Eastern Spinebills consume nectar and insects equally, but during autumn and winter when the availability of insects is diminished they rely largely on nectar.
Their energy demands are significant and they need to forage almost continuously if nectar supplies are low. Some birds have been recorded spending up to 65% of their time meeting their requirements in these circumstances. We have a flowering Yellow Gum in our front yard, the ornamental variety Eucalyptus leucoxlyon ‘Rosea’, which is a smaller pink-flowered version of our local species. This plant regularly boasts a good supply of flowers – it’s a favourite haunt for visiting spinebills.
