Factors influencing the post-fledging period and timing of dispersal in Bobelli's eagles Hieratus fasciatus in southwestern Spain

We studied factors influencing the length of the post-fledging period (from fledging to the start of dispersal) of Bonelli’s Eagle (Hieraaetusfasciatus) nestlings in soutlswestern Spain, using 13 nestlings equipped with radiotransmitters. The age at fledging was negatively correlated with hatching d...
