True’s Beaked <strong>Whale</strong> (Mesoplodon mirus)<br />
Míol Mór Socach Breá<br />
Little is known about the distribution or behaviour of True’s<br />
beaked whales off the <strong>Irish</strong> coast as they have never been<br />
observed alive in <strong>Irish</strong> waters. Between 1899 <strong>and</strong> 2009, ten<br />
str<strong>and</strong>ing records have been documented, all of which have<br />
been of single animals. Only one live str<strong>and</strong>ing has been<br />
recorded which was in Owenahincha, Co Cork, in 1997. The<br />
only other str<strong>and</strong>ing record received for this species since<br />
1997 was of a badly decomposed male found at Str<strong>and</strong>hill,<br />
Co Sligo, on 20 March 2009. Str<strong>and</strong>ings do not appear to be<br />
seasonal, with records in January (1), February (1), March (1),<br />
April (1), June (2), July (1), October (1) <strong>and</strong> November (1) with<br />
one record undated.<br />
