Abstract

We evaluated results of over 4400 documented faecal parasitological examinations between 2000 and 2007 in more than 90 individuals of six species of Birds of Paradise (BoP). Between 2000 and 2007, 83.2% of investigated samples were negative for parasites, and the number of negative samples increased consistently over the years; in positive samples, the proportion of Capillaria sp decreased (from 100% to 4.8%) and that of Coccidia sp increased (from 0% to 67.5%). Differences in prevalence of endoparasites between species, epidemiological units (houses) and sexes were found. The Twelve-wired bird-of-paradise Seleucidis melanoleuca, which has the highest reported proportion of insects in its natural diet, had the highest prevalence of tapeworms, indicating a high propensity to ingest intermediate hosts. Coccidia sp were particularly prevalent in an epidemiological unit with high exposure to free-ranging birds. The number of offspring per female and year correlated with the percentage of negative samples taken in the according year and species. The results indicate that consistent antiparasitic management leads to a reduction of parasite species; that parasites with intermediate hosts are more difficult to control; that exposure to free-ranging birds should be minimized; and that a tight antiparasitic management potentially contributes to the improved breeding success in bird species.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
