Breeding Biology, Chronology, and Reproductive Success of the European Serin (Serinus serinus) at Moulouya High Plain (Morocco)

Table 5

Failure factors reducing the breeding success (success of chicks = emancipation of chicks, success of eggs = hatching of chicks, success of nests = occupied by the breeders) of the European serin.
