r e a n d , at the end of the m o n t h , a Caspian tern and S u f f o l k ' s third r u d d y duck. T h r e e nearctic waders occiirred in S e p t e m b e r , a Baird's s a n d p i p e r and a pectoral sandpiper on the coast and a second p e c t o r a l inland at Bury St E d m u n d s . All were reported during the same week. O n 16th O c t o b e r a Iarge flock of c r a n e s — 2 6 seems to have b e e n the highest n u m b e r c o u n t e d — w a s seen by many people to c o m e in over the Stour Valley at Higham and head on south into Essex. This was certainly the largest party of cranes ever r e c o r d e d in Suffolk. Single cranes had been seen earlier at O u l t o n B r o a d , O r f o r d and H a v e r g a t e Island. T h e tally of r a r e vagrants gathered pace towards the end of the y e a r . O n 13th N o v e m b e r and following severe Atlantic gales, a new species for the c o u n t y — a Franklin's gull— a p p e a r e d at L o w e s t o f t . A week later an adult Sabine's gull was also seen t h e r e , while a probable L e a c h ' s petrel occurred off M i n s m e r e . T h e year e n d e d in style. O n Christmas D a y a sociable p l o v e r was discovered by the Stour near Sudbury. It lingered m o s t obligingly, s o m e t i m e s in Essex but generally on the S u f f o l k side of the river. T h e F r a n k l i n ' s gull was still at Lowestoft, the cynosure of all ornithological eyes, and on 21st D e c e m b e r two ring-necked d u c k s t u r n e d up at Alton W a t e r , to be joined later by a third. A m i d all this magnificence it seems hardly worth mentioning the Pallas's a n d icterine warblers, the Richard's pipits, the b e e - e a t e r , h o o p o e , goshawk and red-breasted flycatchers which visited us during the s u m m e r and a u t u m n and which n o r m a l l y would find h o n o u r a b l e mention in any county bird report. N . B . S o m e of the records of species m e n t i o n e d in this review are still being considered by the national Rarities C o m m i t t e e .
Migration ( B a s e d on i n f o r m a t i o n provided by A . G . Bishop, A . B o t w r i g h t , B. J. Brown, P. A . G r e g o r y , G . J. J o b s o n , C. J. L o w e , D . R . M o o r e , P. M u r p h y , M. C. Marsh, M. Packard et al) Little of interest occurred during the early m o n t h s of the
year which were generally mild and wet, broken only by a few Short spells of frost and snow. The numbers of many of our usual winter visitors such as great grey shrikes and bramblings were unusually low. Wintering divers and grebes were however more numerous than for some time, with a great northern diver and two black-necked grebes on the R. Orwell in January and a black-necked and a red-necked grebe at Benacre. Geese were present in force during the early months and tlocks of white-fronts 150 to 250 strong visited Havergate, Minsmere and Sudbourne. Lone bean geese occurred at Kessingland and Gedgrave in February and March, wnile the number of Bewick's swans rose considerably in the New Year with a large herd of 167 at Havergate and Gedgrave in February. The first few days of March were exceptionally warm and sunny and spring passage got under way much earlier than usual, with the first chiffchaff on 8th March and the first wheatears and stone curlews two days later. Swallows and house martins were also well ahead of their usual arrival times, and the first firecrests were Coming through at the end of the month. A white Stork, one of four or five reported in Britain at that time, occurred near Saxmundham. The first big passage of summer visitors was noted between Shotley and Minsmere during the second week of April with yellow wagtails and ring ousels prominent. This was followed by another big fall of wagtails about 23rd/24th April when two wood warblers also occurred inland, while next day 60 yellow wagtails, 20 pied and 2 white wagtails were counted on Covehithe beach. A grey-headed wagtail had been at Lowestoft the previous day. Sylvia warblers and terns were on the move at Shotley on the 27th and the first of the spring's ten pied fiycatchers was noted inland at Groton. A white-spotted bluethroat, a crane, two ospreys and a peregrine also turned up during that week. As usual spring passage reached its height during May with three Montagu's harriers on the 7th, an ortolan at Felixstowe on the lOth, and two more ospreys and another bluethroat at Minsmere on the 14th. The first red-backed shrikes appeared â€” very late â€” on the 17th and a pratincole and a red-necked grebe at Alton Water gave a fine finish to the month. Black terns were on passage throughout May and well into June and with them came a sprinkling of white-winged black terns and a lone bee-eater. The unexpected during the first
Vol. 17, Part 4
week of J u n e were a serin, a lesser grey shrike at Lakenheath and a great reed warbler at Wrentham. A l t h o u g h the first wheatears had begun to dribble through in early July, autumn passage did not start in earnest until mid-August with six common sandpipers at Euston on the l l t h , the first pied flycatchers on the coast two days later and a m a r k e d fall of wheatears, whinchats and redstarts at Felixstowe and Shotley. A hoopoe, a roller and a Caspian tern were also recorded on the coast and there was a good passage of wrynecks. With them came a scatter of icterine warblersâ€” some half dozen in all between Lowestoft and Languard Point. T h e first of five barred warblers reported during the autumn occurred with other sylvias at Minsmere on 20th August. Whinchats were prominent during the early part of September as were ring ouzels a little later and there was a massive passage of hirundines between the 19th a n d 2 5 t h . A n influx of snipe to Shotley on 3rd October included a n u m b e r of jack snipe, one of which was observed resting on s o m e o n e ' s lawn. During this period of north-easterly winds a big m o v e m e n t of wheatears, ring ouzels, redstarts and sylvias was recorded at Languard Point and included within two days of each other, a Pallas's warbler and a red-breasted flycatcher. A n u m b e r of coal tits also occurred at Languard, one being observed to come in from the sea on the 22nd. T o w a r d s the end of the month finches were coasting south and immigration by rooks, jackdaws and a lone rough-legged buzzard was recorded at Dunwich on 28th October. D u r i n g the first fortnight of November small numbers of goldcrests and many 'thrushes' were coming in from the east and two woodcocks were seen to make their landfall on 16th and 17th November. On 16th a considerable influx of starlings, blackbirds, fieldfares and meadow pipits took place at L o w e s t o f t and Benacre with parties of twenty to thirty streng Coming in from seawards all morning and 'the fields round Kessingland carpeted with blackbirds'. It was however a very poor autumn for immigrant goldcrests. Bewick's swans and brent geese increased considerably during D e c e m b e r and more than 200 snipe were present in the Shotley marshes. Right at the end of the year a mass influx of lapwings and golden plover evidently took place with unusually high numbers near the coast and, on Christmas Day, over much of West Suffolk. W.H.P.

