Pollo R., Bombieri R.



Abstract:

Survival rates of adult Melodious Warblers were estimated by capture-mark-recapture data, analyzing capture – histories of 169 individuals with the program SURGE. The annual adult survival rate was estimated at 54,1%. Breeding density in the study area was 16 – 18 pairs/8 ha in the 1992-95 period, whereas decreased to 13 pairs in 1996. Philopatry, phenology of migration and of reproduction are also discussed.
