very local" (Currier); "rare summer resident" (Berry). L,inn — ■ 

 female taken at West lyiberty by Dr. E. H. King, on M2y i, 

 188(1?); recorded by various writers as D. discolor (Anderson). 

 Van Buren — "summer resident; common. I found a nest in the 

 early part of June, 1894, placed in a buckberry bush about three 

 inches above the ground and containing four young only a few 

 days old" (W. G. Savage). Wayne — (A. J. Brown). 



316. (678). Geothlypis agilis {W\\s.). Connecticut Warbler. 



The Connecticut Warbler is a rare migrant in Iowa and has 

 onl}' been reported by a few observers. It is probably the latest of 

 the Warblers to migrate in the spring, having been observed mi- 

 grating during the early part of June. This species has gener- 

 ally been considered as only a spring migrant in the Mississippi 

 Valley and supposed to migrate southward by the Atlantic coast 

 route. Kumlien and Hollister state, however, that they are as 

 common in fall as in spring in Wisconsin (Birds of Wis., 1903, 

 pp. 1 17-18). They are very shy, frequenting dense thickets and 

 shrubbery during migration. 



County records: Lee — "rare visitor. I have no records for the 

 autumnal migration of either this species or p/ii/adr/p/n'a. It is 

 very possible that they return by another route or pass over with- 

 out a stop" (Currier). Linn — "rare and shy; one specimen taken 

 in Linn county and one or two others observed" (Peck); "taken 

 in spring of 1896 by Morton E. Peck" (Keyes). Van Buren — "I 

 have taken a few specimens in Van Buren county; rare" (Wm. 

 Savage, Iowa Orn., i, i, 1894; p. 15); "in 1895 I shot one male. 

 This is the only one I ever observed in our locality" Walter G. 

 Savage). Winnebago- Hancock — Shot a male in my collection 

 May 22, 1897 (Hancock) and female June 4, 1897, at Forest City 

 (Winnebago). A few others were seen in dense thickets, but very 

 shy. The species resembles G. philadcIpJiia closely, but may be 

 distinguished by the whitish orbital ring (Anderson). 



Subgenus Geothlypis Cabanis. 

 317. (679). Gcof/i/ypis p/ii/ade/p/iia (W\\s.). Mourning Warbler. 

 The Mourning Warbler closely resembles the preceding species 

 in appearance and habits, but is rather more common and usually 

 migrates earlier, though it sometimes is found in company with 

 the Connecticut Warbler. It is usually found in thickets or low
