6 The \\'ii.son Bulletix — Xo. 102 



Length, 299 mm.; wing, 154 mm.; tail, 87.5 mm.; exposed ciil- 

 men, 58 mm.; tarsus, 10 mm. 



16. Dryobates iJubcsceus mcdianus (Swainson). — Downy Wood- 



pecker. 



On May 31 a pair of these woodpeckers was taken in a small can- 

 yon near Leal, and with them a single young male, recently out 

 of the nest. All were working about in the branches of a cotton- 

 wood. The two adult birds have the following measurements: 



No. 1183 (Coll. A. W.) ad. c^, wing 92 mm., tail 52 mm. 



No. 1197 (Coll. A. W.) ad. $, wing 93 mm., tail 53 mm. 



These two birds, while intermediate in measurements between 

 pubescens and niedianus are nearer the latter form. The under- 

 parts are much stained, but the color is that of medianus. The 

 breast and abdomen are clearer white than in specimens of D. p. 

 pubescens from Christ Church Parish, South Carolina, and from 

 Florida, examined in the United States National Museum. The im- 

 mature bird is in juvenal plumage, with the black of the upper- 

 parts tinged with slate and the feathers of occiput and crown tipped 

 with red. The nuchal band is barely indicated. 



17. Melanerpes erythrocephalus (Linnaeus). — Red-headed Wood- 



pecker. 

 Red-heads were tolerably common about scattered groves of trees 

 on the prairie and were seen in the town of Minco. 



18. Centnrus carolimts (Linnaeus). — Red-bellied Woodpecker. 



A few Red-bellied Woodpeckers were found in small groves near 

 Minco (recorded here on May 24). On May 31 several were found 

 in the wooded canyons west of town. 



19. Colaptes cafcr collaris Vigors. — Red-shafted Flicker. 

 Flickers were rare at this season. Only two were seen, one May 



26 and another May 31. 



20. CliordcUes virginianus hoKelli Oberholser. — Howell's Night- 



hawk. 



This is the breeding form of Nighthawk in the region around 

 Minco. It. is represented by skins of eight males taken May 24, 

 26 and 31 and a female secured on May 31. Three of the birds 

 taken (Coll. A. W. Nos. 1132, 1186, and 1188) are grayer and have 

 less ochraceous in the pale markings of the dorsal region than typ- 

 ical C. V. hoicelli, in this verging toward sennetti. However, all 

 three have the ground color of the upper parts dark with a more 

 brownish cast than is found in sennetti and I consider them merely 

 pale individuals of C. r. houclli. All of the other skins are typical 

 of this form. 



Nighthawks were abundant during the period that I collected at 

 Minco and were seen daily. Many were found perched on drift
