The name mocking-bird, or more frequently mock-nightingale, is in England occasionally given to some of the warblers (q.v.), especially the blackcap (Sylvia atricapilla), and the sedge-bird (Acrocephalus schoenobaenus).
We have homely genera, even among the true Passeres, occurring there - such as Alauda, Acrocephalus, Motacilla and Pratincola, while the Cisticola madagascariensis is only distinguishable from the well-known fan-tailed warbler, C. schoenicola of Europe, Africa and India by its rather darker coloration.
