color in their temporary associates. In some places decoys repre- 

 senting only the rear parts of ducks are used, and these ever- 

 dipping counterfeits which never show a head, nevertheless fill 

 the bill; in other localities the bottom in shallow water is simply 

 turned up in spadefuls, making dark lumps and ducks decoy to 

 these. Mr. White tells me that the best day's shooting at black 

 ducks he ever enjoyed was begun with his shoes as decoys, dead 

 ducks being substituted as they were killed. These things prove 

 that on some occasions at least some of the most typically flocking 

 birds do not pay any attention whatsoever to markings directive 

 or otherwise. 



AN APPARENTLY UNRECOGNIZED RACE OF THE RED- 

 SHOULDERED HAWK. 



BY LOUIS B. BISHOP, M. D. 



Buteo lineatus texanus subsp. nov. 

 Texas Red-shouldered Hawk. 



Type.— 9 adult, No. 22355, Coll. of Louis B. Bishop; Corpus Christie 

 Texas, Nov. 7, 1909; John M. Priour. 



SuBSPECiFic Characters. — Similar to Buteo lineatus elegans, but 

 breast usually more spotted with buffy, the dark shaft lines of chest 

 more conspicuous and the head and back more rufous. 



Measurement OP Type. — ^Wing, 12.98; tail, 8.62; culmen, .90; tarsus, 

 3.23 inches. 



Sixteen adult Red-shouldered Hawks, collected for me at Corpus 

 Christi and Brownsville, Texas, in October and November, 1909, 

 by Mr. Frank B. Armstrong and John M. Priour, closely resemble 

 each other and differ as described above from the only adult B. I. 

 elegans I have been able to examine. They are also much larger 

 than this bird — an adult spring male from California — but not 

 above the measurements given for this race. 



These Texas birds are much more richly colored below than fall
