Resumo: Are quartzite scree slopes used by birds to promote sound transmission in the Mediterranean forest? Birds generate vocalisations (songs and calls) to communicate. Acoustic communication may be hindered by habitat features so birds can use several strategies to favour sound transmission. Sound transmission depends on the acoustic properties of their habitats. Scree slopes, also known as 'pedrizas', are frequent in the Mediterranean forests of south and central western Spain. As the acoustic properties of these rocky grounds might favour sound transmission, we propose that birds might actively use 'pedrizas' to increase sound transmission. We assessed the following prediction of the hypothesis: the number of vocalisations recorded should be higher near the 'pedrizas' than in forest areas far away from 'pedrizas'. Using portable recorders in the Mediterranean forest of Monfragüe National Park, we found that the number of recorded vocalisations was higher near the 'pedrizas'. As this result was not due to differences in species richness, we consider it supports the prediction of the hypothesis. This is new evidence that birds might use a natural element within their habitat to increase sound transmission.

Las aves generan vocalizaciones (melodías y llamadas) para comunicarse. Como la comunicación acústica puede verse obstaculizada por ciertas características del hábitat, es posible que las aves se valgan de diferentes estrategias para favorecer la transmisión del sonido. La transmisión del sonido depende de las propiedades acústicas del hábitat. Las pedrizas son frecuentes en los bosques mediterráneos del oeste meridional y central de España. Las propiedades acústicas de este terreno pedregoso podrían favorecer la transmisión del sonido, de forma que la hipótesis que se formula es que las aves podrían utilizar las pedrizas para aumentar la transmisión del sonido. Se evaluó la siguiente predicción de la hipótesis: el número de vocalizaciones grabadas debería ser superior cerca de las pedrizas que en zonas forestales alejadas. En este estudio se utilizaron grabadoras portátiles en el bosque mediterráneo del Parque Nacional de Monfragüe, y el número de vocalizaciones grabadas fue superior cerca de las pedrizas. Este resultado no se debió a diferencias en la riqueza de especies, de manera que respalda la predicción de la hipótesis. Este es un nuevo indicio de que las aves podrían utilizar un elemento natural de su hábitat para aumentar la transmisión del sonido.2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/101211http://hdl.handle.net/10316/101211https://doi.org/10.32800/abc.2021.44.0175eng2014928X1578665XPérez–González, J.Rey Gozalo, G.Montes González, D.Hidalgo de Trucios, S.
