Lichenostomus melanops cassidix
- Habitat degradation due to lack of regeneration of Mountain Swamp Gum and the consequences that come with it
- Nest disturbance by predators
- Competition with Bell Miner Honeyeaters for nest sites
The Helmeted Honeyeater, a medium-sized yellow-tufted honeyeater, is a perching bird species that now has a tiny population within the Yellingbo Nature Conservation Reserve in Victoria, Australia. It feeds mainly on nectar and small invertebrates like flies, crickets, and mealworms.
Helmeted Honeyeaters are on the brink of extinction with just less than 200 individuals in the wild due to extensive destruction of its nesting site – the Mountain Swamp Gum Trees. Siltation, waterlogging, and weed invasion within the surrounding areas makes it difficult for these trees to grow again – leaving the Helmeted Honeyeaters with limited options to build their nests. Stiff competition from Bell Miner Honeyeaters is also a problem as well as its vulnerability to predators around.
