Mangrove Honeyeater
Gavicalis fasciogularis
Medium-sized honeyeater found in coastal habitats of eastern Australia. Back is brown-green, breast is gray, and underparts are pale. Distinguished from Varied Honeyeater by presence of clear barring on the throat and lack of yellow underparts and breast streaking. Usually found in or around mangroves, where it is typically quite conspicuous and vocal.

The song is loud, melodious and ringing, but varying, e.g. “whit-u-we-u”. It is classified as scolding chatter. Small honeyeaters are often musical, while larger ones make a larger raucous sound.<p>The breeding period is between August–December. The peak month is September. In northern regions, the breeding period lasts between April–May. Their nests are cup-shaped and are made of dried grasses and seagrass or plant fibre, which are bound with spider web and matted egg sacs. They are lined with fine rootlets or fine grass. For two nests, the external diameter is 8·9–9·5 cm, the depth is 5·7–7·6 cm, and the internal diameter is 6·4–7·6 cm. Nests are suspended by rim, and occasionally supported, they are 0·5–2·7 m above ground. They are small in size, and are found in dense mangroves. Both adults feed nestlings and fledglings. Nests are parasitized by Pallid (Heteroscenes pallidus) and Fan-tailed Cuckoos (Cacomantis flabelliformis).<p>They are a local resident of Moreton Bay, in SE Queensland. The numbers increase in May–Jun and decline during Jul–Dec. This movement is a possible result of local seasonal changes.<p>The mangrove honeyeaters have benefited from land-clearing and fragmentation in southern Western Australia and are able to fly over open agricultural lands. They have been implicated in the spread of the noxious weed Bridal Creeper, Asparagus medeoloides.
保护状况
The mangrove honeyeater is not globally threatened. They have restricted range and the population size is not quantified, but is not considered vulnerable due to the size of its range. The range is thought to have expanded over the last 50 years, with first records if the bird at Yamba in 1947, and some following records farther south.

Dusky-cheeked Fig-Parrot
Nannopsittacus melanogenia
A small, short-tailed parrot of lowland forest and edge, mainly at low elevations. Green body with dark blue in the wing, and a dark forecrown and cheek. Males have a white line separating the cheek, crown and bill, and usually an orange chest. Female has a darker face, less orange on the breast, and an orange patch behind the dark cheek. Usually found in small groups. Most similar to Double-eyed Fig-Parrot, but Dusky-cheeked has blackish instead of red forecrown and cheek, and an orange breast. Calls a sharp, high-pitched “tsik!” or excited twittering which often betrays their presence in a tree.
Westland Petrel
Procellaria westlandica
Rather large, wholly dark petrel. Breeds in New Zealand and ranges across the temperate South Pacific to Chile, where it is uncommon to locally fairly common in the Humboldt Current and fjords. Often found with much commoner, but very similar White-chinned Petrel and is not easily identified unless distinct black bill tip of Westland can be seen (White-chinned has pale bill tip). Slightly smaller Parkinson’s Petrel looks very similar to Westland, but favors warmer tropical and subtropical waters and has a smaller, more rounded head and slightly slimmer bill.
Rusty-tailed Flycatcher
Ficedula ruficauda
Medium-sized brown flycatcher with an orangish tail. Note upright posture and broad-based pale bill. Forages quietly and usually singly in the lower levels of forest edge, both through gleaning and flycatching. Breeds in open forests in hilly and montane areas at 1500-3000 meters of elevation; in the winter, favors forest edge and clearings. Song is a descending whistle followed by a brief sputter of shorter notes: “Weee-pewchewchi!”
