|Title:||The role of intense net predation in the decline of Scarlet Robins and Eastern Yellow Robins in remnant woodland near Armidale, New South Wales||Contributor(s):||Debus, SJS (author)||Publication Date:||2006||Handle Link:||https://hdl.handle.net/1959.11/223||Abstract:||A study of open-nesting Eastern Yellow Robins 'Eopsaltria australis' and Scarlet Robins 'Petroica multicolor', on the New England Tablelands of New South Wales in 2000-02, found low breeding success typical of eucalypt woodland birds. The role of intense nest predation in the loss of birds from woodland fragments was investigated by means of predator-exclusion cages at robin nests, culling of Pied Currawongs 'Strepera graculina', and monitoring of fledging and recruitment in the robins. Nest-cages significantly improved nest success (86% vs 20%) and fledging rate (1.6 vs 0.3 fledglings per attempt) for both robin species combined (n = 7 caged, 20 uncaged). For both robin species combined, culling of currawongs produced a twofold difference in nest success (33% vs 14%), a higher fledging rate (0.5 vs 0.3 per attempt), and a five-day difference in mean nest survival (18 vs 13 days) (n = 62 nests), although sample sizes for nests in the cull treatment (n = 18) were small and nest predation continued. Although the robin breeding population had not increased one year after the cull, the pool of Yellow Robin recruits in 2001-03, after enhanced fledging success, produced two emigrants to a patch where Yellow Robins had become extinct. Management to assist the conservation of open-nesting woodland birds should address control of currawongs.||Publication Type:||Journal Article||Source of Publication:||Pacific Conservation Biology, 12(4), p. 279-287||Publisher:||Surrey Beatty & Sons Pty Ltd||Place of Publication:||Sydney, Australia||ISSN:||1038-2097||Field of Research (FOR):||060207 Population Ecology||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Other Links:||http://pcb.murdoch.edu.au/toc/pcb_contents_v12.html#issue4||Statistics to Oct 2018:||Visitors: 33
