During spring 2004 an exceptional movement of Temminck's Stints took place, with a minimum of 226 birds reported on Bird News Extra. The majority of records were along the east coast, primarily between Kent and Northumberland, though much smaller numbers penetrated into the Midlands. As is usual, records further west were scarce and relatively few reached further north to Scotland.

Temminck's Stints breed mainly in the tundra zone from Scandinavia eastwards to eastern Siberia. A very small population of breeding birds occurs in the Scottish Highlands, but number just two-three pairs in most years. The bulk of the European breeding population occurs in Russia, with an estimated 1-10 million pairs. The main wintering areas are from Mediterranean basin and northern Afrotropics across the Middle East and east across southern Asia to Japan.
In Britain, apart from the small breeding population, it is predominantly a scarce passage migrant, with numbers varying from year-to-year. Annual fluctuations are no doubt determined by a number of factors, but key during spring migration periods during an overland movement through Europe between mid-April and mid May will be weather patterns across the continent. Britain lies at the western edge of the migration route, thus there is variability in the numbers of birds reaching our shores. The prime period for this scarce stint is condensed into the period mid- to late May, with stragglers met with well into June and there is, as with most waders, no obvious gap between northbound birds and the first returning birds of the autumn. Autumn numbers are fewer in number, with failed breeders presumably accounting for early 'autumn' sightings. There is a clear east-coast bias to the records, with Temminck's Stints much scarcer further west and into Ireland.
During the period 1968-2001, there were around 3,106 recorded in Britain. The best year ever for the species was 1987 when the annual total was 176 birds, most of which were associated with a dramatic spring movement. The second-best year ever was 2001, when 134 were noted. Annual means for Britain in 10-year periods are: 71 between 1968 and 1979, 105 between 1980 and 1989, 95 between 1990 and 1999 and 131 between 2000 and 2001.

The forerunner of the spring 2004 movement was a single bird at Saltholme Pools (Cleveland) from 22nd-24th April which at the time was perhaps of little interest in other than the fact that it was relatively early (a delve into county avifaunas reveals just one April record in Yorkshire, four in Norfolk and one in Suffolk; compare this with the earliest for Shetland which is 17th May). This was followed by another April record, with one at Ynys-Hir (Ceredigion) on 26th April.
As would be expected, small numbers began arriving from 1st May onwards and nationally by 10th May there had been 16 birds recorded. The 11th May saw an arrival of seven birds, including three together at North Cave Wetlands (E. Yorks), which had increased to four birds by the following day. These were very much the forerunners of the main arrival, with daily totals of new birds in double-figures on 13th and 14th May. The peak arrival took place on 15th May when 30 new birds arrived, with 24 the following day. Thereafter, numbers declined steadily, though between 9 and 18 new arrivals were noted daily between 17th and 23rd May, with the end of the main passage occurring on 26th May. After this date single figures were recorded on several dates into June. By the end of June around 226 birds had been involved with the spring movement, a total eclipsing the record annual total of birds in 1987. The spring 2004 estimate represents a minimum value, as it has been assumed here that there was minimal turnover at sites, though in reality this was probably not the case. In addition, 'new' birds were assumed at a given location only where there had been a significant gap between sightings.

As would be expected, the majority of sightings were along eastern England between Kent and Northumberland. The largest number of birds were reported in Norfolk, where perhaps as many as 34 birds revealed their presence, followed by Suffolk with 19 birds. Other counties to accumulate double-figure counts included Cambridgeshire, Cleveland, E. Yorks, N. Yorks, Kent, Lincolnshire and Northumberland. There were numerous reports of multiple occurrences, but some notable flocks were detected. These included: 5 at Buckenham Marshes (Norfolk) on 16th May, 6 at Filey (N. Yorks) on 16th May, 6 at Wicken Fen (Cambs) from 16th-17th May, 7 at Hickling Broad (Norfolk) on 17th May, 6 at East Chevington (Northumberland) on 20th May, and 7 at Druridge Pools (Northumberland) on 21st May.

Given the elusive nature and small size of this delightful stint, one can only wonder at how many birds sneaked through our larger wetland areas?
