Post-fledging period and dispersal of young SparrowhawksAccipiter nisus
Bird Study, 1985Eight nestling Sparrowhawks in Northamptonshire were marked with radiotransmitters to determine fledging and dispersal dates and the distances and directions travelled away from the nest. One male left the nest at 26 days old and dispersed 28 days later. Females fledged at 28–30 days old and dispersed 25–27 days later.

Abstract. In eastern North America, after the young fledge, both adult and juvenile mature-forest birds may use regenerating clearcuts, although which species frequent early-successional forest and during which life stages is not well documented. To assess whether birds nesting in mature forest in north-central Minnesota use regenerating clearcuts 2–10

The post‐fledging dependence period (PFDP) is a fundamental stage in the life cycle of altricial birds that influences their long‐term survival and fitness. However, research on the duration of this period in raptors, and on the factors affecting it, is scarce.

We studied the role of early developed phenotypic characters associated to body size (i.e., tarsus, wing, and tail length) together with body mass in the determination of the winter residence and r...

Ardeola, 2012
Summary.—Space-use strategies are essential behavioural skills during the fledging-to-dispersal period, when physical capabilities and the ability to explore the external world are developed. Here we describe the space-use strategies of 13 radio-tagged ospreys Pandion haliaetus, released as part of a reintroduction project in Central Italy, during ...

Play bouts and active training of juveniles by Montagu’s harrier (Circus pygargus) adults in the post-fledging period were observed. Fledglings often played with prey and with a variety of inanimate objects such as bits of moss, regurgitated pellets, sticks and a wad of hay.
