high chromosome conservation detected by comparative chromosome painting in chicken, pigeon and passerine birds.chicken chromosome paints for macrochromosomes 1-10, z, and the nine largest microchromosomes (griffin et al. 1999) were used to analyze chromosome homologies between chicken (gallus gallus domesticus: galliformes), domestic pigeon (columba livia: columbiformes), chaffinch (fringilla coelebs passeriformes), and redwing (turdus iliacus: passeriformes). high conservation of syntenies was revealed. in general, both macro- and microchromosomes in these birds showed very low levels of interchromosoma ...200415505406
deadly outbreak of iron storage disease (isd) in italian birds of the family turdidae.a widespread deadly outbreak occurred in captive birds belonging to the family turdidae in italy. the present study was performed on 46 dead birds coming from 3 small decoy-bird breeders in central italy. only turdus pilaris, turdus iliacus, turdus philomelos and turdus merula were affected. no other species of bird held by these breeders died. a change of diet before the hunting season was reported from all breeders. full necropsy of the animals and histological investigations of representative ...201424920545
molecular characterization and distribution of haemoproteus minutus (haemosporida, haemoproteidae): a pathogenic avian parasite.recently, the lineage hturdus2 of haemoproteus minutus (haemosporida, haemoproteidae) was reported to cause mortality in captive parrots. this parasite lineage is widespread and prevalent in the blackbird turdus merula throughout its entire distribution range. species identity of other closely related lineages recently reported in dead parrots remains unclear, but will be important to determine for a better understanding of the epidemiology of haemoproteosis. using polymerase chain reaction (pcr ...201323557683
heterospecific attraction and food resources in migrants' breeding patch selection in northern boreal forest.we studied experimentally how heterospecific attraction may affect habitat selection of migrant passerine birds in finnish lapland. we manipulated the densities of resident tit species (parus spp.). in four study plots residents were removed before the arrival of the migrants in the first study year, and in four other plots their densities were increased by releasing caught individuals. in the second year the treatments of the areas were reversed, allowing paired comparisons within each plot. we ...199828308463
[monomers of a satellite sequence of chaffinch (fringilla coelebs l., aves: passeriformes) genome contains short clusters of the tttaggg repeat].a novel repeated sequence of chaffinch (fringilla coelebs) designated as gs was isolated from genomic dna after in vitro amplification of satellite dna sequences using gsp-pcr technique. the proportion of this repeat in the chaffinch genome constitutes about 2%. monomers are 176 to 199 bp in size and contain a short cluster of the ttaggg telomeric tandem repeat. the oligomer of the telomeric hexanucleotide is flanked by the sequences that are significantly different in different monomers. the gs ...200212575444
redescription of monorcholepis dujardini (krabbe, 1869) and m. passerellae (webster, 1952) (cestoda: cyclophyllidea: aploparaksidae) in passerine birds from the holarctic region.two species of avian tapeworms, monorcholepis dujardini (krabbe, 1869) and m. passerellae (webster, 1952), of the cyclophyllidean family aploparaksidae mayhew, 1925 (earlier included in the hymenolepididae) are redescribed. relative to congeners, the morphology of the strobila of both species shows strong similarities including a unique form of the cirrus. separation of these species, however, can be based on the number (40-53 and 25-31, respectively) and size (18-25 microm and 14-18 microm) of ...200717441439
inter-specific and intra-specific variability in fruit color preference in two species of of the main hypotheses proposed to explain the evolution of fruit color deals with a preference of avian frugivores for specific colors, mainly black and red, which are the most common fruit colors in many of the studied habitats. i analyzed fruit color preferences by wild birds belonging to 2 species of the highly frugivorous genus turdus (eurasian blackbird turdus merula linnaeus, 1758 and redwing turdus iliacus linnaeus, 1758) by means of captivity experiments with artificial fruits. desp ...201121910844