Barnacle goose. — Small parties of up to four were present during Jan. in the Eastbridge area (FKC, GJJ), at Boyton (SJB) and Southwold (DV). One to three also Southwold and Shingle St in Dec., Homersfield in Feb. (DRM), Alton Water in March (MCM) and at Long Melford in Jan. (AAB). Some of these birds were probably "escapes' as was one at Wixoe on 14th March which carried a rust-coloured ring. So undoubtedly were four at Barham between Feb. and Aug. (PM) and 8 at Havergate in July. Brent goose. — Winter numbers at Shotley probably static at about 200 (MP). At Trimley on R. Orwell 500 + in J a n . / F e b . and 400 in Dec. A colour-ringed bird in this flock had been ringed near Maldon, Essex in Jan. 1974 and was subsequently noted at Shotley in March and in Holland that autumn and in Jan. 7 5 and Jan. '76 (MCM). Out of season birds were two at Shingle St in April and May and one there 14th/23rd June (JG, SOG). Three at Languard Pt. on 30th May included one of pale-breasted race (AJL). First immigrants were c.55 off Walberswick on 18th Sept. (SOG) A m o n g the Trimley flock of brents an individual which had all the characteristics of the Pacific brent goose or black brant (orientalis) was located on 7th Feb. (MCM) and was subsequently watched by many ornithologists. It is believed
that this bird had been present in the same area in 1976 and it a p p e a r e d again during the early months of 1978. This record is still being considered by the Rarities Cmtee. Egyptian goose.— Two prs. bred in the usual area near T h o r p e n e s s with up to 17 there during year. O n e pr. also at Oulton Brd. in May/June (CRN). Scattered records also from M i n s m e r e — 5 in Aug. (RSPB), Reydon in June (TN), Benacre in Feb. (BJB), S o u t h w o l d — 3 in Dec. (DV). Inland o n e at Barham Pits in Feb. (PM) and a pr. at Lackford Pits during year (BOT). Shelduck. — T h e usual high coastal population. Inland breeding, or attempted breeding, took place at Livermere, T u d d e n h a m , Sproughton and Stoke by Nayland. Casuals occurred at Redgrave, Framlingham, Gt. Glemham, Ixworth T h o r p e , Burstall and Sudbury. Ruddy shelduck. — O n e among shelducks at Cattawade on 26th J u n e ( M C M ) , seems likely to have been a feral bird.

