The nest is generally placed in a lawyer vine up to 10 m (30 ft) above the ground. A clutch of one or two eggs is laid. The eggs are buff, cream- or greenish-white, and marked with light brown splotches and spots, usually concentrated around the large end, and measure 26 by 19 mm.

Birds are feathered, winged, bipedal, endothermic , egg-laying, vertebrate animals. Around 10,000 living species and 188 families makes them the most speciose class of tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic to the Antarctic. Extant birds range in size from...
