Parsons, M.Heubeck, G. Pickerell and S.Schmitt on seabirds numbers and breeding sucess in the Isles of Scilly in 2004. FROM REPORT SUMMARY Some findings of particular note in 2004 are summarised below: The breeding season of seabirds in 2004 was the least productive on record, particularly so in the Northern Isles and in many colonies on the east coast of Britain. The available evidence suggests that severe food shortage was the primary causative factor. Breeding success of red-throated divers in Shetland was well below average, with total failure on Yell. In contrast, those on Orkney were very successful, due in part perhaps to low predation rates from great skuas (which failed early and abandoned territories). The number of breeding northern fulmars in most regions continued the decline that started in the mid-late 1990s. Breeding success was below the long-term mean in most regions, particularly so in south-east Scotland. Breeding success of Manx shearwaters was low on Rum, raising concerns that predation by brown rats was impacting upon this important colony, as they have to such devastating effect on adjacent Canna. On Lundy breeding was confirmed for the first time in 50 years (although few surveys have been undertaken in that period). The number of European shags that built nests in 2004 declined in some regions, likely due in some cases to food shortages. Breeding success was well below average, though colonies on the west coast did better than those on the east. Particularly low success was recorded in south-east Scotland and north-east England, due to bad weather and low availability of sandeels. The number of Arctic skua territories held in Shetland decreased by nearly 50% compared with 2003, and a near breeding failure occurred there, and those in Orkney fared only slightly better. Great skuas were extremely unproductive on Shetland (where interspecific depredation was noted) but less so on Orkney. Predation my mink continued to depress breeding success of mew-, herring-, and lesser blackbacked gulls and of common and Arctic terns in study sites in western Scotland, though great black-backed gulls appeared to be unaffected. The number of great black-backed gulls breeding on Orkney declined by 25% since 2003 and breeding success there appeared to be low. Poor weather and food shortages severely depressed breeding success of sandwich-, common-, Arctic- and little terns in the Northern Isles and along the east coast of Britain. The total breeding population of roseate terns in Britain and Ireland reached a 25 year high, but its breeding range contracted further, and none nested in Wales in 2004. Black-legged kittiwakes were severely affected by apparent low availability of sandeels. None were fledged from several study colonies in Orkney, and those in Shetland fared only marginally better. Many colonies on the east coast of Britain, and in Wales, were also unproductive. The population index of most regions was at its lowest level in the 19 years of the SMP. Numbers of common guillemots in study plots declined in most regions between 2003 and 2004 and attendance at many colonies was notably low, due to food shortages causing parent birds to spend longer periods foraging at sea. Mean productivity was extremely low; on Fair Isle no chicks fledged at all, which is unprecedented. Few sandeels were fed to chicks and predation on them from great skuas exacerbated the situation. |
