Annual routines of migratory birds inferred from archival solar geolocation devices have never before been confirmed using GPS technologies. A female black‐tailed godwit Limosa limosa captured on the breeding grounds in Netherlands 2013 and recaptured 2014 was outfitted with both an Intigeo geolocator UvA‐BiTS GPS‐tracker. The positions show that, after its season 2013, flew 2035 km nonstop to southern Spain. It then spent entire nonbreeding part Iberian Peninsula returning following spring,...
Nearly 20% of all bird species migrate between breeding and nonbreeding sites annually. Their migrations include storied feats endurance physiology, from non-stop trans-Pacific crossings to flights at the cruising altitudes jetliners. Despite intense interest in these performances, there remains great uncertainty about which factors most directly influence behaviour during migratory flights. We used GPS trackers that measure an individual's altitude wingbeat frequency track migration...
Summary Extreme weather events have the potential to alter both short‐ and long‐term population dynamics as well community‐ ecosystem‐level function. Such are rare stochastic, making it difficult fully document how organisms respond them predict repercussions of similar in future. To improve our understanding mechanisms by which short‐term can incur consequences, we documented behavioural responses fitness consequences for a long‐distance migratory bird, continental black‐tailed godwit...
In seasonal environments, increasing spring temperatures lead many taxa to advance the timing of reproduction. Species that do not may suffer lower fitness. We investigated why black-tailed godwits (Limosa limosa limosa), a ground-breeding agricultural grassland shorebird, have advanced reproduction during last three decades in face climate change and human-induced habitat degradation. used data from an 11-year field study parameterize Integral Projection Model predict how temperature...
Over the past 50 years, population of Continental Black-tailed Godwits Limosa limosa breeding East Atlantic Flyway has been in steep decline. This decline previously documented trend analyses and six Netherlands-wide count-based estimates, last which was completed 1999. We provide an updated size estimate describe inter-annual fluctuations between 2007 2015. To generate these we integrated a mark-recapture survival analysis with estimates densities colour-marked individuals at migratory...
Few studies have been able to directly measure the seasonal survival rates of migratory species or determine how variable timing migration is within individuals and across populations over multiple years. As such, it remains unclear likely affect population dynamics capable migrants may be responding changing environmental conditions their lifetimes. To address these questions, we used three types tracking devices track individual black-tailed godwits from nominate subspecies (Limosa limosa...
Longitudinal tracking studies have revealed consistent differences in the migration patterns of individuals from same populations. The sources or processes causing this individual variation are largely unresolved. As a result, it is mostly unknown how much, fast and when animals can adjust their migrations to changing environments. We studied ontogeny long-distance migratory shorebird, black-tailed godwit Limosa limosa limosa, species known exhibit marked individuality routines adults. By...
Habitat loss and shifts associated with climate change threaten global biodiversity, impacts likely to be most pronounced at high latitudes. With the disappearance of tundra breeding habitats, migratory shorebirds that breed these latitudes are even more vulnerable than those in temperate regions. We examined this idea using new distributional information on two subspecies Black-tailed Godwits Limosa limosa Asia: northerly, bog-breeding L. l. bohaii southerly, steppe-breeding melanuroides....
ABSTRACT Aim We develop and test a cost framework to simulate the flyways of migratory seabirds, considering various environmental factors such as wind support, crosswind, travel distance, food availability. Using this framework, we potential for arctic terns compare these simulations with tracking data. Our aim is identify which combination best explains observed flyways. Ultimately, seek demonstrate how different shape Innovation simulated 195 possible seabird using newly developed...
Variation in migratory behaviour is the result of different individual strategies and fluctuations performances. A first step toward understanding variation among individuals therefore to assess relative contributions inter- intra-individual differences this variation. We did using light-level geolocators deployed on breeding grounds follow continental black-tailed godwits (Limosa limosa limosa) throughout both their south- northward migrations over multiple years. Based repeated tracks from...
The adult sex ratio (ASR) is a crucial component of the ecological and evolutionary forces shaping dynamics population. Although in many declining populations ASRs have been reported to be skewed, empirical studies exploring demographic factors are still rare. In this study socially monogamous sexually dimorphic Black-tailed Godwit (Limosa limosa limosa), we aim evaluate chicks at hatch subsequent sex-specific survival differences occurring over 3 life stages. We found that, hatch, did not...
