Age-dependent timing and routes demonstrate developmental plasticity in a long-distance migratory bird

Mo A. Verhoeven et al.

Summary: Longitudinal tracking studies on black-tailed godwits reveal that juvenile birds exhibit different migration patterns compared to adults, with timing of departure related to hatch date but other migration characteristics unrelated to hatch date or year, timing of migration, or sex. Juveniles show different migratory patterns and higher mortality rates compared to adults, but there is no evidence that these behaviors are under natural selection, suggesting that developmental plasticity allows for changes in migration behavior later in life in response to environmental conditions.

Top-down effects override climate forcing on reproductive success in a declining sea duck

Markus Ost et al.

Summary: The study demonstrates that population performance is influenced by both predator-prey relationships and climate change, with potential negative impacts on the population as predation increases and climate warming effects weaken. The interacting effects of climate and biotic interactions on population dynamics underline the complexity of ecological responses to environmental changes.

Individual repeatability of avian migration phenology: A systematic review and meta-analysis

Kirsty A. Franklin et al.

Summary: For migratory species, research shows that there are consistent individual differences in migratory timings, which depend on factors such as environmental conditions and study design. Departure from non-breeding grounds has higher repeatability than arrival at or departure from breeding grounds, indicating that factors encountered during migration and breeding outcomes can influence individual variation. Population-level shifts in phenology may result from changes in individual timings and/or shifts in the composition of individuals with different timings. Investigating the causes of between-individual variation is key to predicting future changes in migratory timings. The lack of studies in tropical regions makes it unclear what the level of repeatability is in less strongly seasonal environments.

Effects of COVID-19 lockdowns on shorebird assemblages in an urban South African sandy beach ecosystem

Jemma Lewis et al.

Summary: This study reveals the impact of human activities on bird abundance in coastal ecosystems, with human exclusion during the COVID-19 lockdown leading to an increase in bird numbers, which then declined after the lockdown was eased.

Wave-riding and wave-passing by ducklings in formation swimming

Zhi-Ming Yuan et al.

Summary: The study reveals that waterfowl can save energy expenditure through wave-riding and wave-passing when swimming in formation, achieving a delicate dynamic equilibrium. These mechanisms provide new insights into the reasons behind the evolution of swimming formation by waterfowl.

COVID-19 lockdown reveals tourists as seabird guardians

Jonas Hentati-Sundberg et al.

Summary: The lockdowns during the COVID-19 pandemic provided a rare opportunity to observe the impact of human presence on ecosystems, with a study revealing a previously concealed guarding effect by tourist groups on a seabird colony in the Baltic Sea. The absence of tourists in 2020 led to increased presence of white-tailed eagles, higher disturbance of breeding common murres, and lower murre productivity compared to the long-term average. The findings suggest that human presence could be utilized as a strategic measure in protecting seabird colonies.

Eiders, nutrients and eagles: Bottom-up and top-down population dynamics in a marine bird

Federico Morelli et al.

Summary: This long-term study aimed to identify the underlying factors contributing to the declining trend in eider population in the Baltic/Wadden Sea. The results suggest that the population was regulated by both top-down predation by white-tailed sea eagles on incubating females and bottom-up effects of nutrient levels affecting mussel stocks and eider reproduction success. The interaction between these factors may explain the decreasing population trend observed in recent decades.

Nesting Synchrony and Clutch Size in Migratory Birds: Capital versus Income Breeding Determines Responses to Variable Spring Onset

Anna Ejsmond et al.

Summary: The study presents a theoretical model for capital breeders and income breeders, finding that capital breeding birds exhibit less synchronous breeding, smaller clutch size, and higher chances for offspring recruitment when nesting is advanced; while income breeding birds do not change nesting synchrony but increase clutch size with earlier breeding.
