A bird of prey that nests on the ground

Visit Cabeceiras includes the tartaranhão-hunter in the fauna of Cabreira. SPEA describes Circus pygargus as a summer bird, which returns to Portugal in the spring to nest. It prefers open spaces, mainly insects hunting and nests in the soil, among high vegetation. The reference covers the mountains; it does not identify nests or sighting points in the municipality.

The annual cycle connects continents. The LIFE SOS Pygargus project describes the winter in Africa and the return to the Iberian Peninsula in the spring, for reproduction, with permanence in breeding territories until September. This general calendar does not mark exact dates of arrival and departure to the Cabreira.

The long and narrow wings and tail are part of the portrait presented by LPN. Its mini-guide includes low mountain woods between habitats and refers to nests in high fields or landings. The menu is also broader than insects: it can include birds, small mammals and lizards. A prey of open spaces thus depends on both prey and vegetation suitable for nesting on the ground.
