This Jioney-eatcr differs considerably in all its habits from the sun- 

 birds witli. wliicli it is associated. It is generally found in small parties, 

 th3 memhers of which, though acting much, in concert, still maintain 

 their individuality. They follow one another to favourite bushes, 

 chase each other, or feed amicably side by side, and if one is alarmed 

 and flies off, the rest generally follow ; yet they cannot be called 

 gregarious in the strict sense of the word. They are fond of perching 

 on the summit of high bushes, particularly Proteaccva, from the flowers 

 £»f which they extract their food, consisting of insects, and the limpid.
