| Résumé : | The mean hatching success of 1838 Pied Flycatcher clutches recorded from 1974 to 1999 amounts to 94.7% (without clutches destroyed by predators). Totally hatching failure was only found in six broods ( = 0.3% of all broods recorded). A sterile male was paired in 1997, 1998 and 1999. Some data refering to the unfertilized clutches are given in Table 2. |
