The Melodious Warbler — Hypolais Polyglotta (Vieillot)
Although the presence of this species had long been suspected, as well as the possibility of it having bred with us, it was not until 1897 that the first authenticated example was procured at Burwash in Sussex. It is a southern species, breeding abundantly in Spain, North Africa, and South-Western France. Its eggs very closely resemble those of the Icterine Warbler.
Except for its smaller size, it is very difficult to distinguish this species from the preceding one, but its proportionately shorter wing, its larger bastard primary and the second primary being shorter than the fifth, form unfailing characteristics. Length 4·9 in.; wing 2·5 in.
