Leach's Petrel - 1894

Procellaria leucorrhoa

This is a little larger than the Storm-Petrel, is of a browner black, has a grey line across the edges of the wing-coverts, and a deeply forked tail, so that one of its common names is the Fork-tailed Petrel. It is not known to breed on any of our islands, but it is not very rare, as a visitor in stormy weather, and, like the Storm-Petrel, is occasionally picked up inland. The Rev. Clennell Wilkinson believes that a Petrel seen by him skimming over a pool in the Burrows in his parish of Castle Martin one day in the summer was a Fork-tailed Petrel. Mr. Dix states that it has been taken several times after severe storms in Milford Haven, and saw one in Tracy's shop in Pembroke that had been picked up near that town.
