On the phylogenetic position of the scrub-birds (Passeriformes: Menurae: Atrichornithidae) of Australia
Journal of Ornithology - - 2007
Evolutionary relationships of the scrub-birds Atrichornis were investigated using complete sequences of the recombination-activating gene RAG-1 and the proto-oncogene c-mos for two individuals of the noisy scrub-bird Atrichornis clamosus. Phylogenetic analysis revealed that Atrichornis was sister to the genus Menura (the lyrebirds) and that these two genera (the Menurae) were sister to the rest of......
Parental genetic characteristics and hatching success in a recovering population of Lesser Kestrels
Journal of Ornithology - Tập 151 - Trang 155-162 - 2009
Decreased hatchability is a common consequence of inbreeding in oviparous organisms and it has been generally considered a useful measure of the effects of reduced genetic diversity on embryological development. Here, we examined the pattern of hatching failure in a wild population of the endangered Lesser Kestrel (Falco naumanni). Particularly, we first analyzed long-term changes of hatching fail......
Predicting the potential distribution of the invasive Common Waxbill Estrilda astrild (Passeriformes: Estrildidae)
Journal of Ornithology - Tập 152 - Trang 769-780 - 2011
Human transport and commerce have led to an increased spread of non-indigenous species. Alien invasive species can have major impacts on many aspects of ecological systems. Therefore, the ability to predict regions potentially suitable for alien species, which are hence at high risk, has become a core task for successful management. The Common Waxbill Estrilda astrild is a widespread African speci......
Ultraviolet-blue plumage colouration can be perceived as an indicator of fluctuating asymmetry by Blue Tits (Cyanistes caeruleus)

Extent and symmetry of post-juvenile moult as predictors of future performance in Greenfinch Carduelis chloris
Journal of Ornithology - Tập 154 - Trang 465-468 - 2012
The extent of post-juvenile moult in passerines is highly variable, but the causes and consequences of such variability remain poorly understood. We tested the hypothesis that the extent and symmetry of post-juvenile moult of Greenfinches Carduelis chloris may be used as reliable predictors of their winter/spring body condition. We found a quadratic relationship between moult extent and the body m......
Nesting beside old nests, but not over water, increases current nest survival in a tropical mangrove-dwelling warbler

Influence of age on spatial and temporal migratory patterns of Black Storks from Germany
Journal of Ornithology - - 2024
How the migration behavior of long-lived birds develops throughout their life is still a research question in ornithology that is largely unanswered. Here, we analyzed GPS data of 70 juvenile Black Storks during the first 3 years of their migration to determine the influence of age and experience on migration patterns. We focused on the choice of the migration flyway, as well as the movements in t......
Great Reed Warbler singing behavior and conspicuous song structures are not nest-location cues for the Common Cuckoo
Journal of Ornithology - Tập 158 - Trang 925-933 - 2017
In some systems, brood parasites may be attracted by vocal or visual signals connected with host breeding. We studied a Great Reed Warbler (Acrocephalus arundinaceus) population where annually 30–50% of nests are parasitized by the Common Cuckoo (Cuculus canorus). We observed host males and quantified their song-related behaviors, including time spent singing, distance of movements and time spent ......
