290. (639). Helminthcros vermivorus (Gmel.). Worm- eating

The Worm-eating Warbler is a rare summer resident in south- 

 ern Iowa, very seldom reaching the central part of the state. I 

 have only one record from northern Iowa, in the Des Moines Val-

 lined with hair-like moss and horse-hairs" (D. L. Savage, 051., 

 X, 12, 1895, p. 352). Mr. Savage took another .set of two eggs,

 "nest with five badly incubated eggs taken June 4, 1904, in quite 

 heavy timber on slightly sloping hillside; male taken" (Binga-

 1889" (Berry); "spring and fall migrant, not plentiful. Collected 

 here by M. E. Peck, spring of 1896" (Keyes). Lee — "rare mi- 

 grant" (Praeger, Currier). Van Buren — "a common bird in Van 

 Buren and Henry counties; I have found their nests in June in
