We have an Agavae desmettiana (varigated) in a pot and this year it has sent up a large flower spike and the flowers are starting to open much to the delight of our local honeyeaters.
An Eastern Spinebill demonstrates that you can sip nectar whilst hanging below the flower.
A Lewin Honeyeater finds a more upright position for a sip.
Nectar attracts others as well as honeyeaters and a bee almost got out of shot before the Lewin Honeyeater snared it as a tasty addition to the nectar diet.
