Carduelis Carduelis

Avian trichomonosis is a common and widespread disease, traditionally affecting columbids and raptors, and recently emerging among finch populations mainly in Europe. Across Europe, finch trichomonosis is caused by a single clonal strain of Trichomonas gallinae and negatively impacts finch populations. Here, we report an outbreak of finch trichomonosis in the wintering populations of Chloris chloris (European greenfinch) and Carduelis carduelis (European goldfinch) from the Boulonnais, in northern France. The outbreak was detected and monitored by bird ringers during their wintering bird ringing protocols. A total of 105 records from 12 sites were collected during the first quarter of 2017, with 46 and 59 concerning dead and diseased birds, respectively. Fourteen carcasses from two locations were necropsied and screened for multiple pathogens; the only causative agent identified was T. gallinae. Genetic characterization was performed by four markers (small subunit ribosomal RNA, hydrogenosomal iron-hydrogenase, and RNA polymerase II subunit 1 genes, and the internal transcribed spacers (ITS) region) and confirmed the T. gallinae strain to be A1, which affects the finch populations of Europe. This was also confirmed by an ITS-based phylogenetic analysis which further illustrated the diversity of the Trichomonas infecting birds. Preliminary data on the survival and dispersion of infected birds were obtained from ring-returns of diseased individuals. The anthropogenic spread of diseases through bird feeding practices is highlighted and some suggestions to prevent pathogen transmission via backyard supplementary feeders for garden birds are given.

Abstract In 2017 the European Goldfinch (Carduelis carduelis) was voted to be the “bird of the year” in Hungary. This is a partially migrant species; most of the European populations are resident, however, its breeding range extends to East from the Sweden-Poland-Moldova axis towards the Yenisei with some of the populations wintering in Kazakhstan and South of Turkey. The European Goldfinch is classified within the Carduelinae subfamily including approximately a hundred species. Several taxonomic changes were introduced in this group during the last fifteen years, however, we still do not understand much of their origin and evolutionary history. My aim in this paper is to collect existing knowledge on the phylogeny and evolution of the Carduelinae finches and their allies, with a particular focus on the European Goldfinch and its closest relatives. Furthermore, here I point out uncertainties in different phylogenetic sources of finches, which careful consideration can be useful in similar evolutionary studies. Finally, I summarise some vision for future research.
