Abstract

fetched live from OpenAlex

Modification of the point count survey method to include playback of songbird mobbing calls in an attempt to increase detection probabilities has met with mixed success. We compared detection probabilities for boreal forest songbirds using traditional point count methods and counts using broadcasts of the mobbing calls of Black-capped Chickadees (Poecile atricapillus) in an attempt to increase detection probability. We conducted 594 point counts during the 2010 breeding season in Newfoundland, Canada. Each point count consisted of an 8-min silent observation period followed by an 8-min broadcast of Black-capped Chickadee mobbing calls. Occupancy model results showed that response to playback broadcast varied across species, with detection probabilities higher for seven of 17 species during the silent portions of point counts and three species more likely to be detected during playback intervals. For all species, the number of visual detections increased during periods of playback and, averaged across species, individuals were >6 times more likely to be seen during the playback period than during the silent period. Differences in detection probability among observers were apparent during both silent and playback periods. We suggest that using playback of chickadee mobbing calls during point count surveys of common boreal forest songbird species may be most beneficial when visual detection is important. However, playback may also be useful for species-specific surveys during periods when birds are less likely to be vocal or for studies of less common species with chronically low detection probabilities. A combined silent and playback approach could also be useful, although observer and species differences should be accounted for if comparing data across species or studies. Efecto variable de las grabaciones de conducta de turbas en Poecile atricapillus, en la probabilidad de detectar aves en un bosque boreal Modificaciones en los conteos de puntos, para incluir grabaciones de llamadas de turbas, en el intento de incrementar las probabilidades de detección de aves han tenido resultados mixtos. Comparamos la probabilidad de detección para aves en bosques boreales, utilizando conteos de puntos tradicionales y llamadas de turbas del Carbonero Cabecinegro (Poecile atricapillus), en un intento de incrementar la probabilidad de detección de aves. Se condujeron 594 conteos de puntos durante el periodo reproductivo del 2010, en Newfoundland, Canadá. Cada punto consistió de 8 minutos de observación en silencio, seguido de 8 minutos de una grabación de la llamada de turba del Carbonero Cabecinegro. El modelo utilizado mostró que la respuesta a las grabaciones varía entre especies, con una alta probabilidad de detección de siete de 17 especies durante los periodos de silencio y de tres especies adicionales durante la exposición a grabaciones. Para todas las especies, el número de detecciones visuales incrementó durante los periodos de uso de grabaciones y el promedio entre todas estas, resultó con una probabilidad seis veces mayor de ser detectado, que durante los periodos de silencio. Entre observadores, encontramos diferencias en la probabilidad de detección, tanto durante los periodos de silencio como cuando se utilizaron grabaciones. Sugerimos el uso de grabaciones de llamadas de turba del carbonero, durante conteos de punto en bosques boreales, ya que puede ser de gran beneficio cuando la detección visual es importante. No obstante, el uso de grabaciones también pudiera ser útil para censos de especies particulares durante el periodo en que la probabilidad de escuchar sus voces sea bajo, o para estudios con especies cuya probabilidades de detectarlas sea reducido. Una combinación de conteos silenciosos y uso de grabaciones pudieran ser de utilidad, aunque se debe tomar en consideración las diferencias en la capacidad de detección que pueda haber entre observadores y especies para comparar datos entre especies y estudios.
