Unlike nest 1, the nest base had a few tree leaves and leaf pieces incorporated into it. The entire inner nest-lining 'basket' consisted of the supple straw-coloured stems of epiphytic orchids up to 550 mm long and mm in diameter, with a few black tendril-like rootlets or stems up to 760 mm long. Nest 3 This nest was found on 21 December under construction, being built of moss and filmy fern fronds, but lacking a chamber lining of orchid stems. A silent female-plumaged Loria's Bird watched us at this nest; The nest was c. 200 m from nest 1 on a bearing of 130°, on the opposite side of the same stream (Fig. 2) in mature moss forest on a 45—50° slope falling to the NNE. This nest was extremely cryptic in situ, its materials perfectly matching living plants growing on immediately adjacent rock faces. When complete, nest materials were similar to nest 1 but the external appearance was dominated by fresh deep-green and blue-green filmy fern fronds {Hymenophyllum spp.) rather than by moss. Several fern fronds were placed below the entrance perch. Some 33 straight sticks, up to 305 mm long and mm in diameter, were in part or entirely visible on and in the front of the nest below the entrance perch. The inner nest-lining was predominantly of supple straw-coloured orchid stems, with several other fine woody tendrils, up to 600 mm long and mm in diameter. The base of the nest was a most substantial accumulation of filmy ferns laid atop one another t
