Arrival times and biometric correlation in Sylviine warblers in Vojvodina, Serbia
Апстракт
Five of the 17 western Palearctic warblers of the genus Sylvia occur in Vojvodina, the northern province of Serbia. Of these, only two, the Blackcap (S. atricapilla) and Greater Whitethroat
(S. communis), are common, permanent breeding species in diverse forests and woods. Depending on weather conditions, most Blackcaps arrive in the second half of March on spring
migration, but both Greater and Lesser Whitethroats (S. curruca) are later, usually appearing in mid April. Within the last five years, the Lesser Whitethroat has begun to breed in northwest
Vojvodina, but only in very small numbers. The Barred Warbler (Sylvia nisoria), which arrives in early May, stays on to breed in still smaller numbers. The Garden Warbler (Sylvia borin) also
migrates through Vojvodina at the end of April or very beginning of May, but does not remain to nest. Using ringing data from the National Centre for Animal Marking, we analyzed 10878 ringing records of sylviine warblers from over ten years. The a...nalysis included biometric data such as wing length and age, which was correlated with the timing of movements in spring and autumn of adults and juveniles in all five species. No statistically significant biometric correlations were obtained for short-distance migrants, such as the Blackcap and Lesser Whitethroat. For long-distance migrants, however, a positive correlation was found between wing length and age in respective sexes. Wing length in the Greater Whitethroat was particularly dimorphic sexually and with age: males and older birds of both sexes are longer winged than females and juveniles, respectively. A similar relatioship was found in the Garden Warbler, in which older birds had longer wings, while Barred Warblers showed correlations between arrival date and age. Such relationships suggest further
correlations between molt and age.
