Lanius borealis Vieill. 
1Three species of shrikes have been recognized in New York state, but the status of 
the forms is not well understood, it often being a matter of difficulty to assign indiyidual 
specimens to their proper species. William Palmer, after an examination of 176 speci- 
mens, proposes to ‘‘ relegate excubitorides to the plains region west of the immediate 
Mississippi wooded drainage area, ludovicianus to the south Atlantic and gulf coasts, 
and Florida, and to recognize a new form (L. I. migrans) as occupying much of the 
remaining region of the east.’’ The acceptance of his views has been deferred by the 
American ornithologists union for lack of material, and so it seems best for the 
present to let the species stand as follows. See Auk, 15:244-58; also 16:133.
