Bird Study

Breeding ecology of Turtle Doves Streptopelia turtur in Britain during the period 1941–2000: an analysis of BTO nest record cards: Capsule No trends over time were detected in any aspect of Turtle Dove breeding ecology and only slight regional variation, based on individual nesting attempts recorded.

Breeding performance and timing of breeding of inland and coastal breeding Cormorants Phalacrocorax carbo in England and Wales: Capsule Breeding performance was higher at inland colonies than on the coast due to higher nestling survival during late development.

Decline of the Orkney Hen Harrier Circus cyaneus population: do changes to demographic parameters and mating system fit a declining food hypothesis?: Capsule A decline in polygyny and lower secondary female breeding success have reduced male productivity and most likely led to the population decline.

Within-winter movements and site fidelity of Icelandic Greylag Geese Anser anser: Capsule Levels of mobility and turnover changed at different stages of the non-breeding season.

Evaluating the Breeding Bird Survey for producing national population size and density estimates: Capsule The BBS has potential for producing better estimates of habitat-specific densities and population sizes for many UK bird populations than those available previously.

Changes in the numbers of breeding waders on lowland wet grasslands in England and Wales between 1982 and 2002: Capsule Lapwing, Snipe, Curlew and Redshank decreased significantly between 1982 and 2002, while over the same period Oystercatcher increased.

Effect of intraspecific interactions on seasonal decline in productivity of Common Terns Sterna hirundo: Capsule Kleptoparasitic activities of older chicks from earlier nests did not contribute to late reproductive declines.

Comparative population dynamics of Common Sandpipers Actitis hypoleucos: living at the edge: Capsule Common Sandpiper populations at the edge of their range do not recruit so well.
