The BTO's Retrapping Adults for Survival scheme is designed to monitor survival rates of species of conservation concern that are monitored relatively poorly by other forms of ringing. Here we present temporal trends in survival rates for three hirundine species, Barn Swallow Hirundo rustica, House Martin Delichon urbicum and Sand Martin Riparia riparia. Estimates of apparent survival rate were similar to those found in previous studies and were correlated with rainfall on the African wintering… Expand
Apparent survival rates of two Sylvia warbler species in northwestern Russia
Mark–recapture ringing data from two sites in northwestern Russia were used to estimate apparent survival rates in populations of Garden Warbler Sylvia borin and Whitethroat S. communis. The computerExpand
Apparent Constant Adult Survival of a Sand Martin Riparia riparia Population in Relation to Climatic Variables
TLDR
It is suggested that the relationship with rainfall no longer holds, and that current population declines may be unrelated to climate in the winter quarters. Expand
Density-dependent survival and recruitment in a long-distance Palaearctic migrant, the Sand Martin Riparia riparia
Long-term studies can provide powerful insights into the relative importance of different demographic and environmental factors determining avian population dynamics. Here we use 23 years ofExpand
Rainfall on wintering grounds affects population change in many species of Afro-Palaearctic migrants
AbstractSurvival and population growth rates in several species of Afro-Palaearctic migrant have been shown to correlate with rainfall regimes and/or vegetation level on their African winteringExpand
Local survival rates of Pied Flycatchers Ficedula hypoleuca depend on their immigration status
Chernetsov, N., Sokolov, L.V. & Kosarev, V. (2009): Local survival rates of Pied Flycatchers Ficedula hypoleuca depend on their immigration status. Avian Ecol. Behav. 16: 11-20. We estimated annualExpand
Demographic response to environmental variation in breeding, stopover and non-breeding areas in a migratory passerine
TLDR
Red-backed shrikes’ population dynamics are driven by environmental factors operating at various scales of space and time, but only a small amount of the temporal variation in demographic rates is explained by the environmental factors considered, suggesting that additional factors, such as those operating during migration, might be important. Expand
High within‐winter and annual survival rates in a declining Afro‐Palaearctic migratory bird suggest that wintering conditions do not limit populations
TLDR
The findings suggest that the wintering grounds do not limit populations as much as the migratory and breeding stages, with implications for the conservation of declining Afro-Palaearctic migrants more widely. Expand
Maintenance of livestock farming may buffer population decline of the Barn Swallow Hirundo rustica
Summary Populations of farmland and long-distance migratory birds have suffered steep, often dramatic, declines in the last few decades. The Barn Swallow Hirundo rustica is a small migratory farmlandExpand
Bird ringing in Britain and Ireland in 2007
TLDR
The 25th year of Constant Effort Site (CES) ringing demonstrated how the heavy rainfall during the summer of 2007 had a largely negative effect on breeding success, with productivity of ten species significantly lower than the long‐term average, although that of four species was significantly higher. Expand
Temperature and precipitation effects on breeding productivity of some passerines – a multivariate analysis of constant effort mist-netting data
TLDR
The results of this study have shown that the high April and May temperature has been favourable for the breeding of the partial and the short-distance migrants, the common blackbird (Turdus merula) and the Eurasian blackcap (Sylvia atricapilla). Expand

Survival of British Sedge Warblers Acrocephalus schoenobaenus in relation to west African rainfall
Fluctuations in the population levels and annual adult survival rates of British Sedge Warblers Acrocephalus schoenobaenus since the late 1960s are strongly correlated with indices of wet seasonExpand
Variation in the survival rates of some British passerines with respect to their population trends on farmland
TLDR
New analyses of survival rates, using British ring-recovery data from 1962 to 1995, for 31 farmland passerine species, show whether effects on survival have occurred which are consistent with their being an important mechanism mediating the effects of the environment on abundance. Expand
Population trends of Swallows Hirundo rustica breeding in Britain
TLDR
Although Swallow numbers show large annual fluctuations, there is no evidence for a long-term decline on CBC plots, and changes in breeding location may mean local declines are not reflected in regional or national population trends. Expand
Long-term variation in survival rates of Sand Martins Riparia riparia: dependence on breeding and wintering ground weather, age and sex, and their population consequences
TLDR
The importance of rainfall on the breeding grounds as a negative influence on over-winter survival is a novel finding both in Sand Martin biology and in the context of the environmental influences on passerine demography in general. Expand
SEASONAL FLUCTUATIONS IN RAINFALL, FOOD AND ABUNDANCE OF TROPICAL INSECTS
TLDR
It is shown that, especially for those groups of Homoptera that have nymphs feeding on the foliage, there is a good relation between leaf production and the demography of the species concerned. Expand
The use of constant effort mist-netting to measure between-year changes in the abundance and productivity of common passerines
TLDR
For most of the species considered there was little evidence that between-year changes in catches of adults at CE sites have differed between habitats, and predictions are made concerning likely improvements in precision from a larger CES Scheme. Expand
Relationship between west African rainfall and the survival of central European sand martins Riparia riparia
TLDR
Differences in the changes of the population size and adult survival rate showed the importance of the recruitment of adults, and this may depend mainly on the survival of juveniles. Expand
Tropical Avian Phenology in Relation to Abundance and Exploitation of Food Resources
TLDR
It is suggested that arthropod abundance is a crucial factor governing the timing of breeding activities, even in species that normally include a high proportion of nectar and fruits in their diet, and that, in tropical habitats receiving > 1500 mm of rain per year, breeding in nectarivores and frugivores in the dry season may be related to the lower reduction inArthropod numbers over the less severe drought period.

Winter Habitat Quality, Population Limitation, and Conservation of Neotropical‐Nearctic Migrant Birds
TLDR
Results of research on paruline warblers in Jamaica indicate that migrant passerines often compete intraspecifically in winter for preferred quality habitats and that their populations may be limited at least in part by ecological conditions in winter. Expand
Effects of spring drought and irrigation on farmland arthropods in southern Britain
TLDR
It is suggested that automated rain shielding of experimental plots provides a technique for wider application in drought studies and illustrates that spring weather might affect the availability of arthropod prey for insectivorous wildlife. Expand
