434 Ferry, Notes from Southern Illinois. [b'V. 



49. Lanius ludovicianus migrans. Migrant Shrike. — Several Shrikes 

 seen at Mound City and Olive Branch are tentatively referred to this 

 species. 



60. Vireo olivaceus. Red-eyed Vireo. — Common. Moulting and 

 mostly immature birds. 



61. Vireo noveboracensis. White-eyed Vireo. — The most character- 

 istic bird of the thickets bordering the woods. It has a very pleasing and 

 unique song. It is a rolling trill, with a flute-like quality. While listen- 

 ing to the song I wrote it thus: Twe-wa-ra, ra-re-ra. 



02. Mniotilta varia. Black and White Warbler. — Common. Both 

 adult and immature birds taken. They were found in deep woods. 



03. Protonotaria citrea. Prothonotary Warbler. — Abundant. All 

 young birds had the fully adult plumage. 



04. Compsothlypis americana ramalinse. Western Parula Warbler. 

 — These birds were tolerably common at Mound City. They kept to the 

 tree tops in the river bottoms and in company with Cerulean Warblers. 

 Three specimens, including immature as well as a fully plumaged adult, 

 are typical of this subspecies. I believe that a considerable portion of 

 the small flitting forms high up in the trees were of this species. Sev- 

 eral times the faint, insect-like trill za-ze-za, zee-zee of this bird was heard. 



05. Dendroica aestiva. Yelloav Warbler. — Two young birds seen 

 at Olive Branch on the 11th. 



00. Dendroica cserulea. Cerulean Warbler. — One taken at Olive 

 Branch in dense timber. It was abundant in the Cottonwood and willow 

 bottoms along the Ohio at Mound City. Small bands of them were found 

 flitting about the tree tops, betraying their presence with their faint 

 lisping notes, or by occasional snatches of their song. The latter may be 

 represented thus: whee-ta-te, zee-ee-e-e-e. 



07. Seiurus motacilla. Louisiana Water-Thrush. — Two seen at 

 Olive Branch. One taken. 



08. Oporornis formosa. Kentucky Warbler. — One taken at Olive 

 Branch, 3 at Mound City. Two were taken at one shot at the latter place. 

 The adult was feeding the immature bird, though the offspring was as 

 large as the parent. 



09. Geothlypis trichas brachidactyla. — Northern Yellow-throat. — 

 These birds were everywhere profusely abundant and their sharp 'chip/ 

 sounded from nearly every thicket and weed patch. Very few adult 

 males were seen and most of the birds taken were moulting. 



70. Icteria virens. Yellow-breasted Chat. — These shy birds were 

 tolerably common at Olive Branch and 3 were seen at Mound City. They 

 inhabited the densest thickets. 



71. Wilsonia mitrata. Hooded Warbler. — One taken along Cache 

 Creek, near Mound City. 



72. Setophaga ruticilla. Redstart. — Tolerably common. Only 3 

 adult males were seen, the rest were immature or females. 



73. Mimus polyglottos. Mockingbird. — Abundant at Grand Chain, 

 but inexplicably absent from other localities visited.
