Nestling growth of birds can be affected by weather fluctuations.In general,it is expected that higher temper-atures favor growth by improving food availability and nestling metabolism,while rain hinders it by reducin...

Sequence and intensity are two essential components of bird moult.While the moult sequences of remex tracts are highly homogenous across passerines,other tracts apparently show a high variability.Moreover,order of mou...

Long-distance migratory birds often face major geographical barriers on their journey.While some species are able to cross them,others use longer routes to avoid such barriers.Little is known about the strategies of S...

The hypothalamic-pituitary-gonadal(HPG)axis ubiquitously regulates seasonal reproduction,following the rhythmicity of a suite of environmental cues.Birds display prominent seasonal variations in gonad size regulated b...
This research was partially supported with funding from Ministero dell’Istruzione dell’Universita`e della Ricerca,PRIN 2003053710_005;Throughout the 22 years,ringing permits were released every other year by the competent Italian authority(Istituto Superiore per la Protezione e la Ricerca Ambientale,Bologna).
The increase in the average air temperature due to global warming has produced an early onset of the reproduction in many migratory birds of the Paleartic region.According to the“mismatch hypothesis”this response ca...
Background:Accurate nestling age is valuable for studies on nesting strategies,productivity,and impacts on repro-ductive success.Most aging guides consist of descriptions and photographs that are time consuming to rea...

DEAR EDITOR,Previous work based on molecular evidence has shown that most socially monogamous birds follow a genetic polyandrous mating system.However,our knowledge about avian mating systems is heavily biased toward ...
