Emergency conservation work pays off: Zino’s Petrel bounces back!

Zino’s Petrel was Europe’s rarest seabird even before a ravaging wild fire hit the heart of Madeira’s central massif, where this globally endangered bird breeds.

The fire, in August 2010, had dire consequences: 25 young and 3 adults were found burnt to death, and of the 13 young birds found alive, only one survived to fledge that year – the others were predated in their now obvious nests on the barren mountain ledges.

Suddenly, the species’ population – which had been increasing steadily in recent years, thanks to efforts by the Natural Park of Madeira (PNM) – was jeopardized.

The situation was grave indeed – the fire not only led to a near-complete breeding failure in 2010, but also exacerbated soil erosion, causing several nesting burrows to collapse.

As soon as the smouldering cinders permitted it, PNM developed an action plan to mitigate the consequences of this natural disaster. A team of conservation wardens was deployed to place anti-erosion coconut mesh on the breeding ledges to protect the soil in some of the most critical places.

Then, with financial and logistical support from SPEA/BirdLife in Portugal, the RSPB/BirdLife in the UK and BirdLife International, about 100 natural nests were restored, while 60 new artificial nests were built. A protective cordon was also built around the known breeding areas, with cat traps and bait boxes.

Forest fires in Madeira put future of Europe's rarest seabird under threat

Europe's rarest seabird, the Zino's Petrel, found only in Madeira, has suffered potentially devastating losses from a forest fire which struck the birds' breeding area on the Atlantic island.


The fire on Madeira's central mountain massif killed 25 chicks – 65 per cent of this year's young birds – with only 13 fledglings found alive in their underground burrows. These remaining few will have to contend with the effects of severe soil erosion which the fire has caused. Three adult birds also died.

One of the rarest birds in the world, Pterodroma Madeira was once believed to be extinct and was only rediscovered in 1969. Since then its numbers have been down to a few tens of pairs, but intense conservation action in recent decades has seen its population grow and almost 80 pairs now nest on the island. In recent weeks, forest fires ravaged parts of Madeira, and eventually hit the heart of the central massif, whose mountain ledges support a number of endemic plants and animals (some of the wild flowers surviving because they are inaccessible to goats).

The petrels breed on ledges 5,250ft up where there needs to be enough earth for the birds to burrow and make their nests. They face numerous threats, ranging from predators such as rats and cats to habitat degradation and human disturbance: in 1991 the remains of 10 Zino's Petrels were found on one ledge, all of them apparently killed by cats. Shepherds used to collect juvenile birds for food, and egg-collectors have raided nest burrows in the past.

Late last year another threat appeared in the shape of a Nato radar station being built on the summit of Pico do Areeiro, the mountain in the heart of the breeding area. Authorities insists it is necessary for military purposes, but it is feared the building work and the station will affect the birds.

A conservation effort in the breeding area has hitherto protected the birds. "Losing 65 per cent of this year's potential young is a blow to Zino's Petrel," said Ana Isabel Fagundes, of Portugal's national ornithological society, SPEA.

Conservation teams have reinforced nests with surviving birds, and removed the bodies of the dead ones. "Burnt bushes and trees have been removed to avoid the risk of adult birds colliding with them on their nocturnal visits to feed the chicks," said Paulo Oliveira, director of the Natural Park of Madeira.
