Green Catbird
Ailuroedus crassirostris
Green catbirds are a medium-sized stocky bird with long, powerful legs and a long, stout bill. The back, wings and rump are brilliant emerald green, with very conspicuous pure white spots at the tips of the tertiaries and secondaries, which, on the tips of coverts, form two white wing-bars. The tail is brownish emerald with white tips. The head is greenish brown mottled black and finely flecked pale buff. The chest is greenish buff to dull emerald with distinctive short white streaks. The bill is horn coloured and the legs are greyish brown. Voice: The green catbird's call varies from a short, recognisable "heer-I-aar" to a long, drawn-out, quavering version: "heeeir-Ieee-aaa-aarr".

Satin Bowerbird
Ptilonorhynchus violaceus
Mature males have violet-blue eyes and are uniformly coloured black, however, light diffraction by the surface texture of the feathers results in an almost metallic sheen giving a deep shiny blue appearance. Immature males are coloured and marked the same as females and are often mistaken for them. Females might be mistaken for the green catbird or spotted catbird with distinctively green/brown or otherwise entirely brown upper body and lighter under body with a distinct reticulated or scalloped pattern, but with very striking blue eyes.
