Right you are, Tiaris.
"they feed on nectar, pollen and insects" (Mammals of Australia 3rd Ed., 2008, Van Dyck S and Strahan R (Eds.), pub. Reed New Holland, Sydney). They feed on (and presumably pollinate) the grasstrees (
Xanthorrhoea spp.). They are indeed common, but are rarely seen as they spend most of their time high in the canopy (87% at >15m above the ground, 72% at >20m), feeding on flowering eucalypts.
They are poorly studied, so even though the animal is fairly abundant, specimens would be of significant value to science. Their range includes tall forests and woodlands from Cape York down the whole length of the Great Dividing Range, across the high country and just into SA.
Other curious features include:
- a poorly-understood small, bony disc in front of the ear drum. This is thought to lead to selective sensitivity to very high and very low frequency sound, but it is not clear what advantage that may confer.
- molar teeth with cusps typical of an insectivore, combined with a brush-tipped tongue for nectar harvesting.
- the tail can grip twigs and small branches, as well as assisting in steering and braking.
- like kangaroos and wallabies they can put an early embryo on pause while they are feeding juveniles, so they can make more offspring swiftly should favourable environmental conditions arise/persist ("embryonic diapause"). No other animals share this ability.
I had always wondered what ate the grasstree spikes.....
Anyhoo, just thought I'd share
(ps: Deb, I think I left all of the big words out this time...)
