To evolve and to be maintained, seasonal migration, despite its risks, has yield fitness benefits compared with year-round residency. Empirical data supporting this prediction have remained elusive in the bird literature. test related of we studied a partial migratory population European blackbirds (Turdus merula) over 7 years. Using combination capture-mark-recapture radio telemetry, survival probabilities between migrants residents estimated by multi-event models, showing that migrant had...
Infectious wildlife diseases that circulate at the interface with domestic animals pose significant threats worldwide and require early detection warning. Although animal tracking technologies are used to discern behavioural changes, they rarely monitor diseases. Common disease-induced changes include reduced activity lethargy (‘sickness behaviour’). Here, we investigated whether accelerometer sensors could detect onset of African swine fever (ASF), a viral infection induces high mortality...
Every year, billions of wild diurnal songbirds migrate at night. To do so, they shift their daily rhythm from diurnality to nocturnality. In captivity this is observed as a gradual transition daytime activity developing into nocturnal activity, but how birds prepare rhythms for migration remains largely unknown. Using an automated radio-telemetry system, we compared patterns free-living migrant and resident European blackbirds (Turdus merula) in partially migratory population during the...
In a seasonal world, organisms are continuously adjusting physiological processes relative to local environmental conditions. Owing their limited heat and fat storage capacities, small animals, such as songbirds, must rapidly modulate metabolism in response weather extremes changing seasons ensure survival. As consequence of previous technical limitations, most our existing knowledge about how animals respond conditions comes from laboratory studies or field over short temporal scales. Here,...
Parasites can impact the behavior of animals and alter interplay with ecological factors in their environment. Studying effects that parasites have on thus requires accurate estimates infections individuals. However, quantifying be challenging due to several factors. Laboratory techniques, physiological fluctuations, methodological constraints, environmental influences introduce measurement errors, particular when screening individuals wild. These issues are pervasive studies where it is...
Major climatic changes in conjunction with animal movement may be associated the spread of parasites and their vectors into new populations, potentially important consequences for population persistence. Parasites can evolve to adapt unsuitable ecological conditions take up refuge within host species, growth species. One parasite species that has likely been increasing its geographic range, infecting hosts, is recently described air sac nematode Serratospiculoides amaculata, great tits...
ABSTRACT Forming collectives can generate substantial benefits, but much less is known about the costs that individuals incur in doing so. We simultaneously captured individual movement, within-group position, leadership, and heart rate for each member a group of wild vulturine guineafowl. Individuals had significantly increased rates when moving collectively, occupying more central positions within group, or attempting to initiate directional movement consensus among members was low. Such...
