Temporal patterns of cooing activity of the European turtle dove Streptotelia turtur: optimizing monitoring schemes based on abundance indice

Surveys based on abundance indices may still be the most cost-efficient method for monitoring programmes that aim to be extensive in time or space, but it is important to take into account differences in activity patterns when combining data collected at different times or from different areas.

description Surveys based on abundance indices may still be the most cost-efficient method for monitoring programmes that aim to be extensive in time or space, but it is important to take into account differences in activity patterns when combining data collected at different times or from different areas. The European Turtle-dove Streptopelia turtur is a migratory game species that has declined in recent decades and for which identifying efficient and easy-to-apply monitoring schemes to assess changes in abundance is critical for adaptive management. We describe variation in cooing activity to help optimising Turtle Dove abundance monitoring schemes based on point-counts of cooing males. Cooing activity (number of minutes during a ten-minute sampling period when each Turtle Dove was cooing) declined markedly and linearly throughout the morning; in addition, it increased slightly from May to late June, and declined abruptly in the second half of July. The number of different turtle doves detected per ten-minute period significantly declined with time since dawn and was markedly lower after mid-July. Predicted abundance per observation point at dawn on 25 June (from a GLM per region including time and a quadratic relationship with date), correlated tightly (r = 0.95) with the average number of turtle doves detected at each point over multiple visits during the breeding season. Correlation of the latter with the number of birds observed in a single visit during the breeding period was weaker (0.68 ± 0.02). Estimated abundance per point was higher the longer the monitoring bout duration, but five-minute periods allowed detecting c. 80% of birds detected during ten-minute periods. To optimize Turtle Dove abundance monitoring schemes based on abundance indices, we suggest implementing fiveminute samplings from mid-May to mid-July during the first three hours after dawn, and transforming the observed values into predicted values considering the date and time at which surveys were made, to obtain comparable results across observation points and years.

La tórtola europea Streptopelia turtur es una especie cinegética migratoria que ha disminuido de forma importante en las últimas décadas, y para la cual es fundamental identificar sistemas de monitorización eficientes y fáciles de implementar para evaluar cambios de abundancia para un manejo adaptativo. En este trabajo describimos la variación en la actividad de canto para optimizar los programas de monitorización de abundancia de tórtolas basados en puntos de escucha de machos cantores. La actividad de canto (el número de minutos durante un período de muestreo de 10 minutos en los que cada tórtola se escuchó cantando al menos una vez) disminuyó marcada y linealmente a lo largo de la mañana; además, aumentó levemente desde mayo a fines de junio, disminuyendo abruptamente en la segunda quincena de julio. El número de tórtolas detectadas por punto en un período de 10 minutos disminuyó significativamente desde el amanecer y fue notablemente más bajo después de mediados de julio. La abundancia predicha por punto de observación al amanecer del 25 de junio (a partir de un GLM por región incluyendo una relación lineal con la hora y una relación cuadrática con la fecha), se correlacionó estrechamente (r = 0,95) con el número promedio de tórtolas detectadas en cada punto durante múltiples visitas durante la temporada de reproducción. La correlación de esta última variable con el número de aves observadas en una sola visita durante el período de cría fue más débil (0,68 ± 0,02). La abundancia estimada por punto fue mayorcuanto mayor fue la duración del tiempo de muestreo por punto, aunque períodos de 5 minutos permitieron detectar ca. 80% de las aves detectadas en 10 minutos. Para optimizar los programas demonitorización de abundancia de tórtolas basados en índices de abundancia, sugerimos implementar muestreos de 5 min desde mediados de mayo hasta mediados de julio en las primeras tres horas dela mañana, y ajustar los valores observados transformándolos en valores predichos considerando el día y la hora en que se realizaron las encuestas, para obtener resultados comparables entre puntosde observación y años.SEO BirdLIFe202520252023info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://hdl.handle.net/10578/43197reponame:RUIdeRA.
