Grey-streaked Honey-eater is a Papuan mountain endemic, which occupies a broad variety of habitats and is found at different altitudes. We saw these birds at the lower altitudes of about 2000 metres above sea-level, mostly in the forest interior or at the forest edge. On the higher altitudes around the lake (above 3300 metres), the birds occur in alpine dwarf shrub and dwarf forest.
The bird on the picture came to this tree, to drink sap form the tree. Apperently this tree seemed to secrete a kind of fluid on a spot where the bark had been loosened (by birds?). Belford's Melidectes as well as Grey-streaked Honeyeater were frequent visitor's to this particular spot on the tree. After I accidently discovered this, I sat a few hours hidden between the vegetation, close to the spot and waited for the birds to come to drink.
