 194:, Colaptes auratus x cafer. Hybrid Flicker. 



Though most of the notorious hybrids between the eastern Yellow- 

 shafted and western Red-shafted Flickers are confined to the region 

 west of the Mississippi river, a few are to be found in the east, and 

 four specimens at least have been taken in eastern Pennsylvania. 



On October 1, 1889, Mr. I. N. DeHaven shot two Flickers near 

 Conshohocken, Pa., which had the wings and tail bright reddish 

 orange ; unfortunately only a few of the feathers of these speci- 

 mens were preserved. Another specimen, which is in Mr. De- 

 Haven's collection, secured May 1, 1892, at Peach Bottom, Lancaster 

 county, Pa., has a few red feathers in the moustachial stripe, and a 

 similar specimen was shot near Philadelphia, April 13, 1886, by Mr. 

 Herbert Brown (^No. U6, Coll. W. Stone). 



Three or four other specimens with a few red moustachial feathers 

 were shot by Mr. T. M. Trippe at Orange, N. J. (Amer. Nat., 1873, 

 p. 498).
