Abstract Animal tolerance towards humans can be a key factor facilitating wildlife–human coexistence, yet traits predicting its direction and magnitude across tropical animals are poorly known. Using 10,249 observations for 842 bird species inhabiting open ecosystems in Africa, South America, Australia, we find that avian was lower (i.e., escape distance longer) rural rather than urban populations exposed to human disturbance (measured as footprint index). In addition, larger with clutches...
Escape behaviour in response to perceived predators can be employed as a guide when designating protected areas around sensitive bird species minimise the impact of human disturbance. A key measure escape is flight-initiation distance (FID), at which prey animal initiates its approached by potential predator. We tested predictions optimal theory determining factors that influence FID Nigerian reserved area and surrounding habitats, so utility managing disturbance on birds, for first time...
Despite many bird species migrating regularly within the African continent, in response to rainfall and breeding opportunities, documented evidence of spatiotemporal patterns such movements is scarce. We use satellite telemetry document year round movement an intra‐African migrant savannah zone sub‐Saharan Africa, cuckoo. After central Nigeria, birds migrated more forested sites Adamawa region Cameroon (n = 2) western Central Republic 1). Departure from ground coincided with deteriorating...
AbstractThe scale of movement associated with the migration many intra-African bird species is still poorly known even increasing availability tracking devices. In this study, we tracked movements Black Coucals Centropus grillii breeding in Nigeria from late July using satellite telemetry. Individuals remained on site for several months; two individuals transmitted after October and these moved shorter distances (< 100 km) away early December. One was a full year, moving to 175 km south...
Abstract Urbanisation and its associated habitat loss fragmentation are considered a major threat to wildlife. In this study, we assessed the predictors of bird species abundance, richness composition within 70 cells 500 m by spread across five urban areas constituting Ibadan metropolis. A total 4167 individuals 55 belonging 30 families were recorded. We report that Laughing dove Streptopelia senegalensis , Speckled pigeon Columba guinea Yellow‐billed kite Milvus aegyptius contributed...
Almost no systematic monitoring of bird population trends occurs in West Africa, despite rapid human increase, habitat change, and climate making conservation planning problematic. We monitored using constant-effort mist netting, a newly protected area (Amurum Forest Reserve) on the outskirts Jos, central Nigeria, from 2002 to 2019. modelled 18-year changes 10 Palearctic migrant 41 common resident species related this any annual environmental site quality NDVI rainfall data. The populations...
Current knowledge of the migration Common Sandpiper Actitis hypoleucos is still limited. The species has been ringed at Ottenby Bird Observatory, southeast Sweden, since 1947, allowing for analyses long-term and seasonal trends. We analysed trapping data 1,942 adults 3,290 juveniles with respect to patterns in phenology, morphometrics, fuel load. used loads estimate potential flight ranges. number adult birds trapped increased significantly over years, whereas declined. Median passage date...
Information regarding the spatial behaviour of migratory bird species on their wintering ground is important in understanding factors that can influence breeding success and population size. The Garden Warbler Sylvia borin a has been well studied West Africa. However, information its during non-breeding season sub-Saharan Africa still limited. Consequently, we investigated 50% 95% kernel density home-range size overlap as food choice 10 radio-tracked Warblers at Amurum, central Nigeria...
The Garden Warbler breeds in the Palaearctic and migrates to sub-Saharan Africa for non-breeding season. We studied its passage, body mass moult at Obudu Plateau southeast Nigeria October–December 2005 December 2007–January 2008. In Nigeria, Warblers Guinea savanna have been shown increase October–November, preparing migration wintering sites further south. They begin arrive from mid-October numbers gradually with time; median date of passage was 3 December. This influx is clearly different...
Long-term ringing data are useful for understanding population trends and migration strategies adopted by migratory bird species during migration. To investigate the patterns in demography, phenology of stopover behaviour Wood Sandpipers Tringa glareola trapped on autumn at Ottenby, southeast Sweden, 1947 − 2011, we analysed 65 years to describe age-specific annual trappings, morphometrics phenology, as well fuel deposition rates duration from recapture data. We also direction recovery Over...
The vegetation in urban green spaces is often managed by means of machines and/or pesticides including herbicides for aesthetics without regard to the potential consequences on arthropods, particularly insect abundance, and animals, especially birds, that feed insects other arthropods. Using University Cape Coast campus cattle egrets (Bubulcus ibis) there as a test case, we investigated influence arthropod abundance structure foraging success egrets. To achieve this, measured efficiency (FE)...
Though agriculture has been linked to the decline in bird populations due associated changes vegetation structure and composition, its potential sustain birds explored over time. A sustainable agricultural landscape should be one that capacity support species all year. To this end, we investigated factors influencing pre- post-harvest farm conditions on abundance, richness, feeding guilds three different crop fields Jos-East North, central Nigeria. We used line transects survey variables...
The interactions of birds with trees facilitate the provision ecosystem services that are crucial for maintaining ecosystems. Knowledge these can be beneficial to conservation actions. study assessed bird-tree interaction network and encounter rates within Akoka campus University Lagos. Focal observations avian visits were made 15 minutes on a total 50 randomly selected spaced 200 m apart. Each tree was visited repeatedly from February June 2022. A 14 bird species belonging 13 families...
The white-bellied pangolins (Phataginus tricuspis) harbour ecto- and endo-parasites. In this study we compared the bioaccumulation potentials of metadavinae cestode stongylondes nematode parasites for trace metals in intestine, lipid profile liver infected uninfected P. tricuspis sampled from Epe Local Government Area, Lagos State, Nigeria. Trace metal concentrations were determined pangolin its intestinal using a Flame Atomic Absorption Spectrometer. Total cholesterol levels enzymatic...

This study investigated factors influencing bushmeat perception disease among vendors buyers commodity at Oluwo Market, Epe, Lagos, Nigeria. Data was collected using 150 structured interviewer-administered questionnaires through KoboCollect survey tool between February October 2022. Results revealed that top three sought after were...

Introduction The rural-urban gradient serves as a valuable context for investigating the impact of urbanization on biodiversity. While previous studies have demonstrated shifts in bird communities along this gradient, our understanding specific impacts individual urban components such man-made physical structures and anthropogenic noise remains limited, more so, Afro-tropical environments. Method Employing point count method, we recorded birds also determined levels structures, across...
Seed dispersal is fundamental to the resilience of plant communities and birds are important seed dispersers, contributing maintenance restoration community structures. In this study, we investigated contributions bird species in a woodland savanna Jos, Nigeria. dry season 2022, observed consuming fruits on 104 individual plants belonging 26 species. Five hundred six (506) 19 12 families were from focal plants. Bird trapping was conducted collect intact seeds fecal samples examine...
Trapping and ringing near ecological barriers can provide useful information about the migration strategies of bird species. In this paper we analyzed data Garden Warbler, collected within period 1950–2008 at Ottenby Bird Observatory, south-eastern Sweden, describe patterns in phenology, morphometrics fuel load. A total 4,351 individuals aged as either adults or juveniles were ringed during (yearly averages 7.3 83.1 juveniles) addition to 1,514 birds un-known age. Both age-specific combined...
