As is indicated below, we regard the figures of this sample as unreliable to an unknown degree in comparing the relative abundance of one species with another. Accumulation of such data from various localities, however, should prove useful in another type of comparison. Samples of the same species killed in the same way at about the same time at different localities should be directly comparable. Eventually, this should provide us with a means of determining relative abundance of a species in different parts of its migratory route.
