Abstract Birds are hosts for several zoonotic pathogens. Because of their high mobility, especially longdistance migrants, birds can disperse these pathogens, affecting distribution and phylogeography. We focused on Borrelia burgdorferi sensu lato, which includes the causative agents Lyme borreliosis, as an example tick‐borne to address role propagation at a large geographical scale. collected ticks from passerine in 11 European countries. B . s.l. prevalence Ixodes spp. was 37% increased...
Abstract Although problem-solving tasks are frequently used to assess innovative ability, the extent which performance reflects variation in cognitive skills has been rarely formally investigated. Using wild breeding great tits facing a new non-food motivated task, we investigated role of associative learning finding solution, compared multiple other non-cognitive factors. We first examined accuracy (the proportion contacts made with opening part string-pulling task), neophobia, exploration,...
Abstract Foraging innovation, in which an individual eats a novel food or uses foraging technique, has been observed wide range of species. If other individuals are nearby, they may adopt the thus spreading it through population. Much research focused on this social transmission behaviour, but effect context emergence behaviour is unclear. Here, we examine innovative feeding Carib grackle (Quiscalus lugubris), opportunistic, gregarious bird. We test proximity conspecifics, while eliminating...
Wild birds that vary in their problem-solving capacity were found to express different neurotransmitter receptor densities.
Recent studies have uncovered relationships between measures of various cognitive performances and proxies fitness such as reproductive success in non-human animals. However, to better understand the evolution cognition wild, we still determine causality these underlying mechanisms. The ability an individual may directly influence its raise many and/or high quality young through for example provisioning ability. Conversely, large broods lead parental motivation solve problems related their...
Although disruption of glucose homeostasis is a hallmark ageing in humans and laboratory model organisms, we have little information on the importance this process free-living animals. Poor control blood levels leads to irreversible protein glycation. Hence, glycation are hypothesized increase with age be associated decline survival. We tested these predictions by measuring glycated haemoglobin 274 adult collared flycatchers known estimating individual probability recapture following 2...
Although most bird species show monogamous pair bonds and bi‐parental care, little is known of how mated birds coordinate their activities. Whether or not partners communicate with each other to adjust behaviour remains an open question. During incubation the first days after hatching, one parent – generally female stays in nest for extended periods, might depend on acoustic communication exchange information its mate outside. The Great Tit Parus major interesting study system investigate...
In spatio-temporally variable environments, individuals are known to use information for making optimal decisions regarding where and when breed. Optimal decision can be complex relying on multiple sources with varying levels of reliability accessibility. To deal such complexity, different cognitive abilities as learning memory might enable optimally process these sources. Yet, the link between ability remains unexplored in natural populations. We investigated whether performance a...
Recent studies suggest that individuals with better problem‐solving and/or learning performance have greater reproductive success, and may thus benefit from choosing mates based on these performances. However, directly assessing performances in candidate could be difficult. Instead, the use of indirect cues related to performance, such as condition‐dependent phenotypic traits, might favored. We investigated whether a novel non‐foraging task correlated sexually selected plumage colouration...
Abstract Background In bird species where offspring growth and survival rely on parents’ food provisioning, parents can maximise their fitness by increasing the quantity and/or quality of preys delivered to offspring. Many studies have focused inter-individual variation in feeding rate, yet this measure may not accurately reflect total amount (i.e. energy) provided if there is large at each feeding. Here, we explored relative role individual (sex, age, body condition), breeding (hatching...
During winter 2015 in Montreal (Canada), we observed on two occasions a group of House Sparrows (Passer domesticus) hiding under the body several cars, empty spaces between wheels and fender. On both occasions, it was either snowing or raining. This paper reports for first time, to our knowledge, description birds using cars shelter from rain snow. Moreover, some individuals were engaged continuous round trips car bushes, seemingly detect potential predators that would not be visible car....
Abstract Spatio-temporal variation in age structure influences population dynamics, yet we have limited understanding of the spatial scale at which its fluctuations are synchronised between populations. Using 32 great tit populations, spanning 3200km and > 130,000 birds across 67 years, quantify synchrony breeding drivers. We show that larger clutch sizes, colder winters summers, beech crops lead to younger report distant-dependent structure, is maintained approximately 650km. Despite...
Few details are available on the migration (rates, routes, dates) of Neotropical austral migrant birds, which breed and migrate wholly within South America. Only one long-distance breeds in American temperate forest biome: White-crested Elaenia (Elaenia albiceps chilensis). However, migratory dates, wintering locations poorly known. During summers 2011–2013, we attached light level geolocators to breeding Elaenias at world's southernmost forests, Navarino Island, Chile. The duration fall...
We observed Grey Kingbirds (Tyrannus dominicensis) from late February to May 2007 stealing food items the bills of Carib Grackles (Quiscalus lugubris). This behavior occurred at two baited walk-in bird traps on grounds Bellairs Research Institute McGill University in St James, Barbados. were not seen entering traps, but regularly tree branches near often chasing and Zenaida Doves (Zenaida aurita) as they exited with food. describe six instances kleptoparasitism by Grackles.