Sixty-eight inland at Livermere and c.30 at Homersfield in Jan. A pr. at Boyton on 18th May and up to five at Minsmere in July. Gadwall. — G o o d numbers in both winters with 160 at M i n s m e r e in Sept. the highest count. Three in Ispwich docks with mallard is an interesting record. Teal. — N u m b e r s well up with between 500 and 600 at Minsmere in Nov./Dec. and at least 25 breeding pairs. Pintail. — H i g h e s t winter counts were: 210 R. Stour in Feb., 100 plus R. Orwell in Jan. and 140 in Dec. and 100 Orfordness in Dec. Twelve inland at Lackford G P in Nov. Garganey. — T h e only breeding record was of one pr. "probable' at Minsmere (RSPB). Otherwise scattered records from H a v e r g a t e , May/June; Holbrook (a pr.) on 7th April, O r f o r d 8th May, Walberswick 27th May and end July, and Alton W a t e r , 25th Sept. and 2nd Oct.

Elsewhere 4 prs. at three sites reared 4, 4, 3, and 2. This total of 23 fledged young from 9 females is the best ever. There were the usual autumn, winter and passage records. Hen harrier. — More records than for some years were received. A very late ad m. at Cavenham on 12th June was clearly identified ( R N H , KCR). Females also at Minsmere, 26th Apl. ( R S P B ) and Shingle St, 8th May (GStJH). First noted in autumn on 24th Sept. Two at least on Breck, J a n . / A p l . (many obs.). Four/five inc. one m. Jan./Feb.

There were five or six sumttier records from elsewhere but no definite evidence of nesting. Some twenty-six scattered records of passage and wintering birds on both sides of the county, included four from the Walberswick area in January. Buzzard. — Singles recorded from coastal areas in following m o n t h s : Jan. (4), Feb. (4), March (3), Apl. (1), May (1), Oct (2), Nov. (1). Some duplication of records seems likely. One of the Feb. birds was seen to fly out to sea from Aldeburgh (SOG). Rough-Iegged buzzard. — A poor year with singles only at Walberswick, 12th March and in Butley/Rendlesham area mid-Feb./mid-March, and at Minsmere, 22nd Nov. and 12th/14th Dec.

( D R M ) , Minsmere/Blythburgh 8th/14th May (CSW, D R M ) , Ipswich, 24th May ( A M G ) and Alton Water, lst/2nd June (many obs.). T h e r e were no autumn records. Kestrel.—Breeding nos. in centre and south west of county probably remain low but 4 prs. were located in one parish on edge of Breck (PJE). Nine were counted hovering over shore pools at Walberswick on 31st July ( J R R ) . Fairly common in coastal belt with perhaps one pr. in most parishes. Also c o m m o n in Waveney Valley ( D R M ) . Encouraging numbers were noted during autumn/winter and early spring (1978) and the species appears to be on the up-grade. A nice little episode was witnessed at Haskerton involving a kestrel and a stoat. The stoat, carrying a mouse, was r o b b e d of its prey by the kestrel. The stoat, considerably nonplussed, spent 5 minutes searching the area for its lost d i n n e r while the kestrel quietly ate it in a tree overhead (J. Goldsmith per S O G ) . Merlin. — S c a t t e r e d coastal records Jan./March, including t h r e e birds at Walberswick, and from mid-September at M i n s m e r e , Walberswick, Shingle St. and Sudbourne and inland at L a k e n h e a t h in Dec.
299 Hobby. — High numbers again reported, including several mid-summer records which suggest possible breeding. The first at Wortham, 26th Apl. (SOG), Minsmere 5th May, 17th/20th June and on four dates in July. Alton Water, 28th May/ 2nd June (AMG, CAEK et al), Walberswick, 23rd May, 5th June (FKC, DBC), Oulton Brd. 25th/29th June (GWM, DRM) and in one other area which shall be nameless, for about six weeks in May and June. Autumn passage birds at Ipswich/Sproughton on 3rd/4th Sept. (PM, SOG), Walberswick, lOth Sept. (DAP) and Minsmere, 14th Sept. (RSPB). One at Walberswick on 28th May was seen to take a large bat, probably a noctule (DBC). BIRD REPORT
Peregrine. — Immatures at Shingle St., 15th Feb. (SA) and Beccles Common, 25th Apl. (DRM). Red-legged partridge. — Breeding success of both species Grey partridge.— was quite good but except locally near coast and in NW Suffolk the red-leg now far outnumbers the grey partridge almost everywhere. Quail. — An ad female found dead at Walberswick, 15th July (SOG). Pheasant. — It was an exceedingly bad season for the pheasant, an earlier breeder than the partridge. Golden pheasant. — Widespread and possibly increasing on the Breck and its vicinity. Water Rail. — Widespread reports of wintering birds but few breeding records were received though bird is numerous in coastal reedbeds in summer. Spotted Crake. — Only noted at Minsmere on 3Ist Aug. and 6th/19th Sept. (RSPB). Corncrake. — Gt. Glemham, 15th Sept. (C) and one dead at Shotley during harvest (MP). Moorhen. — In early July one was seen to be eating newly-laid carp eggs in a pond at Gt. Glemham (C). Coot. — Widespread in all suitable habitats and in high

