ANDERSON — THE BIRDS OF IOWA. 361 



trees along streams. The bird's name is derived from the ashy 

 veiHng of the black feathers on throat and breast, which suggests 

 the appearance of crape. 



County records: Blackhawk — "migrant; late in season" (Peck). 

 Hancock — Shot male May 22, 1897 (Anderson). Jackson — "com- 

 mon transient" (Giddings). Johnson — migrant; not rare; male 

 found dead on University campus, May 29, 1903; shot male May 

 II, 1905 (Anderson). I^inn — "taken here in spring of 1896" 

 (Kej-es); "a specimen in my collection taken June 4, 1901 " 

 (Berry); "migrant" (Bailey). Lee — " scarce migrant " (Praeger, 

 Currier). Scott — "rare migrant; seen only in spring, May 14-22" 

 (Wilson). Winnebago — saw one August 28, 1901, at Forest City 

 (Anderson). Winneshiek — "rare migrant; reported by Hall 

 Thomas" (Smith). Van Buren — "spring and fall migrant; tol-

 Yellow-throat. 



The Iowa records of Yellow-throats have been variously refer- 

 red to G. trichas (Maryland Yellow-throat) and G. t. occidentalis 

 (Western Yellow-throat), but from the range of this new varietj' 

 — "northeastern U. S. and southeastern British Provinces .... 

 westward to northern Ontario, Mich., Wis., Minn., and eastern 

 North Dakota, and southward through Mississippi Valley to up- 

 land districts of the Gulf States" (Ridgway, Birds N. and Mid. 

 Amer., ii, p. 665) — it is apparent that all Iowa records should be 

 referred to this subspecies. The Northern Yellow-throat is a 

 common or abundant summer resident in all portions of the state, 

 arriving in the early part of May and remaining until the latter 

 part of September. While it is most common near grassy sloughs 

 and along willow-growni creek banks, it is often seen in hedges 

 along roadsides or gardens. The species is readily identified by 

 its bright yellow throat and black mask along forehead and sides 

 of cheeks. The nest is placed near the ground in clumps of grass 

 or low bushes. On July 7, 1893, I found a nest containing two 

 Yellow-throat's and two Cowbird's eggs, in a clump of weeds and 

 wild willow shoots, about fifteen inches from the ground; and 

 July 14, 1893, a slightly incubated set of three eggs in tall saw- 

 grass in a nearly i\xy slough, about four inches above the ground.
