38. Phloeotomus pileatus pileatus. Pileated Woodpecker. — In 



the larger forested areas of the river bottoms, a fah'ly common resident. 



39. Melanerpes erythrocephalus. Red-headed Woodpecker. — 

 A winter resident and one of the rarest Woodpeckers. A party of eleven 

 flew over town September 12, evidently in migration, and two more passed 

 by September 18, flying at a great height. A very few were present all 

 winter in the timber along the Blue. 



40. Centurus carolinus. Red-bellied Woodpecker. — Resident 

 and the most abundant Woodpecker near Caddo; some 50-60 were seen 

 November 29 in a three-mile walk along the Blue River. 



41. Colaptes auratus auratus. Flicker. — None were seen until 

 migrants began to appear September 18, but it does not follow that the 

 species could not have been found earlier had the heavy timber been visited. 

 No more migrants seen until October 14 when thej^ became common. 

 Through the winter along the Blue they were next to the Red-bellied in 

 numbers, being most common the last of November and less than half as 

 common in the middle of the winter. They were stiU present in fair 

 numbers March 15, but by March 25 had nearly all departed. 



42. Colaptes cafer collaris. Red-shafted Flicker. — A fine male 

 was collected January 11, being the first one seen. None of the local 

 hunters to whom it was shown had ever before seen a Flicker with red 

 wings, so it evidently is an uncommon visitant to the district. The next 

 day it was found fairly common near the Blue and when this form and 

 auratus were heard calling alternately as happened several times during 

 the day, the note of collaris was so much coarser, rougher, and heavier as to 

 be instantly distinguishable. The so-called hybridus was also noted at the 

 same time and place and both forms remained common the rest of the 

 winter. 



Thus at Caddo, auratus arrived early in the fall and was a common 

 winter resident; few, if any, bred there. After auratus had practically 

 completed its fall migration and settled down to winter numbers, collaris 

 and hybridus came in together, and during the coldest weather all three 

 were found in about equal numbers in heavy timberland, though collaris 

 was perhaps the most abundant. All three forms were still present March 

 15, but collaris and hybridus left a few days later. 



43. Chordeiles virginianus subsp.? Nighthawk. — A few were 

 already present the first of September but whether or not they were summer 

 residents could not be told. By September 9 southward migration was 

 well started; an increase was noticeable September 18 when they were 

 most common. Their numbers slowly decreased and the last was seen 

 October 10. 



44. Archilochus colubris. Rubry-throated Hummingbird. — Seen 

 only twice, one bird each day, October 7 and 8. 



45. Muscivora forficata. Sclssor-tailed Flycatcher. — A com- 

 mon breeder, scattered over much of the country; gathering in flocks 

 September 11; moving southward in the early evening September 14; the
