Migration mortality in birds

Bird migration is one of the greatest wildlife spectacles, producing massive global changes in distributions birds twice each year. To understand evolution this phenomenon, it important to know costs these journeys terms mortality they impose. The use mark/re‐sighting and tracking studies has now made possible, for some bird species, separate during from stationary periods. This paper aims assess information, based mainly on 31 published studies, most which concern long‐distance migrations passerines, large waterfowl raptors. Most revealed that rates were greater than at other times – species more 20 greater. Overall, basis median values, per unit time autumn was about 3.0 periods, spring 6.3 greater, combined 4.4 overall largely associated with adverse wind conditions autumn.

An annual cycle perspective on energetics and locomotion of migratory animals

Journal of Experimental Biology, Journal Year: 2025, Volume and Issue: 228(Suppl_1)

ABSTRACT Animal migrations, or long-distance movements, on land, through water in the air, are considered energetically costly because of investment persistent locomotion typical for migration. Diverse strategies exist to manage these energetic costs. Yet migration is only one stage an annual cycle and may not be most costly. To better understand how free-ranging animals adaptively organize energy expenditure locomotion, perspective needed. Bio-logging data collected a range animal species could facilitate life approach study expenditure. We provide examples from several studies across different taxa, as well more in-depth exploration our own recent research time activity budgets based field observations bio-logging estimate daily migratory seabird throughout year. Our has shown that highest (1.7× average expenditure) during spring gulls, whereas short-distance migrants expend (1.4× breeding season.

Distance doesn't matter: migration strategy in a seabird has no effect on survival or reproduction

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 290(1997)

Published: April 18, 2023

Migrating animals show remarkable diversity in migration strategies, even between individuals from the same population. longer distances is usually expected to be costlier terms of time, energy expenditure and risks with potential repercussions for subsequent stages within annual cycle. Such costs are balanced by increased survival, example due higher quality wintering areas or lower at latitudes. We compared reproductive parameters apparent survival lesser black-backed gulls (

Unexpected divergence in magnetoreceptor MagR from robin and pigeon linked to two sequence variations

动物学研究, Journal Year: 2023, Volume and Issue: 45(1), P. 69 - 78

Published: Nov. 30, 2023

Birds exhibit extraordinary mobility and remarkable navigational skills, obtaining guidance cues from the Earth's magnetic field for orientation long-distance movement. Bird species also show tremendous diversity in navigation strategies, with considerable differences even within same taxa among individuals population. The highly conserved iron iron-sulfur cluster binding magnetoreceptor (MagR) protein is suggested to enable animals, including birds, detect geomagnetic navigate accordingly. Notably, MagR implicated other functions, such as electron transfer biogenesis of clusters, raising question whether variability exists its biochemical biophysical features species, particularly birds. In current study, we conducted a comparative analysis two different bird migratory European robin homing pigeon. Sequence alignment revealed an extremely high degree similarity between MagRs these only three sequence variations. Nevertheless, variations underpinned significant metal capacity, oligomeric state, properties. These findings offer compelling evidence marked avian potentially explaining how can mediate diverse functions.

The underlying causes of differential migration: assumptions, hypotheses, and predictions

Published: Nov. 10, 2024

Mechanisms governing the migratory decisions of birds have long fascinated ecologists and sparked considerable debate. Identifying factors responsible for variation in migration distance, also known as differential migration, has been a popular approach to understanding mechanisms underlying behaviour more generally. However, research progress slowed by continued testing overlapping, non-mechanistic, circular predictions among small set historically entrenched hypotheses. We highlight body size hypothesis suggest that commonly tested impeded because relationships with distance are made several distinct hypotheses contrasting mechanisms. The cost itself not adequately accounted most hypotheses, we propose two flight efficiency time- energy-minimizing allow individuals mitigate risks inherent longer migrations. advance conceptual versions social dominance based on related minimization food maximization will help clarify role competition driving decisions.

Shorter Migration Distance and Breeding Latitude Correlate With Earlier Egg‐Laying Across the Northeastern Pacific Ocean Range of the Rhinoceros Auklet (Cerorhinca monocerata)

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(10)

Published: Oct. 1, 2024

Models of migratory behavior predict trade-offs between fitness costs and benefits with respect to migration distance. Shorter distances may confer a benefit by facilitating earlier breeding, however this is rarely investigated. We tested hypothesis using large-scale geolocation (GLS) dataset from 109 rhinoceros auklets (

Migration in uncertain times

Abstract Understanding the conditions that promote evolution of migration is important in ecology and evolution. When environments are fixed there one most favorable site, to other sites lowers overall growth rate not favored. Here we ask, can environmental variability favor when best site on average? Previous work suggests answer yes, but a general precise remained elusive. establish new, rigorous inequalities show (and use simulations illustrate) how stochastic increase with fitness (dis)advantages fluctuate over time across sites. The effect between depends difference expected rates variance fluctuating rates. fluctuations (variance) large, population benefit from bursts higher worse average. Such become more probable as between-site increases. Our results apply many (≥ 2) sites, reveal an interplay length paths average differences site-specific rates, size fluctuations. findings have implications for evolutionary biology they provide departure reduction principle, ecological dynamics: even superior sea poor habitats, habitat quality space determine importance migration.
