90 Vireo belli belli. Bell's Vireo.— A single one collected Septem- 

 ber 8, was the only bird seen in the fall, and it had not yet come in the 



spring by April 4. -r, -nr 



91. Compsothlypis americana usneae. Northern Parula Warb- 

 ler — Was not seen in the fall. The first arrived March 25. 



92 Dendroica coronata. Myrtle Warbler.— The commonest 

 warbler in fall, and the only one that remained throughout the wmter. 

 The first — a single bird — was seen November 16 along a smaU stream. 

 Since the species was found very abundant the first time the heavy tim- 

 ber was visited November 29, it probably arrived in the woods somewhat 

 earlier than it was noted on the prairie. The numbers had decreased 

 decidedly by December 25, but still it remained fairly common all wmter, 

 though constantly lessening in abundance. It began the middle of March 

 to return to the edges of the prairie, whence it had been driven to the bot- 

 tom-land during the winter. 



93. Geothlypis trichas trichas. Maryland Yellow-throat.— 

 Three birds seen in all, two September 9 and one the next day; it had not 

 yet arrived the first of April. . .« r« u- j 



94 Anthus spraguei. Sprague's Pipit.— A flock of 40-50 birds 

 was seen in an open field February 18 in company with Savannah Sparrows, 

 Lapland and Chestnut-coUared Longspurs. The next day none of these 

 except the Savannah Sparrows could be found. 



95. Mimus polyglottos polyglottos. Mockingbird.— A common 

 breeder in town but by the first of September the birds had deserted their 

 nesting sites and most of them must have migrated, for less than half a 

 dozen were seen during the entire winter. The first full song was heard 

 February 21, but the birds had not yet become common by the first of April. 

 96 Toxostoma rufum. Brown Thrasher.— One bird on Septem- 

 ber 8, was the sum total of all seen in the fall. This seems a very early date 

 for it to disappear since at this time it was still present in Minnesota, and 

 it spends the whole winter only a few miles south of Caddo. 



Two silent birds were the first arrivals March 8, which is fully as early as 

 they would be expected to arrive, but no more had been seen to April 7, 

 though by this date the species was far north of St. Louis. Evidently the 

 Brown Thrasher was not a common bird at Caddo. 



It seems a little strange that not a Catbird was seen at Caddo either in 



fall or spring. 



97. Thryothorus ludovicianus ludovicianus. Carolina Wren.— 

 Common resident ; retiring and silent through the winter, but by February 

 23, its full spring song was heard ahnost continually, from various directions 

 and by March 25 it was one of the most conspicuous and noisy inhabitants 



of the woods. 



98. Thryomanes bewicki cryptus. Texas Bewicks Wren.— 



Not noted until November 8, but it may have been present all the fall in 

 the bottomland; by November 25 had become quite common around town 

 and remained so until about December 19. Then its numbers dimmished,
