# Recent Spanish research on the Critically Endangered Balearic Shearwater: a potential candidate for ACAP listing  UPDATED

An International  Action Plan compiled by José Manuel Arcos and commissioned by the European Commission is now available for the Balearic Shearwater ([click here](http://ec.europa.eu/environment/nature/conservation/wildbirds/action_plans/docs/puffinus_puffinus_mauretanicus.pdf)).

  ************

 At the Fifth Meeting of ACAP's Scientific Committee held in Argentina in 2010 an information paper ([AC5 Inf5](https://acap.aq/english/english/advisory-committee/ac5/ac5-information-papers)) submitted by the Secretariat gave a brief review of the conservation status of shearwaters of the genera *Calonectris* and *Puffinus*.  The paper suggested that nine species (out of a total of 22) might be considered for listing within the Agreement.

 The [Critically Endangered](http://www.birdlife.org/datazone/speciesfactsheet.php?id=30026)  Balearic Shearwater *Puffinus mauretanicus*, endemic to the Spanish Mediterranean, is one of these candidate species.

 Dr Maite Louzao, who completed her doctorate on the species in 2006, has been co-authoring papers on the Balearic Shearwater over the last several years.  Her thesis and recent publications on shearwaters of the Mediterranean are listed here.
