There is now abundant evidence for a role of social learning and culture in shaping behaviour range avian species across multiple contexts, from migration routes geese foraging crows, to passerine song. Recent emerging has further linked fitness outcomes some birds, highlighting its potential importance conservation. Here, we first summarize the state knowledge on focusing best-studied contexts migration, foraging, predation We identify extensive gaps taxa but argue that existing suggests that: (i) are taxonomically clustered (ii) reliance one behavioural domain does not predict others. Together, use this build predictive framework aid conservationists species-specific decision-making under imperfect knowledge. Second, review link between conservation birds. understanding which behaviours birds likely learn socially can help refine strategies, improving trajectories threatened populations. Last, present practical steps how consideration be integrated into actions including reintroductions, translocations captive breeding programmes.This article part theme issue 'Animal culture: changing world'.

The regulatory basis of migratory behaviour in birds: different paths to similar outcomes

Journal of Avian Biology, Год журнала: 2024, Номер unknown

Animal migration is a fascinating phenomenon that has puzzled mankind since the time of ancient Greece. It process widespread across varied range taxa and it shines especially in birds which, because their mobility, display an amazing diversity routes strategies. With advances tracking devices improvements sequencing technologies, recent work provides support for strong genetic influence several migratory traits different species. However, there little to no evidence any common sequence‐based mechanism behind this complex behaviour, nor unifying principle explaining it. We review how focus understanding basis should be shifted towards studying regulatory mechanisms gene expression instead traditional candidate approach. Importantly, role as underlying driver phenotype can resolve opposing often views mainly either under or environmental influence. emphasise research take new directions, reinforcing probably not regulated birds. Here, we notion 1) only evolve fast if quantitative trait with large standing variation; 2) main drivers evolution seem diverse expression–regulation rather than gene‐level polymorphisms; 3) non‐coding sequences genome, epigenetics structural variation might more important shaping previously thought. Further, present hypotheses outlining these bird species defining certain traits.

The T-DBSCAN Algorithm for Stopover Site Identification of Migration Birds Based on Satellite Positioning Data

Biology, Год журнала: 2025, Номер 14(3), С. 277 - 277

Опубликована: Март 7, 2025

With the acceleration of social development and urbanization, birds’ natural habitats have been greatly disturbed threatened. Satellite tracking technology can collect much bird activity data, providing important data support for habitat protection research. However, satellite are usually characterized by discontinuity, extensive periods, inconsistent frequency, which challenges cluster analysis. Habitat research frequently employs clustering techniques, but conventional algorithms struggle to adjust these features, particularly when it comes time dimension changes irregular sampling. T-DBSCAN, an enhanced algorithm, is suggested accommodate this intricate need. T-DBSCAN improved based on traditional DBSCAN combines a quadtree structure optimize efficiency spatial partitioning introduces convex hull algorithmic strategy perform boundary identification processing, thus improving accuracy algorithm. made account efficiently uniformity sampling in dimension. Tests demonstrate that algorithm outperforms processing techniques. It also manage large amounts discontinuous making dependable tool studying habitats.

Do first-time avian migrants know where they are going: the clock-and-compass concept today

Frontiers in Physiology, Год журнала: 2025, Номер 16

Опубликована: Апрель 15, 2025

What if your life depended on finding a place you’ve never been—without GPS device, guide, or any way of knowing where to go? For young songbirds, this is the reality their first migration. While once puzzled researchers studying bird migration, advances in field have since uncovered that many songbirds rely an inherited genetic program guide remarkable solo journeys. Today, most widely accepted theory explaining how birds species migrate solitary and do not follow experienced conspecifics find wintering grounds ‘clock-and-compass’ concept. According concept, naïve migrants certain compass direction for pre-defined period. In simplest case, when runs out, they themselves species-specific non-breeding range. However, recent research suggests process might be significantly more complex. New data indicate first-time may complete map but rather system beacons. This could based, example, geomagnetic cues other help first-year navigate location along migration route. To date, significant body evidence has been gathered revise classic ‘clock compass’ program. It likely (although perhaps all) are capable varying degrees control based innate information. The question what sources use precise remains open further investigation.

ABSTRACT Rapid developments in animal‐tracking technology have enabled major advances the field of movement ecology, which seeks to understand drivers and consequences across scales, taxa, ecosystems. The has made ground‐breaking discoveries, yet majority studies ecology remain reliant on observational approaches. While important, are limited compared experimental methods that can reveal causal relationships underlying mechanisms. As such, we advocate for a renewed focus approaches animal ecology. We illustrate way forward two fundamental levels biological organisation: individuals social groups. then explore application experiments study anthropogenic influences wildlife movement, enhance our mechanistic understanding conservation interventions. In each these examples, draw upon previous research effectively employed approaches, while highlighting outstanding questions could be answered by further experimentation. conclude ways manipulations both laboratory natural settings provide promising generate understandings drivers, consequences, movement.

Lunar synchrony, geography, and individual clocks shape autumn migration timing in an avian migrant

Behavioral Ecology, Год журнала: 2024, Номер 35(2)

Опубликована: Янв. 17, 2024

Abstract Timing programs in animal migrants have been selected to synchronize movements that coincide with predictable resources on the breeding and nonbreeding grounds. Migrants face potential temporal conflicts if their migration schedules benefit from synchrony conflicting rhythms associated annual biogeographical (circannual) cues, lunar (circalunar) or individually repeatable internal clocks. We repeat-tracked individuals of an avian lunaphilic species, Eastern Whip-poor-will (Antrostomus vociferus), for two three successive autumn migrations determine influence cycle, location, individual repeatability timing. Almost all birds avoided departing during a full moon, likely take advantage bright moonlight facilitate visual foraging enhance pre-migration fattening. However, groups latitudinally distant sampling areas adjusted departure timing differently relative September presumably due differences seasonal prey availability. Individual increased throughout migration, suggesting factors responsible shaping may differ different stages. Our results, synchrony, local climate, clocks appeared account much variation whip-poor-wills, underscore value measuring potentially interacting shape migratory behavior at group, levels. It remains unclear if, how, maintaining provides adaptive whip-poor-wills other migrants. Further clarifying reasons phenotypic whip-poor-will will improve predictions abilities adjust under changing environmental conditions.

Revisiting Perdeck's massive avian migration experiments debunks alternative social interpretations

Biology Letters, Год журнала: 2024, Номер 20(7)

Опубликована: Июль 1, 2024

Whether avian migrants can adapt to their changing world depends on the relative importance of genetic and environmental variation for timing direction migration. In classic series field experiments migration, A. C. Perdeck discovered that translocated juveniles failed reach goal areas, whereas adults performed ‘true-goal navigation’. His translocations > 14 000 common starlings ( Sturnus vulgaris ) suggested mechanisms guide into a population-specific direction, i.e. ‘vector However, alternative explanations involving social learning after release in could not be excluded. By adding historical data from translocation sites, was unavailable Perdeck's days, by integrated analyses including original data, we explain juvenile migrations possible information upon release. Despite highly behaviour, our findings are consistent with idea follow inherited independently winter quarters. Similar more solitarily migrating songbirds, would require change adjust migration route response global change.