Abstract Animals must balance various costs and benefits when deciding to breed. The of breeding at different times have received much attention, but most studies been limited investigating short‐term season‐to‐season fitness effects. However, early, versus late, in a season may influence lifetime over many years, trading off complex ways across the breeder’s lifespan. In this study, we examined complete life histories 867 female tree swallows ( Tachycineta bicolor ) Ithaca, New York,...
Abstract Migrating long distances requires time and energy, may interact with an individual's performance during breeding. These seasonal interactions in migratory animals are best described populations disjunct nonbreeding distributions. The black‐tailed godwit ( Limosa limosa ), which breeds agricultural grasslands Western Europe, has such a distribution: majority spend the season West Africa, while growing number winters north of Sahara on Iberian Peninsula. To test whether crossing...
Sexual size dimorphism ( SSD ) is common in birds and has been linked to various selective forces. Nevertheless, the question of how when sexes start differentiate from each other poorly studied. This a critical knowledge gap, as sex differences growth may cause different responses similar ecological conditions. In this study, we describe sex‐specific – based on body mass five morphometric measurements 56 captive Black‐tailed Godwit Limosa limosa chicks raised under ad libitum food...
In response to environmental change, species have been observed altering their migratory behaviours. Few studies, however, able determine whether these alterations resulted from inherited, plastic or flexible changes. Here, we present a unique observation of rapid population-level shift in routes—over 300 km Spain Portugal—by continental black-tailed godwits Limosa limosa . This did not result adult changing staging sites, as site use was highly consistent. Rather, the young predominantly...
Long‐term population studies can identify changes in dynamics over time. However, to realize meaningful conclusions, these rely on accurate measurements of individual traits and characteristics. Here, we evaluate the accuracy observational methods used measure reproductive individually marked black‐tailed godwits ( Limosa limosa ). By comparing estimates from traditional with data obtained light‐level geolocators, provide an estimate likelihood renesting repeatability lay dates first...
Abstract In this paper, we extend our understanding of the migration Black-tailed Godwits ( Limosa limosa ) by describing: (1) orientation and geographic locations individual migratory routes (2) spatial distribution godwits across seasons years. We accomplish using satellite-tracking data from 36 adult breeding in 200-ha Haanmeer polder The Netherlands, 2015 to 2018. During both southward northward migration, used a narrow corridor along which most individuals made stops within network...
In an attempt to encourage the discourse on sources of individual variation in seasonal migration patterns and microevolution bird migration, we here critically examine published interpretations a now classic displacement study with starlings Sturnus vulgaris . Based ring recoveries after experimental towards south southeast Dutch capture sites over 18 000 hatch‐year older starlings, series analyses Ardea from 1958 1983, A. C. Perdeck established that displaced showed appropriately changed...
The miniaturization of tracking devices is now rapidly increasing our knowledge on the spatiotemporal organization seasonal migration. So far, most studies aimed at understanding within- and between-individual variation in migratory routines focus single populations. This has also been case for continental Black-tailed Godwits Limosa l. limosa (hereafter Godwits), with work carried out individuals from Dutch breeding population, migrating relatively large numbers westernmost part range. Here...
As is the case for most avian species, there considerable variation in egg size of Continental Black-tailed Godwits Limosa l. limosa breeding The Netherlands. It interesting that has costs and benefits yet varies considerably at population level. To better understand this size, we tested its relationship to a suite individual environmental factors. We found can decrease up 2.8% throughout season increases with clutch by 1.4% each additional clutch. Female body mass explained 5% total...
Abstract Misidentification of marked individuals is unavoidable in most studies wild animal populations. Models commonly used for the estimation survival from such capture–recapture data ignore misidentification errors potentially resulting biased parameter estimates. With a simulation study, we show that ignoring Cormack–Jolly–Seber (CJS) models results systematic positive biases estimates and spurious declines over time. We developed an extended robust design capture mark–resight (RDM)...
The departure of migratory birds from their non-breeding grounds is thought to be driven by the phenology breeding destination. In north-west Australia, two plumage morphs Red Knot (Calidris canutus) prepare for a 5500-kmjourney Yellow Sea staging areas. These are recognised as subspecies C. c. piersmai and rogersi, which breed at different latitudes have seasonalities. From February May 2011, we observed preparation individually marked known age, sex type. This enabled comparison fuelling...
