Recognition of bird species with birdsong records using machine learning methods

PLoS ONE, Journal Year: 2024, Volume and Issue: 19(2), P. e0297988 - e0297988

Published: Feb. 23, 2024

The recognition of bird species through the analysis their vocalizations is a crucial aspect wildlife conservation and biodiversity monitoring. In this study, acoustic features Certhia americana , brachydactyla familiaris were calculated including Acoustic complexity index (ACI), diversity (ADI), evenness (AEI), Bioacoustic (BI), Median amplitude envelop (MA), Normalized Difference Soundscape Index (NDSI). Three machine learning models, Random Forest (RF), Support Vector Machine (SVM), Extreme Gradient Boosting (XGBoost), constructed. results showed that XGBoost model had best performance among three with highest accuracy (0.8365) AUC (0.8871). This suggests an effective tool for based on indices. study provides new approach to utilizes sound data characteristics.

A fragile future for pink birds: habitat suitability models predict a high impact of climate change on the future distribution of flamingos

Emu - Austral Ornithology, Journal Year: 2023, Volume and Issue: 123(4), P. 310 - 324

Published: Sept. 20, 2023

ABSTRACTClimate change is one of the most impactful global phenomena, affecting multiple ecosystems, particularly wetlands and water bodies, as well important species that depend on these areas. Flamingos are unique distinctive live exclusively in environments highly impacted by any changes their breeding or non-breeding wetlands. To address measure direct impact future climatic could have distribution six extant flamingos, I used citizen science data variables to construct habitat suitability models. These models were predict gain loss areas short, medium, long term, under four different Shared Socioeconomic Pathways eight Global Circulation Models. The results predicted five out flamingos will experience continued over next few decades all scenarios. Dramatic expected for species. also indicate a higher climate more restrictive along borders distributions. Finally, research highlights importance combined efforts from public communities, scientists, policymakers create mitigation conservation plans avoid intensification effects prevent reduction flamingo populations.KEYWORDS: Climate changeconservationflamingoshabitat modelsPhoenicopteriformes AcknowledgmentsI am grateful Federal University Rio Grande do Sul putting facilities laboratory at my disposal.Disclosure statementNo potential conflict interest was reported author(s).Data availability statementThe support study collected freely available online databases; further details Supplementary Materials.Supplementary dataSupplemental this article can be accessed https://doi.org/10.1080/01584197.2023.2257757.Additional informationFundingThe author supported Doctoral fellowship, Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), Brazil.

Did you interfere with them? examining the environmental responsibility of birdwatchers in China

Current Issues in Tourism, Journal Year: 2023, Volume and Issue: unknown, P. 1 - 22

Published: Dec. 27, 2023

As birdwatching tourism expands rapidly and garners increased interest from tourists, it is necessary to enhance their understanding of the positive negative effects birdwatching. It similarly essential promote eco-friendly behaviour for environmental preservation more robust ecotourism. This study employs a mixed-method approach investigate factors shaping environmentally responsible conduct among tourists. The first phase was qualitative: in-depth interviews were held with members organizations delve into facets drivers tourists' behaviour. Second, quantitative performed verify influencing process these actions; key included values, knowledge, group norms, empathy nature. Results showed that biospheric values directly affected which in turn influenced Empathy nature norms each mediated relationship between knowledge behaviour; egocentric played significant moderating roles. Theoretical practical implications are discussed closing.

Are Lay People Able to Estimate Breeding Bird Diversity?

Animals, Journal Year: 2022, Volume and Issue: 12(22), P. 3095 - 3095

Published: Nov. 10, 2022

Studies about biodiversity and well-being used different approaches to assess biodiversity, e.g., scientific counts censuses or perceived estimated by the respondents. Here, we assessed whether laypeople could estimate breeding bird diversity species richness at specific places. For comparison, carried out with standard methods of professional ornithologists citizen science data from internet platform Ornitho (Germany). Lay people public (1184 respondents) were surveyed between May July 2022 40 places in southwest Germany Rottenburg/Tübingen Stuttgart following catchment river Neckar (30 per place). People asked richness/diversity this current place. show that does not correlate census nor laypeople. Laypeople have a generally good assessment richness, correlating professionals (r = 0.325, p 0.041). On average, number lies values morning afternoon census. most often afternoon; therefore, their must be done on other factors than actual birds present. This result is valuable for future studies connection well-being.

A dataset of bird distributions in zoogeographical regions of China

Biodiversity Data Journal, Journal Year: 2022, Volume and Issue: 10

Published: Dec. 29, 2022

China, the largest country in Asia, has a land area of approximately 9.6 million square kilometres. There are 1481 bird species (following taxonomy IOC World Bird List version 12.1) recorded two zoogeographical realms, seven regions and 19 subregions country. From 1955 to 2017, six authoritative monographs were published, which distribution for all China widely quoted by research papers field guides. This massive amount data could be used address many hot topics ornithology, biogeography ecology. However, rapid changes taxonomic status different schemes regionalisation these provided limits utilisation valuable data. By integrating from monographs, we presented an open-access dataset on occurrences residence types Chinese over past 60 years. The statuses determined following 12.1 based updated scheme. These provide information ecology conservation biology.

Complementando inventarios biológicos con datos abiertos a través de un método semiautomatizado

Published: Dec. 13, 2023

Introducción: Los muestreos directos constituyen la mejor manera de documentar riqueza biológica un lugar, pero pueden verse limitados por diversas circunstancias. Nos preguntamos si especies documentada en campo puede ser complementada con datos plataformas digitales biodiversidad. Objetivo: Analizar los ocurrencia disponibles Global Biodiversity Information Facility (GBIF) complementar listados creados trabajo y reportados literatura. Métodos: Comparamos aves publicaciones académicas aquellos generados usando información GBIF para las mismas áreas estudio utilizando el índice disimilitud Sorensen (βsor) sus dos componentes (recambio βsim anidamiento βsne). Resultados: reporta más (n = 26 – 232) que 14 24 consultados, menos 12 114) otros 10. La suma documentadas entre fuentes contiene hasta 246 reportadas individualmente cada una, resaltando magnitud ganarse al combinar ambas fuentes. βsor osciló 0.15 1, mostrando siempre hubo diferencias comparados. En ningún caso 0 ni βsne indicando una fuente listó ausentes otra nunca fue total. Conclusiones: registros disponible recopilada campo, ésta a su vez GBIF, lo resaltamos importancia continuar documentando través especialmente poco exploradas.
