Abstract
We report some nesting and breeding parameters of the reed warbler in reedbeds patches. The nests were found only in pure reedbeds characterised by young stems, above or near water or on dry ground. In average, each nests was built on 3.06 Phragmites stems (± 1.06, range: 2-5, n = 16), at 1.31 m of height (0.31 ± , range from 0.70 to 2; n = 17). The average size of broods observed was determined to be 3.75 (± 0.75, range 2-5, n = 12). We observed 2.89 chicks (± 1.76, range 0-5, n = 9) in the 12 nests in which eggs were found.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
