Markéta Zárybnická, Auteur ; Ondřej Sedláček, Auteur ; Pälvi Salo, Auteur ; Karel Šťastný, Auteur ; Erkki Korpimäki, AuteurEnvironmental variation across space and time can strongly influence life-history strategies in vertebrates. It has been shown that the reproductive success of birds of prey is closely related to food availability. However, relatively little is [...]![]()

Bowie, Auteur ; Ondřej Sedláček, Auteur ; David Hořák, Auteur ; Ulf Ottosson, Auteur ; Jan T. Lifjeld, AuteurBirds show considerable variation in sperm morphology. Closely related species and subspecies can show diagnostic differences in sperm size. There is also variation in sperm size among males within a population, and recent evidence from passerin[...]![]()

Article
Ondřej Sedláček, Auteur ; Roman Fuchs, AuteurWe investigated breeding patch fidelity and between-year territory movements in relation to breeding success and habitat characteristics in a colour-ringed urban population of the Common Redstart Phoenicurus phoenicurus. In 1996-2004, Ill marked[...]![]()

Ondřej Sedláček, Auteur ; Jana Vokurková, Auteur ; Michal Ferenc, Auteur ; Eric Nana Djomo, Auteur ; Tomáš Albrecht, Auteur ; David Hořák, AuteurAcoustic signals are frequently used for estimating avian species richness, abundance and community composition. However, sampling by traditional methods of bird surveys is often limited by availability of experienced researchers in the field, e[...]![]()

Do Tengmalm's Owls alter parental feeding effort under varying conditions of main prey availability?
Markéta Zárybnická, Auteur ; Ondřej Sedláček, Auteur ; Erkki Korpimäki, AuteurWe studied the diet composition and behavioural responses to variable food conditions in Tengmalm's Owls (Aegolius funereus). The abundance of main prey (voles and mice) of owls was higher in the Ore Mountains, Czech Republic, than in the Kauhav[...]![]()

Food niche differentiation in two syntopic sunbird species: a case study from the Cameroon Mountains
Jan Riegert, Auteur ; Drahomira Fainova, Auteur ; Marcin Antczak, Auteur ; Ondřej Sedláček, Auteur ; David Hořák, Auteur ; Jiri Reif, Auteur ; Michal Pesata, AuteurClosely related bird species can coexist in areas of range overlap due to differentiation of their ecological niches. If coexisting species have similar habitat requirements, separation of food niches presumably plays a crucial role. Theoretical[...]![]()

Jiri Reif, Auteur ; Ondřej Sedláček, Auteur ; David Hořák, Auteur ; Jan Riegert, Auteur ; Michal Pesata, Auteur ; Zaboj Hrazsky, Auteur ; Stepan Janecek, AuteurAlthough the high species richness and endemism of birds in the Bamenda Highlands has attracted ornithological research for decades, most studies have been restricted to bird communities of continuous montane forests. Instead, we focused on a mo[...]![]()

Ondřej Sedláček, Auteur ; Blanka Cikanova, Auteur ; Roman Fuchs, AuteurIt has long been hypothesized that birds learn to recognize heterospecific competitors and for that reason males behave more aggressively against intruders in areas of local sympatry. Recently, it has been confirmed that individuals of one speci[...]![]()

Eric Djomo Nana, Auteur ; Ondřej Sedláček, Auteur ; Jana Vokurková, Auteur ; David Hořák, AuteurNest predation is the leading cause of reproductive failure in birds and thus it shapes their life history strategies. Intensities of nest predation appear to differ among nest locations and types in both temperate and tropical regions. However,[...]
