The Noisy Miner (Manorina melanocephala) is a member of the honeyeater family Meliphagidae, endemic to eastern and southeastern Australia. This robust bird is predominantly grey with a black crown, a vivid yellow patch behind the eye, and a striking orange-yellow bill and legs. The tail is adorned with white tips, and the wings have a subtle yellow-olive panel. Both sexes and juveniles share a similar plumage, though the young are a tad browner.
Adult Noisy Miners measure between 24-28 cm in length, with a wingspan of 36-45 cm, and weigh around 70-80 grams. They can be identified by their grey back, tail, and breast, white underparts with scalloping, and a distinctive yellow patch behind the eye. The bill is bright orange-yellow, and the tail has a prominent white tip. Juveniles are distinguishable by their softer, brownish-grey plumage and a less vivid yellow patch behind the eye.
The Noisy Miner thrives in dry, open eucalypt forests devoid of understory shrubs. It is commonly found in degraded woodland, recently burned areas, farming and grazing areas, roadside reserves, and suburban parks and gardens that feature trees and grass but lack dense shrubbery.
This species is found in a broad arc from Far North Queensland through New South Wales and Victoria to Tasmania and southeastern South Australia. It is sedentary across its range.
Noisy Miners are highly social and territorial birds, forming colonies that can number in the hundreds. They engage in communal activities such as foraging, bathing, roosting, breeding, and defending their territory. Their social structure includes 'coteries' and temporary 'coalitions' for specific activities like mobbing predators.
The Noisy Miner is aptly named for its extensive vocal repertoire, which includes a variety of songs, calls, scoldings, and alarms. Vocalisations are almost constant, especially from young birds. Alarm calls vary in frequency and are used to signal the presence of predators or to initiate mobbing behavior.
Breeding occurs year-round, with a peak from July to November. The female builds a deep cup-shaped nest and lays two to four eggs. Incubation is solely by the female, but up to twenty male helpers may assist with caring for the nestlings and fledglings.
The Noisy Miner can be confused with the Yellow-throated Miner and the Black-eared Miner. However, it can be distinguished by its dull white forehead and black crown, as opposed to the grey heads of the others.
The diet consists mainly of nectar, fruit, and insects. The Noisy Miner forages in the canopy, on trunks and branches, and on the ground. It can meet most of its nutritional needs from manna, honeydew, and lerp gathered from eucalypt foliage.
The Noisy Miner is classified as Least Concern by the IUCN. However, its aggressive territorial behavior and high population densities in some areas pose a threat to other bird species, leading to reduced avian diversity in human-affected landscapes.
