On April 12th we found numbers of nests of this bird

 bushes close to the shore of the harbour. Some of the nests 

 were fully seven feet from the ground. The building materials 

 used were fine dead grass and small twigs of the lavender-

 contained either four or five eggs, but the former complement 

 was more general.
