described is the only one in which I have seen discomfort of this kind shown ; 
also, only certain individual birds trouble always to avoid the proper opening. 
Таш myself inclined to believe that the pollen itself on the plumage, and 
especially round the bill, where it would be harder to clean off, might be in 
itself a sufficient deterrent. Birds, and expecially some individuals, mostly 
male, being very great dandies, are intolerant of foreign matter on their 
plumage, and will go to immense trouble in preening the latter. And pollen 
is, as I have seen, deposited in considerable, and I should have thought 
objectionable, quantities on and in the feathers of such birds as do not avoid 
the natural openings. 
This is, however, merely a theory to account for the actual fact that some 
birds do go to some pains to avoid the natural opening of the flower.
