Doñana’s Singular Scientific-Technical Infrastructure (ICTS-RBD) provides access and support to carry out research at the Doñana Protected Areas.

For that purpose, it provides researchers with housing, facilities, technical and logistic support. It also runs programs for monitoring the status and trends of biodiversity, provides online access to all the information gathered by these monitoring programs, and delivers IT services and tools to facilitate the search and use of that information.

Nest decoration as a communication signal

Nest decoration as a communication signal



Avian nests are frequently concealed or camouflaged, but a number of species builds noticeable nests or use conspicuous materials for nest decoration. In territorial species decorations may serve as extended phenotypic signaling of nest-site occupancy and social status to potential intruders. The latter may benefit both signaler and receiver by minimizing the risk of aggressive interactions. Here, it was tested whether nest decorations increased nest-site visibility to conspecifics in black kites (Milvus migrans), a territorial raptor that decorates its nest with white artificial materials. Unmanned aircraft system were used to take pictures of black kite nests, with and without an experimentally placed decoration, from different altitudes and distances simulating the perspective of a flying and approaching, prospecting intruder. Decorated nests were consistently detected by human volunteers at a higher frequency and a lower latency, compared to undecorated versions of the same nests. Results confirm that nest decoration in this species acts as a signaling medium that enhances nest visibility for aerial receivers, even at large distances. This finding complements previous work on this communication system, which showed that nest decoration was a threat informing trespassing conspecifics on the social dominance, territory quality and fighting capabilities of the signaler. informacion[at]ebd.csic.es Canal et al (2016) Decoration Increases the Conspicuousness of Raptor Nests.
