TJITTES AA (1959) First observation of the Dartford Warbler in the Netherlands. LIMOSA 32 (4): 185-188.

Dartford Warbler Sylvia undata During the first three days of April? 1959 a Dartford Warbler sojourned in some blackthornbushes at the coast of the Veluwe-Iake near Hoophuizen. The leader of an excursion of the N.J.N. (The Dutch young-people's Union for the Study of Nature) discovered the bird, which was afterwards seen by many members of that union and by the author. The bird was most looking like the figure of a first winter-female on Plate 40 of the Handbook of British Birds, volume II (1952). No song was heard.
