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

For such purpose, it provides researchers with accomodation, various facilities and technical/logistical support. It also runs monitoring programs to assess the status and trends of biodiversity, provides online access to all the information gathered by these monitoring programs and delivers ICT service management 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.

Start a project

If you plan to do research in Doñana, you must bear in mind that your project must be approved by the Research Access Commission of the Doñana Participation Council. The ICTS-RBD provides assistance throughout the procedure. Read more

Request access, accommodation and/or technical and logistic support

Once your research project has been approved by ICTS-RBD, you can request access and accomodation in the Biological Reserve using this online form and/or logistic or technical support using this online form . Do not forget to read carefully the facilities’ use rules. Read more

Request biodiversity data

You can visualize ICTS-RBD’s biodiversity monitoring data at the Data Infrastructure and consult essential ecosystem indicators derived from them at the Global Change Observatory. Raw data are offered free of charge to competitive research projects, subject to the following terms and conditions of use included in this data-request form.
