Melifago dal bargiglio occidentale

Anthochaera lunulata

Melifago di medie-grandi dimensioni che si trova nell'Australia sud-occidentale, tipicamente nella macchia e nei boschi costieri secchi. Marrone grigiastro complessivamente con sottili striature bianche; punte chiare alle penne della coda e castano nelle penne primarie più facilmente osservabili in volo. Facilmente distinguibile dal Melifago caruncolato rosso per l'assenza di caruncole rosa sotto l'occhio e l'assenza di ventre inferiore giallo. Spesso trovato vicino a Banksia in fiore, dove è tipicamente molto attivo e vocale, con richiami aspri, forti e strillanti.

Identificazione

The adult western wattlebird has dark grey-brown upper-parts with pale streaks and spots. It has a dark brown forehead, crown and nape, streaked with fine, whitish shafts. Underparts are dark grey, streaked and tipped white. It has a blackish-brown streak bordering the eye, and has a red iris.<p>A large honeyeater, it is long and slender. A sample of the genders recorded sizes of 29–33 centimetres in length, 65–78 grams in weight for the males; and 27–30 cm and 47–57 g for the females. The weight range for unsexed birds is 45.5–83 grams.

Tassonomia

The species description was published by John Gould in 1838, from a specimen collected at the Swan River and held at "Fort Pitt, Chatham collection". The entry in his The Birds of Australia (1848) gives a common name of "Lunulated Wattle-Bird", and notes that the colonists referred to it as the little wattlebird.A treatment as a western population of the species Anthochaera chrysoptera, and thus conspecific with the 'little wattlebird' group of the eastern states, is cited by some authorities. Both species are assigned to the subgenus Anthochaera (Anellobia), taking its name from the generic description of Jean Cabanis (1851). Other workers regard this as a separate species, A. lunulata, based on morphological and plumage differences, and a different eye colour in these two populations. The taxonomy enthusiast, G. M. Mathews, published a description as the subspecies Anthochaera chrysoptera albani in his Austral Avian Record (1923), now regarded as a synonym for this species.<p>The epithet lunulata 'crescent-shaped' is derived from Latin lunula for 'little moon'.
