Management and Conservation

Onaga Ambiental colaborates with projects concerning the management and conservation of endangered species.

Most recently we have been involved with:

Project to conserve the Lesser Grey Shrike in Spain

Project to reintroduce the Black Vulture to the Catalonian Pyrenees

Supplementary Feeding Points for scavenging birds in the Pyrenees

Project to conserve the Lesser Grey Shrike in Spain

Since 2007 Onaga has undertaken conservation tasks in situ in order to protect the Lesser Grey Shrike (Lanius minor) for the association Trenca and the Catalan Government.

This migratory shrike is one of four which breed in the Iberian Peninsula. It is presently critically endangered with just one nesting pair in 2013.

Thanks to the conservation project it has been bred in captivity and 109 have been released back into the wild. Six have returned and one of them has hatched 5 chicks for the first time in history

Project to reintroduce the Black Vulture to the Catalonian Pyrenees

Ever since it began in 2007, the members of Onaga have worked on the project to reintroduce the Black Vulture to the foothills of the Catalan Pyrenees with the collaboration of Trenca and hand in hand with GREFA.

Five years into the project we consider that the initial objectives have been realized:

  • To recover a species that had recently become extinct
  • To consolidate the connection between the French and the Iberian Black Vulture populations
  • To create the foundation for development of eco-tourism in the associated with the reintroduction regions; with the presence of the 4 European vulture species breeding in the same natural space

In 2013 five couples have started playing and 3 chickens have flown successfully. The number of vultures exogenous to the project (provinientes of Iberian and French colonies) has continued to increase, with a record of 11 Iberian copies in one day.

Reintroduction of the Black Vulture in the Pyrenees: YEAR 2012

Supplementary Feeding Points (SFP) for scavenging birds in the Pyrenees

The members of Onaga have always been involved in the co-ordination of the SFP project from the Trenca association. From when the project was drawn up to the transport of the food, from the search for suitable locations to the negotiations with locals (town halls and private landowners), right down to signing of agreements of the custody of the land.

The object of the exercise is to offset the lack of food that these birds feed off due to the down turn in open grazing and it being illegal to leave carcases in the open since the mad cow crisis in 2000.

The feeding points (SFP) are also a vital support for the reintroduction of the Black Vulture to the Pyrenees, providing the birds with a reliable food source reducing the risk of poisoning and the danger of straying into unsafe territory.

Up to the present date the 3 feeding stations receive regular visits from the 4 species of vultures:

  • Lammergeyer
  • Egyptian Vulture
  • Black Vulture
  • Griffon Vulture

As well as: Red Kite y Black Kite, crows, and occasionally the Golden Eagle.
