BIRDS OP NORTH AND MIDDLE AMERICA 177 



Lake and Curlew in Ferry County, Wash. Apparently there is here 

 represented a well-marked "ecological race" which shows a greater re- 

 semblance to incana than anything else and yet completely cut off from 

 that form by ajjhiis and phaia. This may be a case of morphological and 

 ecological parallelism, since in central northern Washington the prairie 

 grassland merges with the montane forest in muck the same way that it 

 does in Utah and Wyoming, where typical incana occurs. Since the 

 variation seems not to have a geographical range distinct from affinis, it 

 is not here given a subspecific name. A more thorough study of the 

 problem in the field, however, might show such recognition to be desirable 

 on the basis of ecological segregation of the type mentioned by Miller 

 (Amer. Midi. Nat., Ixxvi, 1942, 34) in certain species of the San Fran- 

 cisco Bay region.
