Unusual raptor nests around the world

[EN]: From surveys in many countries, we report raptors using unusual nesting materials (e.g., paper money, rags, metal, antlers, and large bones) and unusual nesting situations. For example, we documented nests of Steppe Eagles [Aquila nipalensis] and Upland Buzzards [Buteo hemilasius] on the groun...

Description
Summary:[EN]: From surveys in many countries, we report raptors using unusual nesting materials (e.g., paper money, rags, metal, antlers, and large bones) and unusual nesting situations. For example, we documented nests of Steppe Eagles [Aquila nipalensis] and Upland Buzzards [Buteo hemilasius] on the ground beside well-traveled roads, Saker Falcon [Falco cherrug] eyries in attics and a cistern, and Osprey [Pandion haliaetus] nests on the masts of boats and on a suspended automobile. Other records include a Golden Eagle [A. chrysaetos] nest 7.0 m in height, believed to be the tallest nest ever described, and, for the same species, we report nesting in rudimentary nests. Some nest sites are within a few meters of known predators or competitors. These unusual observations may be important in revealing the plasticity of a species' behavioral repertoire. [ES]: A partir de censos realizados en muchos países, documentamos el uso de materiales inusuales (e.g., billetes, trapos, metal, cuernos de ciervos y huesos grandes) para la construcción de los nidos y de situaciones de anidación inusuales por parte de las rapaces. Por ejemplo, documentamos nidos de Aquila nipalensis y de Buteo hemilasius en el suelo al lado de caminos muy transitados, de Falco cherrug en áticos y en una cisterna, y de Pandion haliaetus en los mástiles de barcos y en un automóvil suspendido. Otros registros incluyen nidos de A. chrysaetos a 7.0 m de altura, lo que se cree es el registro más alto descrito hasta la fecha y, para la misma especie, documentamos anidación en nidos rudimentarios. Algunos sitios de anidación están a pocos metros de depredadores o competidores conocidos. Estas observaciones inusuales pueden ser importantes en revelar la plasticidad del repertorio de comportamientos de la especie.
