Taxonomy
The large-billed scrubwren was described by ornithologist John Gould in 1838.
The generic name Sericornis derives from
It was placed in the
There are three recognised subspecies: Sericornis magnirostra magnirostra, S. m. viridior, and S. m. howei.[6]
Description
The large-billed scrubwren is 11.5 to 13 cm (4.5 to 5.1 in) in length and weighs 10 g (0.35 oz).[7][6] It has a dark reddish-brown eye in a pale buff face, with a longish, black bill inclined slightly upwards.[7][8] The upperparts are light grey-brown with an olive tint, the throat is a pale buffy-white, the belly greyish, and the rump and tail light rufous-brown.[8]
Distribution and habitat
The large-billed scrubwren is found from near
Behaviour
Breeding
The large-billed scrubwren breeds from July to January, mainly in November and December.[8][6] It constructs a rough, domed nest of bark, grass and moss, lined with feathers and set in creepers, tree-ferns or palm-fronds.[7][6] It often occupies the abandoned nest of other species, notably the yellow-throated scrubwren (Neosericornis citreogularis).[8][7] A clutch of 3 or 4 eggs, measuring 19 mm × 15 mm (0.7 in × 0.6 in), is laid.[8] The eggs are dull white to pale purplish-brown in appearance with fine spots at the large end.[7] The incubation period is unknown and the nestling period is about 13 days.[6] The nests are parasitised by the fan-tailed cuckoo (Cacomantis flabelliformis) and the chestnut-breasted cuckoo (C. castaneiventris).[6]
Feeding
The large-billed scrubwren forages in the low to middle levels of the forest, often in small flocks.
Vocalization
The large-billed scrubwren is mostly silent, but occasionally makes a penetrating territorial call "s-cheer s-cheer", a sharp, loud "chwip-chwip" or a chattering "sip-sip" while feeding.[8][7]
Conservation status
The large-billed scrubwren has a wide distribution and a stable population, and is classified as of
