“…Some investigators consider that marks on artificial eggs are unreliable indicators of nest predator identity (Major 1991;Major et al 1994, Brown et al 1998, Fulton & Ford 2003, but in our study, predator markings on artificial eggs were consistent with our observations of actual nest predation. Nest predation experiments using real or artificial eggs may change (elevate or decrease) nest predation rates because the di#ering odours of the eggs may attract or discourage predation by small mammals (e.g., Rangen et al 2000).…”

Abstract. Nest predation is high in mangals (mangrove communities) of the Australian monsoon tropics. The Large-billed Gerygone Gerygone magnirostris and Mangrove Gerygone G. levigaster are warbler-like birds that build domed nests, which are very di#erent from each other in size, form and colour. Large-billed Gerygone forages and builds nests along tidal creeks where vegetation is tall and dense, whereas Mangrove Gerygone primarily nests in shrubs around the edges of bare salt flats and forages in both habitats. Using artificial nests that mimicked those of the two species, we tested whether di#erences in nest appearance, including form and colour, were adaptations to avoid nest predation. Artificial Mangrove Gerygone nests in their main nesting habitat were predated less frequently than those on tidal creeks, whereas predation rates on artificial Large-billed Gerygone nests did not di#er between habitats. Our results suggest that Mangrove Gerygone nests are built in the primary breeding habitat to avoid nest predators. In addition, we identified a nest predator, the Yellow Oriole Oriolus flavocinctus.

“…The four artificial-nest treatments were: (a) artificially constructed nest with plasticine eggs; (b) artificially constructed nest with Canary eggs; (c) disused robin nest with plasticine eggs; and (d) disused robin nest with Canary eggs. Artificial nests were constructed from halved tennis balls covered in leaves, bark and lichen taken from species in the study area and attached with construction adhesive (Major et al 1994). They were 'aired' outdoors for four weeks to reduce odour.…”

Abstract. We compared the predation rate on natural nests of the Eastern Yellow Robin, Eopsaltria australis, with the predation rates on four types of artificial nests in a woodland remnant in southern Victoria. The aims of this study were: to compare the overall rates of predation on artificial and natural nests; to determine whether artificial nests accurately reflect the effects of nest-site characteristics on the predation rate of natural nests; and to examine the effects of using different nest types and egg types for artificial nests. The predation rates on artificial nests were significantly greater than those on natural nests. The predation rate was significantly greater on artificially constructed nests than on real, disused Eastern Yellow Robin nests, but there was no difference in the predation rates on artificial nests containing plasticine or Canary, Serinus canarius, eggs. There were no effects of nest-site characteristics on the predation rates on either artificial or natural nests. These results showed that the method of construction of artificial nests can affect the rate of nest predation, and suggest that artificial nests should be made as realistic as possible in order to gain more accurate information on the predation rates on the natural nests they are meant to represent.

“…Many of the bird species dependent on Australian eucalypt woodlands and forests are considered to be in decline Recher, 1999), and fragmentation-related increases in nest predation levels are one of the potential causes . Corvids, and the larger species of artamid (Artamidae, including species of butcherbird and currawong which are in many ways morphologically and ecologically similar to corvids), are important nest predators within Australian eucalypt forests and woodlands (Gardner, 1998;Taylor and Ford, 1998;Matthews et al, 1999;Major et al, 1994Major et al, , 1999Zanette and Jenkins, 2000;Bayly and Blumstein, 2001;Fulton and Ford, 2001;Piper et al, 2002). Many of these bird species increase in abundance near forest edges or become more common in human-modified landscapes following clearing of these habitats (Loyn, 1987;Catterall et al, 1991Catterall et al, , 1997aBarrett et al, 1994;Green and Catterall, 1998).…”
