We have Honeyeaters here too. I've seen them hover like yours at times but that's not their usual way. Our biggest ones - Red wattle birds are falling about in our Eucalypts at the moment. There's always a type of Gum tree flowering. These are big bossy birds that sound as though they are coughing. Little New Holland Honeyeaters are more furtive. They hide in the Banksia bushes pretending to be flower cones.
I remember visiting New Mexico and seeing big moths that looked just like Humming birds. Amazing creatures. Joy
