Among birds, the Procellariiform seabirds (petrels, albatrosses, and shearwaters) are prime candidates for using chemical cues individual recognition. These birds have an excellent olfactory sense, a variety of species nest in burrows that they can recognize by smell. However, nature signature--the scent makes one burrow smell more like home than another--has not been established any species. Here, we explore use intraspecific recognition present evidence partner-specific odor bird.

Pelagic birds, which wander in the open sea most of year and often nest on small remote oceanic islands, are able to pinpoint their breeding colony even within an apparently featureless environment, such as ocean. The mechanisms underlying surprising navigational performance still unknown. In order investigate nature cues exploited for navigation, Cory's shearwaters, Calonectris borealis, nesting Azores were displaced released ocean at about 800 km from colony, after being subjected sensory...
Mate choice for major histocompatibility complex (MHC) compatibility has been found in several taxa, although rarely birds. MHC is a crucial component adaptive immunity and by choosing an MHC-dissimilar partner, heterozygosity potentially broad pathogen resistance maximized the offspring. The genotype influences odour cues preferences mammals fish hence olfactory-based mate can occur. We tested whether blue petrels, Halobaena caerulea , choose partners based on compatibility. This bird...
Petrels, albatrosses and other procellariiform seabirds have an excellent sense of smell, routinely navigate over the world's oceans by mechanisms that are not well understood. These birds travel thousands kilometres to forage on ephemeral prey patches at variable locations, yet they can quickly efficiently find their way back nests remote islands provision chicks, even with magnetic senses experimentally disrupted. Over seemingly featureless ocean environment, local emissions scents...
We report the first successful use of miniature Global Positioning System loggers to track ocean‐going behaviour a c . 400 g seabird, Manx Shearwater Puffinus puffinus Breeding birds were tracked over three field seasons during incubation and chick‐rearing periods on their foraging excursions from large colony Skomer Island, Pembrokeshire, UK. Foraging effort was concentrated in Irish Sea. Likely areas identified north, more diffusely west colony. No recorded significantly south colony,...
Albatrosses do something that no other birds are able to do: fly thousands of kilometres at mechanical cost. This is possible because they use dynamic soaring, a flight mode enables them gain the energy required for flying from wind. Until now, physical mechanisms in terms transfer wind bird were mostly unknown. Here we show achieved by manoeuvre consisting continually repeated up-down curve with optimal adjustment We determined obtained analysing measured trajectories free using new...
Dynamic soaring is a small-scale flight manoeuvre which the basis for extreme performance of albatrosses and other large seabirds to travel huge distances in sustained non-flapping flight. As experimental data with sufficient resolution these movements are not available, knowledge lacking about dynamic physical mechanism energy gain bird from wind. With new in-house developments GPS logging units recording raw phase observations dedicated mathematical method postprocessing measurements, it...
Many animals are known to preferentially mate with partners that dissimilar at the major histocompatibility complex (MHC) in order maximize antigen binding repertoire (or disease resistance) their offspring. Although several mammals, fish or lizards use odour cues assess MHC similarity potential partners, ability of birds using olfactory has not yet been explored. Here we used a behavioural binary choice test and high-throughput-sequencing class IIB determine whether blue petrels can...
Abstract Pelagic seabirds wander the open oceans then return accurately to their habitual nest-sites. We investigated effects of sensory manipulation on oceanic navigation in Scopoli’s shearwaters ( Calonectris diomedea ) breeding at Pianosa island (Italy), by displacing them 400 km from colony and tracking them. A recent experiment Atlantic (Cory’s shearwater, borealis Azores indicated a crucial role olfaction over ocean, but left question whether birds might navigate topographical landmark...
Significance Penguins have long been of interest to scientists and the general public, but their evolutionary history remains unresolved. Using genomes, we investigated drivers penguin diversification. We found that crown-group penguins diverged in early Miocene Australia/New Zealand identified Aptenodytes (emperor king penguins) as sister group all other extant penguins. first occupied temperate environments then radiated cold Antarctic waters. The Circumpolar Current’s (ACC)...
Differences in visual capabilities are known to reflect differences foraging behaviour even among closely related species. Among birds, the of diurnal raptors is assumed be guided mainly by vision but their tactics include both scavenging upon immobile prey and aerial pursuit highly mobile prey. We studied how differ between two raptor species similar size; Harris's Hawks Parabuteo unicinctus, which take prey, Black Kites Milvus migrans, primarily carrion eaters. measured acuity, foveal...
In nearly every procellariiform species, the sense of smell appears to be highly adapted for foraging at sea, but among diving petrels is enigmatic. These birds forage considerable depth and are not attracted odour cues sea. However, several species have recently been shown relocate their nesting burrows by scent, suggesting that these use an olfactory signature identify home burrow. We wanted know whether in this way. tested common petrel Pelecanoides urinatrix South-Georgian georgicus...
Many burrowing petrels are able to return their nests in complete darkness. The well-developed anatomy of olfactory system and the attraction that food-related odour cues have for some petrel species suggest olfaction may be used recognize burrow. In contrast, surface-nesting rely on visual recognise nest. We performed experiments nine (with different nesting habits) rendered anosmic either by plugging nostrils or injecting zinc sulphate onto nasal epithelium. Compared with shamtreated...
Avian chemosignaling remains relatively unexplored, but its potential importance in birds' social behaviors is becoming recognized. Procellariiform seabirds provide particularly appropriate models for investigating these topics as they possess a well-developed olfactory system and unequalled associated capabilities. We present here results from detailed chemical examination of the uropygial secretions (the main source avian exogenous chemicals) 2 petrel species, Antarctic prions blue...
