Résumé :
Abstract The sperm of the Eurasian Bullfinch (Pyrrhula pyrrhula) differs markedly in gross morphology from that of all other passerines examined to date. In other passerines, the sperm head is pointed and helical, and the midpiece comprises a mitochondrial helix extending along the flagellum; whereas in the Eurasian Bullfinch, the sperm acrosome is rounded, not helical, and the midpiece is extremely short. In a pairwise study, using principal component analysis (PCA), we combined quantitative and qualitative sperm morphology traits and conducted a phylogenetic correlation to compare the sperm

Résumé :
The Brown Bullfinch (Pyrrhula nipalensis) is a passerine bird within the family Fringillidae. This study reports the first photographic record of the Brown Bullfinch from the Gurez Valley, Jammu and Kashmir, India. The bird was sighted through a camera trap installed in Butamali Tullail, a meadow for herders at an altitude of 3,400 meters. This shy bird typically forages in pairs or small flocks and feeds on seeds, berries, and buds. The Brown Bullfinch thrives in dense temperate forests and breeds from May to July. It constructs well-concealed nests in shrubs or low trees, and both parents pa

Résumé :
Over the past hundred years, constant uncertainty has been observed in establishing the taxonomic status of individual forms of bullfinches, one that has been developed throughout the history of their study. The lack of information has prevented almost all researchers who worked on bullfinches from coming to generallly accepted conclusions. This has not changed even as a result of the use of molecular genetic methods. To analyze the current situation, three key publications are considered, on which the modern understanding of the history of phylogenetic interactions of closely related forms of

Résumé :
The paper surveys the history of composition of Gavriil R. Derzhavin’s The Bullfinch (1800), a famous poem on the death of the celebrated Russian military commander Alexander V. Suvorov (1730–1800). An analysis of three versions of these elegiac stanzas demonstrates how Derzhavin consistently improved his style and metrics (the poem is written in a rare logaoedic verse form). A comparison of all editions and manuscripts makes clear that Derzhavin did not notice a typographical error in the twenty-second line of The Bullfinch in the second part of his Works, which was published in 1808 in Saint

Résumé :
A new species of extinct bullfinch, Pyrrhula crassa n. sp., is described from bones found in Furna do Calcinhas, a small cave situated at Caldeira, a volcano located in the southeastern portion of the Graciosa Island (Azores archipelago, North Atlantic Ocean). It is the first extinct passerine bird to be described from this archipelago. Both skull and post-cranial bones are larger in the new species than in its relatives, the Eurasian Bullfinch (P. pyrrhula) and the Azores Bullfinch or “Priolo” from São Miguel Island (P. murina), the new species being the largest known in this genus.

Résumé :
Hybridization occurs among many bird species in nature and many more in captivity, and hybridization has important implications for the speciation process. Bird-fanciers have produced hybrids between the canary (Serinus canaria) and various finch species since at least 1600. Some finch species exhibit unidirectional hybridization in which males of species A can successfully hybridize with females of species B, but not vice versa. The bullfinch (Pyrrhula pyrrhula) is thought to be such a species, with only females capable of producing hybrid offspring with the domesticated canary and other finc

Résumé :
The Azores bullfinch (Pyrrhula murina Godman, 1866) is a rare Passeriformes endemic from the eastern part of São Miguel Island, Azores, Portugal. This bird was almost considered extinct in the first half of the 20th century, but due to recent conservation measures, it has experienced a recovery since the beginning of the 2000s. Despite the attention given to this bird, the size of its population is still controversial, and the most recent studies present significant divergences on this behalf. The purpose of the present study is to present data from the long-term monitoring and results of the

Résumé :
I studied the seasonal variation in habitat selection, diet, food supply and food selection of the Priolo or Azores bullfinch, Pyrrhula murina. This species and its associated habitat, the Azorean native cloud forest, are poorly known and are threatened by afforestation and the invasion of exotic flora. In addition detailed studies of these aspects are lacking for oceanic island birds. Throughout this study a comparison between the ecology of the Priolo and that of mainland Bullfinches is made. The primary aims of this study were (1) to evaluate the importance of three alternative hypotheses i
