Differential movement patterns of juvenile Tengmalms owls (Aegolius funereus) during the post-fledging dependence period in two years with contrasting prey abundance. [PDF]

PLoS ONE, 2013
Fledgling behaviour and movement patterns throughout the post-fledging dependence period (PFDP), especially in relation to changing environmental conditions, have been rarely studied, despite the fact that this period is recognized as of crucial ...

Factors affecting vocalization in Tengmalm's owl (Aegolius funereus) fledglings during post-fledging dependence period: scramble competition or honest signalling of need? [PDF]

PLoS ONE, 2014
Begging behaviour of nestlings has been intensively studied for several decades as a key component of parent-offspring conflict. There are essentially two main theories to account for intensity of food solicitation among offspring: that intensity of ...

Post-fledging survival of Tengmalm’s owl offspring in boreal forests: Interactive effects of varying dynamics of main prey and habitat composition

Frontiers in Ecology and Evolution, 2023
The knowledge about the mortality rate of offspring is crucial for estimating bird population dynamics and conserving species with declining populations.

Survival rates and causes of death in Tengmalm’s owl offspring during the post-fledging dependence period in Central and North Europe

Frontiers in Ecology and Evolution
Offspring survival rates in altricial birds during the post-fledging period are an essential factor in determining the fitness of parents and have a significant impact on general population dynamics.

Re-introduction of the Saker Falcon (Falco cherrug) in Bulgaria - preliminary results from the ongoing establishment phase by 2020 [PDF]

Biodiversity Data Journal, 2021
Considered extinct as breeding species in the early 2000s, the Saker Falcon was recovered when the first active nest from the new history of the species in Bulgaria was discovered in 2018, formed of two birds that were re-introduced back in 2015 ...

Observations of Red-headed Falcon Falco chicquera (Aves: Falconiformes: Falconidae) nest at Keraniganj, Dhaka, Bangladesh, with a focus on post-fledging behavior

Journal of Threatened Taxa, 2015
A nest of Red-headed Falcon Falco chicquera was observed in 2009, beginning with the onset of breeding and continuing on to the next breeding of the pair.

Post-fledging dependence period, dispersal movements and temporary settlement areas in saker falcons (Falco cherrug)

Raptor Journal, 2021
Information on mortality rates and their causes in raptors and owls during the post-fledging dependency period (PFDP) and subsequent dispersal is essential for their more effective protection, including more efficient use of funds. Despite the importance

Timing of departure from natal areas by golden eagles is not constrained by acquisition of flight skills

Journal of Avian Biology, 2023
The post‐fledging dependence period (PFDP), which extends from a fledgling's first flight out of the nest to its departure from the parents' territory, is crucial in the lifecycle of birds.
