Zitting Cisticola

• GeneralIt sews a purse-shaped nest among the grass stems with spider silk.
• It is the only European representative of the family Cisticolidae, which brings together some 110 species, almost all of them African.
• The male weaves the outer structure of the nest, an elongated pouch of grasses stitched together with cobweb, and the female finishes the inner lining; he builds several nests one after another to attract different females.
• Its Spanish name is bewildering for a bird of ten grams, and the local vernacular names poke fun at it: Cienlibras (hundredweight) in Doñana, Tumbabarcos (boat-sinker) in Huelva or Esclafamuntanyes (mountain-crusher) in Valencia.
• It is one of the smallest birds in Europe, and its Iberian folk names make fun of the fact: in Doñana it is called Cienlibras ("hundredweight"), in Valencia Esclafamuntanyes ("mountain-crusher") and in Huelva Tumbabarcos ("boat-toppler") or Bueyesito ("little ox"). It is very sensitive to cold: a cold snap can wipe out whole populations, as was documented in the Basque Country.
