Research into bird habitat selection can unveil the impact of specific characteristics on survival. However, empirical information environmental factor preferences and differences within yew ecological garden for birds is still lacking. This study was conducted in a located southern experimental area Meihua Mountain National Nature Reserve, Fujian Province, China. We selected three commonly occurring species analysis to discern factors influencing interspecific factors. Canopy density coverage were identified as dominant Red-billed Blue Magpie (Urocissa erythrorhyncha), Black Bulbul (Hypsipetes leucocephalus), Orange-bellied Leafbird (Chloropsis hardwickii). The height perching trees, average tree height, diameter at breast all important determinants Bulbul. These consistent with logistic regression results. Both one-way ANOVA stepwise discriminant revealed significant among species. Our results provide insights avian patchy habitats, which be used guideline future conservation management.

Zusammenfassung Im Gegensatz zum Menschen ist der Ort Lautbildung bei Vögeln nicht Kehlkopf, sondern sog. „Stimmkopf“ (wissenschaftliche Name „Syrinx“). Bei einigen Arten Syrinx an Bifurkation Trachea in die beiden Hauptbronchien (trachealer Stimmkopf), anderen den (bronchialer Stimmkopf) lokalisiert. Inspiration strömt ein Teil Luft Lunge, Singen benötigte Lunge benachbarten Luftsäcke. Während Exspiration verlässt Luftsäcke, durch Syrinx, wo dann Gesang entsteht. Wenn Vögel gleichzeitig zweistimmig singen, werden einzelne Sequenzen simultan im rechten und linken Anteil gebildet. Die Gesangsanalyse erfolgt mittels Spektrogrammen (sog. Sonagrammen), zeitlichen Verlauf des Frequenzspektrums Vogelgesangs grafisch darstellen. Der besteht aus einer oder mehreren Strophen, ihrerseits variablen bzw. konstanten Abfolge von Motiven Silben aufgebaut sind. Einige Singvögel verfügen über enormes Silben- Strophenrepertoire (max. bis zu 7000 Strophen/Tag). meisten Vogelarten existieren neben dem auch deutlich einfachere Bettel-, Kontakt-, Droh-, Flug-, Alarm- Kopulationsrufe. männlichen hat vorwiegend zwei Funktionen: 1. Mithilfe Gesangs wird um eine mögliche Partnerin geworben. Den Weibchen liefert wichtige Informationen Leistungsfähigkeit Gesundheitszustand Bewerbers. 2. dient Revierverteidigung. ca. 40 % Singvogelarten singen Weibchen. Pärchen mancher Singvogelart perfekt synchronisiert. Eine ganze Reihe Singvögeln imitiert sowohl Stimmen anderer als Umgebungsgeräusche viele besitzen regionale Dialekte. Gesangsentwicklung hängt genetischen weiteren Faktoren, wie z. B. Umwelt, Stoffwechsel hormonellem Einfluss, ab. Sie verläuft schrittweise beinhaltet initial relativ primitive „subsongs“), führt komplexere Zwischenformen („plastic songs“) vollendeten Gesangsmuster („full songs“). Jungvögel lernen ihrer Art bereits einem Zeitpunkt, sie selbst noch gar oft Alter 10–50 Tagen Prägung älteren Artgenossen, gewöhnlich Vätern. In Netzwerk sensomotorischen Neuronen Vorderhorn entwickelt sich auf Basis Schablone Erwachsenengesangs. Für das Sprachlernen bieten Singvögel, insbesondere Zebrafink, derzeit beste Modell bzgl. neuronaler Mechanismen Sprachlernens. orchestriert „High Vocal Center“ (HVC) alle für relevanten Hirnregionen, wobei neuronale Kontrolle sensitiv Geschlechtshormone ist.

This study examined bird composition, abundance and diversity in Shere Hills Reserve, Jos Plateau, North Central Nigeria. The region, characterized by a savanna ecosystem interspersed with rocky outcrops gallery forests, has mean annual rainfall of 1,260 mm temperature range 19.4°C to 34.5°C. Bird surveys were conducted across 65 points using the point count method, stratified habitat type: forest, savanna, outcrops. Observations made daily between 6:30 a.m. 10:30 a.m., species identified ‘Birds Western Africa’ field guide. A total 6,427 birds representing 142 53 families recorded. Gallery forests exhibited highest composition (121 species), followed savannas (111 (108 species). Notable included Blue-breasted Kingfisher Chestnut-backed Sparrow Lark savannas, Rock-loving Cisticola habitats. Despite these differences did not vary significantly habitats (F2, 585 = 0.59, p 0.56). (1.92 ± 0.03) forest (1.91 had slightly higher compared (1.87 0.03). findings underscore importance heterogeneity supporting avian biodiversity contributing richness diversity.

Introduction Urbanization, characterized by the rapid expansion of human settlements and development, greatly impacts biodiversity, especially where developments are not guided proper environmental consideration. Methods We used data collected through citizen science projects under African Bird Atlas Project, based on standardized protocols to gather bird occurrence data. Species’ ecological traits, related foraging behavior, habitat speciality, body mass, were analyzed assess functional richness diversity (FD) represented Rao’s quadratic entropy. Geospatial data, including Global Human Settlement Layer Modification Index (HMI), along with probability urban up 2030, integrated examine impact urbanization using Bayesian models. Results Our findings reveal a marked decline in taxonomic richness, diversity, associated increasing modification, similar pattern observed gradient from mostly uninhabited areas cities. However, FD increased The relationship between HMI was nonlinear, showing an initial negative trend that became positive as increased. This suggests transition communities, generalist species thrive environments, potentially replacing specialized leading redundancy. Discussion Despite complex relationships observed, has predominantly Afrotropical communities. avian important implications for ecosystem functions services, crucial biodiversity well-being. research provides valuable insights into emphasizes importance preserving natural habitats amidst growing landscapes.
