Distribution of the black-eared miner

The black-eared miner (Manorina melanotis) is an endangered honeyeater endemic to mallee woodland in south-eastern Australia.

Taxonomy

Manorina melanotis was identified by Francis Erasmus Wilson in 1911.[2] It is closely related to the much more widely distributed yellow-throated miner M. flavigula, and the taxonomic status of the black-eared miner is the subject of some controversy, with some researchers considering it a subspecies of M. flavigula.[3]

Behaviour

Black-eared miners are

co-operative breeders, living in colonies during the breeding season, and dispersing into the bush during non-breeding periods. Little is known of their movements during these periods.[3]

In 2022, it was reported that the species had been interbreeding with the yellow-throated miner.[4]

Distribution and habitat

IBA (Important Bird and Biodiversity Areas), identified by BirdLife International as being important for black-eared miner conservation, are areas containing relatively intact, mallee woodland in north-western Victoria and south-eastern South Australia. They comprise Murray-Sunset, Hattah and Annuello, the Riverland Mallee, and Wyperfeld, Big Desert and Ngarkat.[5]

Conservation status

Black-eared miners' survival became threatened by habitat clearance to make way for agriculture, and the bird experienced competition from goats, rabbits,

ornithologist John McLaughlin,[7] while a 2018 study ranked it as the 10th bird at most risk of extinction.[8]

As of 2022[update], there remain around 200 colonies, with up to 20 birds within each colony. Interbreeding with the yellow-throated miner has affected the genetic integrity of the black-eared miner, which adds to the risk to their population.[4]

The species is listed as endangered on the IUCN Red List (2021.3) and under the Australian Environment Protection and Biodiversity Conservation Act 1999,[2] and its conservation status in several Australian states is as follows:

Conservation measures

In July 2022, it was announced that AUD$125,000 has been dedicated to protect the black-eared miner. The Australian Government has provided the funding to the Murraylands and Riverland Landscape Board (MRLB) and their partners for the project.[12] As part of the project, researchers will do genetic testing of birds in the 200 populations.[4]
