186. Certhia familiaris americana. Brown Creeper. A com- 

 mon winter resident from October 5 to April 30. It is most abun- 

 dant in October and April. 



187. Sitta carolinensis caroUncnsis. White-breasted Nuthatch. 

 A common permanent resident. The writer never saw the nest but 

 during his stay on Mormons Ridge, from June 28 to July 2, found 

 young birds still showing nestling down to be very common. They 

 had evidently been hatched nearby. 



188. Sitta canadensis. Red-breasted Nuthatch. An uncommon 

 migrant. I have the following records: March 31, 1913, one in 

 the Soldiers' Home grounds ; April 6, two birds seen on the Coun- 

 try Club grounds; May 1, 1913, a single bird at the Country Club; 

 a single bird November 18, 1913, in the Marshalltown cemetery; 

 and on April 12, 1914, two in the City park. 



189. Bccolophus hicolor. Tufted Titmouse. This species seemed 

 to be a rare permanent resident, at least the records are well scat- 

 tered throughout the year. I have no evidence of its breeding. The 

 records are as follows: April 5 and 12, 1913, a pair seen at the 

 Country Club ; January 25, 1914, two taken from a little clump of 

 willows along the river (Wilson Bui., Vol. XXVI, p. 104) ; Septem- 

 ber 18, 1914, a single bird seen near the Goose ponds, and Febru- 

 ary 28, 1915, a pair in the Soldiers' Home grounds. 



190. Penthestes atricapillus atricapillus. Chickadee. An abun- 

 dant permanent resident. A pair was noted feeding young on May 

 30, 1914, and a brood of six young were found May 22, 1915. 



191. Rcgulns satrapa satrapa. Golden-crowned Kinglet. The 

 golden-crowned kinglet was an abundant spring migrant from April 

 6 to April 17. Each year they were abundant on one day and 

 scarcely seen at any other time. April 6, 1913, the trees were full 

 of them, but they were not seen on any other date ; the same was 

 true in 1915, the date of their appearance being April 8. In 1914 a 

 single bird was seen on April 9, one on April 11. and two on April 

 12. The great flight came on April 17 after which they were not 

 seen again. In the fall they appeared from September 22 to No- 

 vember 24 in 1913, but were not noted at all in 1914. 



192. Reguliis calendula calendula. Ruby-crowned Kinglet. An 

 abundant migrant from April 3 to May 17 and September 9 to Octo- 

 ber 27. It was much more common than R. satrapa in both spring 

 and fall migrations. 



193. Hylocichla mustelina. Wood Thrush. A common summer 

 resident from May 2 to October 2. One pair were watched building 

 on May 19, 1914. The female was incubating on this nest on May
