In looking over this list one is impressed with the fact that the
taste of human beings for fruit differs markedly from that of birds.
For example, _Rhus_ seeds are hard and have little pulp to render them
palatable or nutritious. They are usually passed through the
alimentary canal of birds or regurgitated unharmed, and the slight
outer coating alone is digested. In the case of the poisonous species,
this outer coating is a white wax or tallow which appears to be very
nutritious, for these species are eaten much more extensively than the
nonpoisonous ones. The seed itself is rarely broken in the stomach to
get any nutriment it may contain. But in spite of these facts _Rhus_
seeds were found in 49 stomachs, while fruits of huckleberries and
blueberries, which are delicious to the human taste, were found in
only 13 stomachs; and blackberries and raspberries, highly esteemed by
man, were found in only 5 stomachs. Next to _Rhus_ the fruit most
eaten was the dogwood berry, found in 34 stomachs, yet from a human
estimate these berries are distasteful and contain such large seeds
that they afford but very little actual food.
_Summary._--The hermit thrush, as it name indicates, is of solitary
habits and neither seeks human companionship nor molests cultivated
products. It destroys nothing indirectly helpful to man, as beneficial
insects, but aids in the destruction of the myriad hosts of insect
life which at all times threaten vegetation. While it is not easy to
point out any especially useful function of the hermit thrush, it
fills its place in the economy of nature, from which it should not be
removed.
