Bird Migration in the Mississippi Valley. 37 



among them, seen on February 22. March 11. Still the same at this date, and 

 on March 13 a newly-arrived female was seen, and on April 4 and 5, an old 

 bird in high plumage. Jefferson. Summer sojourner. On April 4 first saw 

 one flock of fifteen to twenty males and females ; very active, mating, and 

 a few in pairs. April 12. The flock seems to have passed on, as I found only 

 one left. No more flocks seen during the Spring, but single ones and pairs 

 seen every few days. 



Pileated Woodpecker (H. pileatus). St. Louis. Resident. Seen on May 22. 

 Jefferson.- Not seen. 



Red-bellied Woodpecker (G. carolmus). St. Louis. -Summer, and I think 

 also Winter, sojourner. On February 22 first saw two pairs, which were very 

 much excited and noisy at breeding stands. Jefferson. Probably seen, but 

 not certainly identified. 



Red-headed Woodpecker (M, erythroceplialus). St. Louis. Summer resi- 

 dent. Remained through the Winter ; two single birds and one pair seen in 

 a week. On February 22 they were in the same numbers. On April 12 

 many were found in heavy timber, but not generally distributed. May 1. 

 Evident increase during the last few days. Jefferson. Summer sojourner. 

 On May 6 five males came in the afternoon, and during the following night 

 about fifteen per cent came. May l'2.~- Almost the height of the season. 



Yellow-shafted Flicker (C. auratus). St. Louis. Summer resident. Re- 

 mained through the Winter; two set n in one week. On March 14 several 

 were here in company with robins and blackbirds. The bulk of the species 

 was here on April 4, and from the 4th to the 8th was the height of transients. 

 Jefferson. Summer sojourner. First saw one on April 8, and next day three 

 more. On April 9 there were a few more, and on the 10th they were heard 

 every few minutes. On April 11 there was no increase, but the 21st brought 

 us a flock of seven. 



Belted Kingfisher (C. alcyon). St. Louis. Summer sojourner. First seen 

 on April 6, and by the 14th they were nest digging. Jefferson. Summer so- 

 journer. First saw one on April 4, and on the llth two birds, seen for the 

 third time. 



Yellow-billed Cuckoo (G. americanus). St. Louis. Summer sojourner. First 

 one noticed on May 16. Jefferson. Summer sojourner. This and the next 

 were undoubtedly seen about May 21, but not close enough to distinguish 

 them. 



Black-billed Cuckoo (C. erythropJitlialmus). St. Louis Summer sojourner. 

 First seen on May 2.
