Brown Thrasher (Toxostoma rufum) Science Article 8 abstract Population of Brown Thrashers (Toxostoma rufam) nesting on the Konza Prairie Research Natural Area in northeastern Kansas. We determined whether thrashers reuse nests constructed in previous years, and tested predictions of the hypothesis that old nests function to reduce the risk of nest predation by saturatingt he […]

Incidental Cache Use by the Brown Thrasher, with Notes on Secondary Cache Use by Additional Avian Species
Brown Thrasher (Toxostoma rufum) Science Article 11 abstract Food hoarding is a widespread and complex behavior (Vander Wall 1990). Most research has focused on cache placement or food recovery by the hoarding animal, or on cache theft by conspecifics or by other food-hoarding species. Here, I document the way in which Brown Thrashers (Toxostoma rufum) […]

Structural conservation and variation in the mitochondrial control region of fringilline finches (Fringilla spp.) and the greenfinch (Carduelis chloris
Brambling (Fringilla montifringilla) Science Article 1 abstract We sequenced the entire control region and portions of flanking genes (tRNAPhe, tRNAGiu, and ND6) in the common chaffinch (Fringilla coelebs), blue chaffinch (F. teydea), brambling (F. montifringilla), and greenfinch (Carduelis chloris). In these finches the control region is similar in length (1,223-1,237 bp) and has the same […]
Abundance of owls and Bramblings Fringilla montifringilla inrelation to mast seeding in south-eastern Sweden
Brambling (Fringilla montifringilla) Science Article 2 abstract We investigated the relationship between mast seeding in beech Fagus sylvaticus and oak Quercus spp., and the occurrence of the rodent-dependent predators Tengmalm’s Owl aegolius funereus, Long-eared Owl Asio otus and Tawny Owl Strix aluco in south-eastern Sweden (Blekinge) 1992-2000. We also compared available data on seed production […]
A phylogenetic analysis of the evolution of moultstrategies in Western Palearctic warblers (Aves:Sylviidae)
Bonellis Warbler (Phylloscopus bonelli) Science Article 1 abstract Adult birds replace their flight feathers (moult) at least once per year, either in summer aftertermination of breeding or (in the case of some long-distance migratory species) in the winterquarters. We reconstructed the evolutionary pathways leading to summer and winter moultusing recently published molecular phylogenetic information on […]
Genetically confirmed interbreeding between western Bonelli’s warbler ( Phylloscopus bonelli ) and wood warbler ( P. sibilatrix )
Bonellis Warbler (Phylloscopus bonelli) Science Article 2 abstract During May and June 2003, a mixed breeding pair consisting of a male western Bonelli’s warbler (Phylloscopus bonelli) and a female wood warbler (P. sibilatrix) successfully raised six young in a broad-leafed forest near Junkerath, western Germany, an area far outside the regular breeding range of P.

An observation of attempted interspecific kleptoparasitism between two neotropical Tyrannid flycatchers
Boat-billed Flycatcher (Megarynchus pitangua) Science Article 1 abstract Kleptoparasitism, the interspecific and intraspecific stealing of already procured food, is well known among many taxa of birds (Brockmann & Barnard 1979), but has been reported only rarely in the avian family Tyrannidae. To my knowledge there are only two published observations of kleptoparasitism by tyrannid flycatchers, […]
SOCIALO RGANIZATIONO F THE BLUE-BACKEDMANAKIN
Blue-backed Manakin (Chiroxiphia pareola) Science Article 1 abstract The manakins of the genus Chiroxiphia are peculiar in that pairs of males (or in C. caudata several males) perform a coordinated courtship dance in which each bird appears to play an equal part. The displays take place on low perches in the undergrowth of secondary forest, […]
