“…Changes in the migratory phenology due to climate change have been observed in other bird species Ward et al, 2009;Møller et al, 2010;Lehikoinen et al, 2013;Martín et al, 2014;Kullberg et al, 2015). In the case of the common quail, first spring arrivals to northern Spain have been experiencing a shift towards earlier dates (data from 1983 to 2004), in line with an increase in mean temperature in the sub-Saharan strip where the main wintering grounds are located (Rodríguez-Teijeiro et al, 2005).…”

Background:The common quail, Coturnix coturnix, is a migratory bird hunted extensively across Europe. To satisfy this hunting interest, thousands of farm-reared birds are restocked every year. However, restocked individuals are not common quail but hybrids with domestic Japanese quail, C. japonica. Interbreeding between restocked and native birds in the wild allows the entry of alien alleles to the native populations, which could lead to the loss of adaptive phenotypes and behaviours, such as migratory drive. Sedentary individuals may face wintering conditions to which they are not adapted, suffering higher mortality. Some individuals have been observed to remain in northern latitudes during winter.Question: Does game restocking contribute to the sedentarization of the common quail population?Method: We sampled 42 quail during the autumn migration and 50 quail during winter in Spain. We genetically analysed them using a set of autosomal microsatellites and also sequenced a fragment of the mitochondrial DNA control region. We evaluated the proportion of admixed quail found and compared it with that previously found in a breeding population.Results: None of the migratory quail were admixed individuals, although two of them showed introgression of Japanese mitochondrial DNA. Among wintering quail, only three individuals had a genetic composition compatible with a farm origin, while the rest were common quail. Thus, the proportion of admixed quail during winter was not higher than during the breeding season.Conclusion: Restocking individuals with domestic Japanese quail ancestry is not directly associated with the presence of quail during winter in northern latitudes. The almost complete absence of individuals of farm origin among the migratory and wintering quail populations indicates that the vast majority of the restocked individuals probably die soon after release.

“…For example, structured arrival and breeding schedules of long‐distance migrants have resulted in phenological mismatches as seasonal resource availability on the breeding grounds changes as a result of climate change (Both et al ., ; Møller et al ., ; Saino et al ., ). In general, short‐distance migrants have greater ability to adjust their migration and breeding schedules in response to gradual (Kullberg et al ., ; Travers et al ., ) or abrupt (La Sorte et al ., ) changes in seasonal resource availability. The positive relationship we documented between migration distance and en‐route variation in migratory behaviour may allow for the maintenance of structured arrival and breeding dates.…”

Aim Seasonal migration is a common strategy used by terrestrial birds that breed in temperate regions of the Northern Hemisphere. Evidence suggests that long‐distance migrants have limited flexibility in migratory behaviour during the onset of migration but greater flexibility during the migration journey. Here, we examine how two geographical factors are correlated with en‐route flexibility. Due to stronger time‐selection pressures, we expected species with longer migration distances to have greater en‐route variation, that increases when large ecological barriers to migration are present. Location Western Hemisphere. Methods We estimated annual population‐level migration trajectories for 55 terrestrial bird species over 7 years (2009–15) based on occurrence information from eBird. We calculated migration speed and annual variation in migration speed, timing and location. We examined these metrics as a function of migration distance for species in the eastern (n = 41) and western (n = 14) migration flyways. The eastern flyway contains two large ecological barriers to migration, the Gulf of Mexico and the Atlantic Ocean. Results Spring migration speeds exceeded autumn migration speeds in both flyways. Migration speeds were faster in the eastern flyway during both seasons. Annual variation in migration speed increased as migration distances increased in both flyways during both seasons. Annual variation in migration timing and location increased as migration distance increased in the eastern flyway during both seasons. In the western flyway, annual variation in migration timing and location increased as migration distance increased, but only during the autumn migration. Main conclusions Increasing time‐selection pressures related to migration distance and ecological barriers were associated with greater en‐route variation in migratory behaviour. Variation in migration speed was most consistently associated with variation in migratory behaviour, whereas variation in migration timing and location differed by season and was strongest when large ecological barriers were present. Our results suggest that the capacity to respond to environmental variation during migration increases as migration distances increase.

“…Indeed, the lack of consensus among studies examining the association between latitude and phenological shift may be partially explained by differences in spatial scale; some analyses were conducted at hemispheric scales (e.g., Northern Hemisphere; Parmesan ), while others are restricted to single countries (e.g., Sweden; Kullberg et al. ) with limited latitudinal variation.…”

Species across a wide range of taxa and habitats are shifting phenological events in response to climate change. While advances are common, shifts vary in magnitude and direction within and among species, and the basis for this variation is relatively unknown. We examine previously suggested patterns of variation in phenological shifts in order to understand the cue–response mechanisms that underlie phenological change. Here, we review what is known about the mechanistic basis for nine factors proposed to predict phenological change (latitude, elevation, habitat type, trophic level, migratory strategy, ecological specialization, species’ seasonality, thermoregulatory mode, and generation time). We find that many studies either do not identify a specific underlying mechanism or do not evaluate alternative mechanistic hypotheses, limiting the ability of scientists to predict future responses to global change with accuracy. We present a conceptual framework that emphasizes a critical distinction between environmental (cue‐driven) and organismal (response‐driven) mechanisms causing variation in phenological shifts and discuss how this distinction can reduce confusion in the field and improve predictions of future phenological change.
