abstract = "Variation of wing pointedness index between groups of juveniles captured in different months (July, August, and September) and at different stages of juvenile moult was studied in three Acrocephalus warbler species captured on the Courish Spit on the Baltic Sea. Sedge warblers (Acrocephalus schoenobaenus) captured in July had less pointed wings than sedge warblers captured in August or September. Marsh warblers (A. palustris) showed no significant difference between birds in early and in late moult. No differences in wing pointedness were found between different cohorts of reed warblers (A. scirpaceus), including known locally hatched birds and late migrants captured in September.
