Old World Warblers (Sylviidae)

Dartford Warbler (Sylvia undata) - HBW 11, p. 699

French: Fauvette pitchou German: Provencegrasmücke Spanish: Curruca Rabilarga

Taxonomy: Motacilla undata Boddaert, 1783, Provence, France.
Apparently more closely related genetically to S. deserticola than to either S. sarda or S. balearica, although more similar in appearance to last two. Forms a clade with these three species, all four being part of a larger group that also includes S. conspicillata, S. cantillans, S. melanocephala, S. mystacea, S. rueppelli, and S. melanothorax. Geographical variation rather limited and partially clinal; nominate race intergrades widely with dartfordiensis in SW France and NW Iberia and with toni in S Iberia. Propose.. View all taxonomy...

Taxonomy: Motacilla undata Boddaert, 1783, Provence, France.
Apparently more closely related genetically to S. deserticola than to either S. sarda or S. balearica, although more similar in appearance to last two. Forms a clade with these three species, all four being part of a larger group that also includes S. conspicillata, S. cantillans, S. melanocephala, S. mystacea, S. rueppelli, and S. melanothorax. Geographical variation rather limited and partially clinal; nominate race intergrades widely with dartfordiensis in SW France and NW Iberia and with toni in S Iberia. Proposed races corsa (from Corsica) and naevalbens (SE Italy) fall within range of variation of nominate and thus are synonymized with it; similarly, aremoricus (from NW France) is synonymized with dartfordiensis, and tingitana (from Morocco) with toni. Three subspecies recognized.

Subspecies and Distribution:

  • dartfordiensis Latham, 1787 - S England and W France S to extreme N Iberian Peninsula.
  • undata (Boddaert, 1783) - S France, Iberian Peninsula, Balearic Is (Menorca, locally in N Mallorca), Corsica, Sardinia and Italy (including parts of Sicily).
  • toni E. J. O. Hartert, 1909 - NW Africa (NE Morocco E to N Tunisia), and perhaps S Iberia; non-breeding S to N edge of Sahara.
