The ready adoption by our local birds of the newly imported species 
mentioned (Melia Azedarach, Phaseolus vulgaris, Prunus Persica, Eucalyptus 
jicifolia, Callistemon lanceolatus, Catalpa bignonioides, Salvia splendens, Gre- 
villea robusta, G. Danksii, and Manihot Glaziovii, not to mention Canna 
indica and Musa sapientum) would seem to show that nectar-eating birds 
must experiment freely on any new flowers that they may come across. 
M. SUMMARY OF MAIN POINTS. 
1. Not only mainly ornithophilous flowers, but a number of essentially 
entomophilous flowers were visited by sunbirds. 
2. Not only sunbirds (which indeed are often great evaders of the natural 
opening) but many other birds as well visited certain flowers freely for their 
honey and were probably of use to them for cross-fertilization. 
3. Certain birds, and some individuals more than others, apparently dis- 
liked something in connection with the natural opening—possibly the being 
besprinkled with pollen—and tended always to enter flowers by breaches 
made by themselves or their predecessors. 
4. The plant’s liability to such breaching depended primarily on whether 
it came within the “ beat,” for the time being, of a destructive individual or 
flock. 
5. Other birds tended, contrariwise, to enter the flowers by their natural
