^°1908^^] Woodruff, Birds of Shannon and Carter Counties, Mo. 205 



On March 19, several (S. p. arenacea were seen in a flock of S. p. pusilla, 

 and I found it easy to distinguish them by the conspicuous gray crown- 

 stripe of tlie former. 



*75. Junco hyemalis. Slate-colored Junco. — Juncos were present 

 in large numbers on my arrival in Carter Co., March 7, and in Shannon 

 Co. March 10. They were less abundant after April 7, and the last were 

 seen April 27, except for a lone male secured May 21 at Grandin, Carter Co.' 

 On examining this latter bird I found that its belly was distended to twice 

 its normal size and was packed solid with a mass of transparent worms, 

 three inches or more long and as thick as a small match, filling up every 

 bit of space in tl\e intestinal cavity. Though able to fly and otherwise 

 in good condition, this load was evidently too much to carry and was the 

 probable explanation of tliis exceptionally late date. 



Dr. Jonathan Dwight, Jr., who is making an exhaustive study of the 

 various races of Juncos of North America, kindly examined the series of 

 thirteen Juncos secured, and di^^ded them into the three races: hyemalis 

 hyemalis, hyemalis connectens, and hyemalis montanus. 



Specimens of J. h. hyemalis, taken from one flock March 11 in Shannon 

 County, were very dark birds and typical of J. h. hyemalis from Alaska. 

 Others taken later in the month and in April were similar to eastern 

 representatives of the race. 



*76. Junco hyemalis connectens. Schufeldt's Junco. — A male 

 Junco collected at Hunter, Carter Co., March 7, and a female collected in 

 Shannon Co. March 17, were assigned by Dr. Dwight to this form. 



*77. Junco montanus. Montana Junco. ^ — A female (No. 1364, $ , 

 Coll. L. B. and E. S. W.), secured March 11 from a large flock of Juncos 

 in Shannon Co. was identified by both Dr. Dwight and Mr. H. C. Oberholser 

 as of this species. 



This is the first Montana Junco to be recorded from Missouri. 



*78. Peucsea aestvalis bachmanii. Bachm an 's Sparrow. ^* — On March 

 19 I saw and secured the first Bachman's Sparrow, and on and after April 

 6 found it common throughout the mixed pine and oak woods of Shannon 

 Co. They seemed to prefer stands of mixed pine and oak to either pure 

 pine or pure oak. 



In Carter Co. I found it only four times (May 17, 24, 27 and June 4), 

 but the fact that almost all the pine had been cut may explain their rarity 

 here. On May 27, in the virgin pine and oak forest near the northern 

 border of the county (Twp. 27, R. 2 East), I flushed a Bachman's Sparrow 

 from a nest containing two of her own eggs and three of the Cowbird — 

 incubation far advanced.^, * This find was the first conclusive proof of
