1S92.I Attwatek, Birds of San Antonio, Texas. 2 ^ CJ 



78. Sphyrapicus varius. Yeli.ow-kkllied Sapsuckkr. — Common 

 migrant. 



79. Melanerpes aurifrons. Golden-fronted Woodimxker. — Com- 

 mon lesident. 



80. Colaptes auratus. Flicker. — Common mi<j;iant and winter resi- 

 dent, but more numerous during ini<;;rations. 



Si. Colaptes cafer. Red-shafted Flicker. — Common migrant. Tyii- 

 ical specimens are rare, but a number of intermediate shades, between 

 cafer and auratus occur, and liave been observed migrating together with 

 typical birds. The bulk of auratus departs before the others. These birds 

 ai-e fond of ants; the crop of one specimen I examined contained hun- 

 dreds of them. 



82. Antrostomus carolinensis. Chuck-will's-widow. — Common 

 summer resident. 



83. Antrostomus vociferus. Whippoorwill. — Rare migrant. 



84. Phalsenoptilus nuttalli. Poorwill. — Common summer resident. 



85. Phalaenoptilus nuttalli nitidus. Frosted Poorwill. -Rare mi- 

 grant. The earliest record of its appenrance in 1891 was March 18. 



86. Chordeiles virginianus henryi. Western Nighthawk. — Abun- 

 dant migrant, and common summer resident. My series of specimens 

 shows three color forms of this species, viz., the red, the intermediate, 

 and the lighter or frosted form. C. texensis probably occurs, but I have 

 not yet been able to add it to my collection 



87. Chaetura pelagica. Chimney Swift. — Rare migrant. 



88. Trochilus colubris. Ruby-throated Hummingbird. — Com- 

 mon migrant. 



89. Trochilus alexandri. Black-chinned Hummingbird. — Com- 

 mon summer resident. 



90. Milvulus forficatus. Scissor-tailed Flycatcher. — Abundant 

 summer resident. 



The regularity with which the summer residents of this locality appear 

 each season is worthy of mention. The state of the weather does not 

 seem to affect these birds in their movements nearly as much as it 

 does those which simply pass through as migrants. During a very dry 

 spring the scarcity of the latter is very noticeable, and not only is their 

 number greatly diminished, but they hurry through on their journey 

 many of them being noticed only for a day or two, while during a wet 

 spring they are much more abundant and stay longer. Particularly 

 is this the case in regard to the Warbler family. The seasons of 1890 

 and 1891 are good examples of the two extremes. Heavy rains during 

 the early spring of 1890 brought the bulk of Warblers, etc., from two to 

 three weeks earlier than in 1891, and from the i6th to the 34th of April 

 was the height of the migration. The corresponding period in 1891 

 (which wa.s an unusually dry season) was from May 12, to May 15. 

 The case of the Hooded Warbler will serve for an illustration. In 1890 

 they first appeared on March 31, were common the next day, and were 

 gone by April 25, while in 1891 they were not noticed at all till May
