A European honey buzzard — Pernis apivorus — nursed back to health by the UTAD (Universidade de Trás-os-Montes e Alto Douro) Wildlife Rescue Centre was returned to the wild at Graham’s Quinta dos Malvedos on May 18th. Peter Symington, the SFE’s retired winemaker, who has been staying at the quinta with family and friends, released the female honey buzzard from one of the property’s highest vineyards at 350 metres (1,148 feet).
The Malvedos honey buzzard was taken to the University’s Veterinary Hospital in August 2016 after it had been found by members of the public, downed and injured near Miranda do Douro, a town in the north-eastern extremity of Portugal where the Douro marks the international border with Spain. The bird had been illegally shot, sustaining two fractures in one of its wings. It was operated on successfully at the veterinary hospital — which works closely with the wildlife rescue centre — and from October it began its recovery programme which consisted of several months of flying exercises in the rescue centre’s dedicated circular flight tunnel, the only one of its kind in the Iberian Peninsula. It’s unique in that it allows large birds of prey to fly continuously, thus regaining muscular strength and recovering flying proficiency in preparation for a return to nature.
Although its steady recovery was completed during the middle of winter, the rescue centre could not release the bird as it belongs to a migratory species, which flies south to sub-Saharan Africa at the end of the European Autumn in search of better feeding grounds, returning to Europe only in the spring for the mating season. As its name suggests, the honey buzzard feeds on bees and wasps and their larvae, raiding their nests. Its thick plumage, its claws covered with thick protective scales and narrow slit nostrils, protect it from attack by its preferred prey.
Dr. João Tomás, the veterinarian who accompanied the honey buzzard for release at Malvedos explained to those present that during the second week of May, approximately 8,000 honey buzzards were tracked over the Strait of Gibraltar, flying north on their return to Europe where they will mate, usually with the same partner, build nests and raise their chicks. He said that sightings of honey buzzards had already been reported in the Douro Superior and in the Trás-os-Montes and Beira Alta districts of Portugal. This was the signal that the timing was right to release ‘their’ bird.
The Symington family has supported the University’s Wildlife Rescue Centre (Centro de Recuperação de Animais Selvagens — CRAS, for short) since 2011 and several species of birds of prey have been freed at different family vineyards in the Douro over recent years. Malvedos is home to a remarkable variety of bird species, which include golden orioles, bee-eaters, turtle doves, Iberian magpies and larger birds such as black kites, which frequently nest in the wooded areas of the quinta. Just moments after the release of the honey buzzard, João Tomás identified a Bonelli’s eagle gliding effortlessly on the thermals above the vineyards.
