What is "manorina"

Manorina is a genus of Australian endemic honeyeaters, containing four species: the black-eared miner (M. melanotis) the yellow-throated miner (M. flavigula), the noisy miner (M. melanocephala) and the bell miner (M. melanophrys). The genus is notable for the complex social organisation of its species, which live in colonies that can be further subdivided into coteries and nest contingents.
