BIRD LIFE THROUGHOUT THE YEAR
shelter of overhanging ledges in the thick of the seabird colony, just as they do on many a limestone cliff inland, as in Derbyshire or West Yorkshire. Such must have been the original nesting haunts of the species as a whole until, with the advent of housebuilding man, a large proportion of them came to utilize his eaves. The list of these associates and allies might be extended—we have found a corncrakes' nest upon a lonely islet amongst the terns' eggs, which lay so thickly that it was impossible to avoid treading on them—but those which have been mentioned are the most ordinary supernumeraries in scenes where the sea-birds themselves play the chief part.
