# Tagging and tracking the Critically Endangered Balearic Shearwater

The [Royal Naval Birdwatching Society](http://www.rnbws.org.uk/) has recently published [Volume 62](http://www.rnbws.org.uk/394/)of its annual journal *Sea Swallow* for 2013.  It carries an article describing recent research undertaken on the [ACAP-listed](http://www.acap.aq/index.php/en/resources/acap-species2) and [Critically Endangered](http://www.birdlife.org/datazone/speciesfactsheet.php?id=30026) Balearic Shearwater *Puffinus mauretanicus* at its breeding sites on the Balearic Islands of Mallorca and Menorca.

 Russell Wynn ([National Oceanography Centre](http://noc.ac.uk/), Southampton, UK) and British and Mallorcan colleagues continued to deploy GLS and GPS trackers and time-depth recorders to birds for the third year.  [Click here](http://www.acap.aq/index.php/en/news/latest-news/1491-project-shearwater-continues-to-study-the-acap-listed-balearic-shearwater-at-its-breeding-sites-and-at-sea) for more details of this year’s and previous year’s field work and [here](http://www.acap.aq/index.php/en/news/news-archive/57-2012-news-archive/143-leaving-the-med-behind-balearic-shearwaters-prefer-to-holiday-along-the-french-and-portuguese-atlantic-coasts) to access an earlier publication by the research group on results from the first year of at-sea tracking.
