Cecil Smith, Birds of Guernsey (1879)
“ I see no reason why it should not be more common in Guernsey than is usually supposed, as there are many places well suited to it, but its rather dull plumage, and its habit of hiding itself in thick furze-bushes, and creeping from one to another as soon as disturbed, contribute to keep it much out of sight, unless one knows and can imitate its call-note, in which case the male bird will soon answer and flutter up to the topmost twig of the furze-bush in which it may have previously been concealed, fluttering its wings, and repeating the call until again disturbed. ”
