**Hence**in cases of pairs of species where these broad characteristics are similarin each species, but spectral qualities are quite different, it is useful to return to

the original waveform and perform spectral analysis. The Western Meadowlark

**Hence**if there are x samples of the one bird and y of the other, the number in thetable corresponding to the two birds is the average of xy distances. The 14*14

distances are broken into four tables for printing convenience. Each sample is ...

consecutive EC's, c of them will have length x and (a-c) will have length x+1. If

#=}, the two values will oscillate and all Eclengths will be different from the

preceding.

**Hence**all such sequences have identical distributions of EC lengths. In aconsecutive EC's, c of them will have length x and (a-c) will have length x+1. If

#=}, the two values will oscillate and all Eclengths will be different from the

preceding.
