Abstract Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, highly threatened, cover vast distances during foraging migration. However, spatial overlap between petrels plastics poorly understood. Here we combine...
The migratory movements of seabirds (especially smaller species) remain poorly understood, despite their role as harvesters marine ecosystems on a global scale and potential indicators ocean health. Here we report successful attempt, using miniature archival light loggers (geolocators), to elucidate the behaviour Manx shearwater Puffinus puffinus , small (400 g) Northern Hemisphere breeding procellariform that undertakes trans-equatorial, trans-Atlantic migration. We provide details...
I introduce three scenarios for the evolution of conspicuous coloration associated with unpalatability in prey animals, based on ways which selection two character types (unpalatability and coloration) may interact. consider only simple two-character-state cases. use these as a framework an analysis issues warning coloration. First, discuss generality color explanation coincidence between unpalatability. present alternative that does not involve aposematic coloration: conspicuously colored...
Abstract Aim An understanding of the non‐breeding distribution and ecology migratory species is necessary for successful conservation. Many seabirds spend season far from land, information on their during this time very limited. The black‐legged kittiwake, Rissa tridactyla , a widespread numerous seabird in North Atlantic Pacific, but breeding populations throughout range have declined recently. To help understand reasons declines, we tracked adults colonies over using light‐based...
Navigational control of avian migration is understood, largely from the study terrestrial birds, to depend on either genetically or culturally inherited information. By tracking individual migrations Atlantic Puffins, Fratercula arctica, in successive years using geolocators, we describe migratory behaviour a pelagic seabird that apparently incompatible with this view. Puffins do not migrate single overwintering area, but follow dispersive pattern movements changing through non-breeding...
Individual foraging specializations, where individuals use a small component of the population niche width, are widespread in nature with important ecological and evolutionary implications. In long-lived animals, ability develops age, but we know little about ontogeny individuality foraging. Here precision global positioning system (GPS) loggers to examine how individual site fidelity (IFSF), common specialization, varies between breeders, failed breeders immatures marine predator—the...
Abstract Population‐level estimates of species’ distributions can reveal fundamental ecological processes and facilitate conservation. However, these may be difficult to obtain for mobile species, especially colonial central‐place foragers ( CCPF s; e.g., bats, corvids, social insects), because it is often impractical determine the provenance individuals observed beyond breeding sites. Moreover, some s, in marine realm (e.g., pinnipeds, turtles, seabirds) are observe they range tens ten...
Abstract The conservation of migratory marine species, including pelagic seabirds, is challenging because their movements span vast distances frequently beyond national jurisdictions. Here, we aim to identify important aggregations seabirds in the North Atlantic inform ongoing regional efforts. Using tracking, phenology, and population data, mapped abundance diversity 21 seabird species. This revealed a major hotspot associated with discrete area subpolar frontal zone, used annually by 2.9–5...
Although it is known that birds can return to their breeding grounds with exceptional precision, has remained a mystery how they know when and where stop migrating. Using nearly century’s worth of Eurasian reed warbler ( Acrocephalus scirpaceus ) ringing recoveries, we investigated whether fluctuations in Earth’s magnetic field predict variation the sites which return. Ringing recoveries suggest inclination learned before departure subsequently used as uni-coordinate “stop sign” relocating...
ABSTRACT Aim To identify the broad‐scale oceanic migration routes (‘marine flyways’) used by multiple pelagic, long‐distance migratory seabirds based on a global compilation of tracking data. Location Global. Time Period 1989–2023. Major Taxa Studied Seabirds (Families: Phaethontidae, Hydrobatidae, Diomedeidae, Procellariidae, Laridae and Stercorariidae). Methods We collated comprehensive dataset that included 48 pelagic migrating seabird species across Atlantic, Indian, Pacific Southern...
Recently it has been shown that pyrazines are associated with many aposematic, chemically defended insects. We have demonstrated naive hatchling chicks, when offered drinking water to which 2-methoxy-3-isobutylpyrazine is added, develop a neophobic ‘alerting’ reaction. The birds not only capable of forming conditioned aversion the pyrazine paired quinine sulphate but they can also detect from distance probably by olfaction. This suggests birds, major group insect predators, interpret as...
Wide-ranging animals, such as birds, regularly traverse large areas of the landscape efficiently in course their local movement patterns, which raises fundamental questions about cognitive mechanisms involved. By using precision global-positioning-system loggers, we show that homing pigeons ( Columba livia ) not only come to rely on highly stereotyped yet surprisingly inefficient routes within area but are attracted directly back individually preferred even when released from novel sites...
Recent evidence shows that, despite earlier beliefs, many birds have a functional sense of smell. There is also considerable variation in olfactory-bulb size among bird species, yet the evolutionary significance this has remained elusive. We argue that living under low-light conditions, where vision less efficient, should evolved or maintained an increased olfactory ability and, hence, larger bulbs. Using family-level comparative analysis to control at least partially for taxonomic...