On 16th Oct. a flock of 26 a p p e a r e d over the Stour valley at Higham St. Mary ( D D - J , H J W ) and headed away into Essex. Avocet. — This species had a disastrous season. The cold w e a t h e r and lack of insect food combined with kestrel predation wiped out practically all young of both first and second broods. A t Havergate 85 prs. reared one young and at Minsmere 52 prs. succeeded with only 3 young. A t one isolated site a lone pr. reared four young and at a f o u r t h site two prs. were unsuccessful. At Havergate 26 adults wintered locally. Stone-curlew. — T h r e e prs. are believed to have bred, success u n k n o w n , in coastal belt. Breck nos. uncertain with few definite records.

E x a m p l e s of tundrae at Lowestoft, 5th May and 7th Oct. (BJB). Kentish plover. — A scatter of mainly single birds between 8th May and 12th Sept. — some 11 individuals in all, including two at H a v e r g a t e in July. Golden plover. — From the low numbers recorded in late 1976, wintering population built up in New Year and included c.400 at H a w k e d o n ( R W G ) and 500 at Walsham le Willows ( S O G ) in March. These numbers were greatly exceeded during late
Nov. and Dec. when counts of 1,500-2,000 in Mutford/ Carlton Colville area (BJB), and c.650-700 at Falkenham/ Felixstowe ( A J L , S O G ) were made. Grey plover. — The winter population both early and late was below average with a max. of 250 at Trimley in Feb. ( A R J P ) and 150 at Erwarton in Sept. (J. H. Jones per SOG). Oversummering probable at Walton Ferry and Holbrook (SOG). Sociable plover. — O n e with lapwings in the Stour valley between G t . Cornard and Bures, 25th Dec —15th Jan. 1978 ( M R L , G C W et al).

May, Minsmere, 4th June, and Ipswich docks, 28th Oct. An imm at Benacre on 19th Aug. caused some controversy among experts before it was finally identified. It was feeding with dunlins, probing in the mud. Not the usual habitat for this species. Dunlin. — The usual widespread coastal reports. Small nos. also inland at Sproughton, Gt. Blakenham and Lackford. Ruff. — Recorded at Minsmere in every month with peak nos. in March and April and August, Sept. and Oct. and highest daily nos.—55 — in March and Aug. (RSPB).

Long-billed dowitcher. — Two arrived at Havergate during last week in Oct. and remained there into the New Year—an exceptionally long stay. Woodcock. — Very few breeding records came in but the species is certainly under-recorded as most breeding probably takes place in game preserves but the high numbers present throughout the county in Nov./Dec. indicate a massive immigration. Black-tailed godwit. — One pr. probably bred successfully on coast with two more prs. attempting to do so (FKC, GJJ). One other pr. on coast are known to have hatched young (SOG). Good passage and wintering numbers with 540 on R. Stour in Dec. (EFK, SOG). Bar-tailed godwit. —Present at Havergate during most of the year. A light coastal passage to 8th May. Whimbrel. — Spring passage from 14th Apl. and return migration from 15th July to 15h Oct. A flock of c.70 at Benacre on 20th Aug. (MCM, PM) is unusual.

Turnstone. — O n e in Ipswich docks in Jan. was feeding on spilt grain ( S O G ) and two at Gisleham were feeding in partly cleared beet field in Nov. (BJB). About 12 over-summered at Walton Ferry with odd birds at Minsmere and on R. Orwell in June. Red-necked phalarope. — Havelgate, March (RSPB), Benacre 20th Aug. ( D R M ) and Minsmere, 19th and 23rd Aug. and 3rd Sept. (RSPB).

Black-headed gull. — B r e e d i n g colonies at Minsmere and Havergate were respectively 900 and 800 prs. streng (RSPB). There were also two small colonies in the N . W . , one being newly established. Three birds found dead on coast had all been ringed as nestlings in Poland in 1976 (SOG). The habit of this species of feeding in evening on Aying cockchafers and ants was very marked in Ipswich parks during the summer.
