Influence of atmospheric properties on detection of wood-warbler nocturnal flight calls

摘要: Avian migration monitoring can take on many forms; however, active nocturnal of land birds is limited to a few techniques. flight calls are currently the only method for describing migrant composition at species level. However, as this develops, more information needed understand sources variation in call detection. Additionally, studies examine how detection probabilities differ under varying atmospheric conditions. We use recordings from captive individuals explore dependence temperature and humidity. Height or distance origin had largest influence detection, while humidity also influenced detectability higher altitudes. Because varies with both conditions height, improved across time space will require correction these factors generate standardized metrics songbird migration.
