Abstract A major barrier to advancing ornithology is the systemic exclusion of professionals from Global South. recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed long-standing pattern highlighting individuals, knowledge, views North, while largely omitting perspectives people based within Neotropics. Here, we review current strengths opportunities practice ornithology. Further, discuss problems with assessing state through northern lens, including discovery narratives, incomplete (and biased) understanding history advances, promotion agendas that, currently popular north, may not fit needs realities research. We argue that future advances will critically depend on identifying addressing barriers hold back ornithologists who live work Neotropics: unreliable limited funding, international research leadership, restricted dissemination knowledge (e.g., language hegemony citation bias), logistical barriers. Moving forward, must examine acknowledge colonial roots our discipline, explicitly promote anti-colonial for research, training, conservation. invite colleagues beyond Neotropics join us creating new models governance establish priorities vigorous participation communities region. To include diversity perspectives, systemically address discrimination bias rooted socioeconomic class system, anti-Blackness, anti-Brownness, anti-Indigeneity, misogyny, homophobia, tokenism, ableism. Instead seeking individual excellence rewarding top-down institutions North South can collective leadership. In adopting these approaches, we, ornithologists, community researchers across academia building paradigms reconcile relationships transform science.

Small intra-tropical long-distance migratory birds track rainy seasons across hemispheres

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2039)

Published: Jan. 1, 2025

The main features of long-distance migration are derived from landbirds breeding in the Northern Hemisphere. Little is known about within tropics, presumably because tropical species typically move opportunistically and over shorter distances. However, such generalizations weakened by a lack solid data on spatial, temporal behavioural patterns intra-tropical migrations. To start filling research gap, we provide comprehensive for small-sized intra-African migrants, woodland kingfishers. We inferred stationary locations, timing, flight behaviour wind experienced en route multi-sensor loggers recording atmospheric pressure, light acceleration. After South Africa, all tagged individuals migrated 4000 km to Sudan, spending their non-breeding period 100 each other. Thereby, kingfishers tracked climatic niche, using two rainy seasons open across Equator. Migratory flights were strictly nocturnal, reaching 2890 m.a.s.l. Flights unusually short, but lengthened when crossing rainforests, adjustment similar barrier-crossing along well-described flyways. These results suggest that displays surprisingly other Pending confirmation species, migrations might be more extensive less flexible than assumed, underlining importance further guiding conservation efforts.

Migration distance is a fundamental axis of the slow-fast continuum of life history in boreal birds

Ornithology, Journal Year: 2021, Volume and Issue: 138(4)

Published: July 7, 2021

Abstract Seasonal migration is intrinsically connected to the balance of survival and reproduction, but whether migratory behavior influences species’ position on slow-fast continuum life history poorly understood. We found that boreal-breeding birds migrate long distances exhibit higher annual adult lower reproductive investment relative co-distributed boreal species shorter winter closer their breeding grounds. Our study uses “vital rates” data output survivorship compiled from literature for a assemblage 45 mostly passerine birds. These breed sympatrically in North American forests diversity environments northern winter. After controlling body size phylogeny, distance apparent are positively related across species. Both correlated with wintering warmer, wetter, greener. At same time, longer migrations associated reduced time spent grounds, clutch sizes, fecundity (clutch × maximum number broods per year). Although seasonal often high mortality, our results suggest long-distance imposes selection pressures both confer demand rates. That is, owing cost migration, this strategy can only persist if balanced by survival. supports idea evolves promote environments. In birds, evolution longest yields highest survival, at an inherent fecundity. therefore reveal as fundamental axis predicts, inextricable from, reproduction.

Published: Jan. 1, 2024

Birds exhibit a high degree of migratory diversity, which is influenced by various ecological factors and life history strategies. Conducting studies on tropical bird migration, research scarce, comparing it with temperate birds can enhance our understanding migration behaviour its underlying mechanisms. In this study, we explored the breeding population Barn Swallow (Hirundo rustica) in Zhanjiang, southern China, region located northern tropics, using light-level geolocators. From 2021 to 2023, deployed geolocators 92 swallows retrieved successfully from 23 individuals. These all exhibited behaviour, wintering islands Southeast Asia. They displayed sex differences their locations. All males concentrated Borneo, while females primarily chose Borneo but also dispersed Philippines, South China Sea, Vietnam for wintering. The studied swallow adopted seasonal pattern "indirect autumn, direct spring", bypassing barrier Sea autumn tending directly cross spring migration. Moreover, distance duration was significantly longer than those Compared Swallows, Zhanjiang adopts "intra-tropical migration" initiates earlier. formation may be limited physiological factors.

Unveiling the migratory patterns of scarlet flycatchers using citizen science databases

Ornithology Research, Journal Year: 2025, Volume and Issue: 33(1)

Published: Jan. 17, 2025

Abstract The migratory patterns of many Neotropical bird species remain largely unknown. Numerous logistic challenges prevent such studies, from research costs, often prohibitively expensive to institutions, equipment weight limitations. Therefore, it is paramount explore new possibilities in the field as abundant records citizen science platforms. In this study, we investigated spatial and temporal scarlet flycatcher Pyrocephalus rubinus using two platforms: eBird WikiAves, which provided 40,837 species. Our findings indicated that flycatchers arrive at wintering grounds central-western Brazil, central-eastern Bolivia, eastern Peru around May June. We also found breeding central Argentina, southern Uruguay between August October, where stays months thereafter (November, December, January). year-round northern Argentina Paraguay deserve further studies. Understanding imperative for predicting population dynamics climate influence on biology these face a rapidly changing world.

PLoS ONE, Journal Year: 2024, Volume and Issue: 19(4), P. e0299954 - e0299954

Published: April 18, 2024

For migratory birds, events happening during any period of their annual cycle can have strong carry-over effects on the subsequent periods. The strength between non-breeding and breeding grounds be shaped by degree connectivity: whether or not individuals that breed together also migrate and/or spend season together. We assessed White-crested Elaenia (Elaenia albiceps chilensis), longest-distance migrant flycatcher within South America, which breeds in Patagonia spends as far north Amazonia. Using light-level geolocators, we tracked movements elaenias southern compared it with northern (1,365 km north) using Movebank Repository data. found successively used two separate regions while Brazilian grounds, already for site. Elaenias both showed high spread overlap among from sites, similar migration phenology, all suggests weak connectivity this species. Elucidating species, particular emphasis females juveniles, still requires further research across a wide expanse America. This information will critical to understanding possibly predicting species' response climate change rapid land-use changes.
