190 BIRDS OF OHIO. 



eastern half of the state. There are three probable records 

 of its occurrence in Lorain county.* In the rougher parts of 

 the state this warbler is to be found in the gorges well 

 grown with brush and trees. It seems partial to the S'teep 

 hillsides in such localities. 



The first appear in southern Ohio during late April or 

 early May, and return south late in September. 



266. (678.) GEOTHLYPIS AGILIS (Wils.). 57. 



Connecticut Warbler. 



Synonyms: Oporornis agilis, Sylvia agilis, Trichas agilis. 

 Kirtland, Ohio Geol. Surv., 1838, 162, 182. 



This is one of the rare warblers which pass entirely across 

 the state. Dr. Wheaton recorded five specimens taken in the 

 state. The unquestionable records since 1882 are hardly 

 more. But three have been recorded for Lorain county, one 

 of them May 24, 1902. It must be looked for on or near 

 the ground in brushy places, but not necessarily where it 

 is wet. The birds are timid and retiring, but may be closely 

 approached with care. I have never heard the song to know 

 it. 



The migrations appear to occur rather late in spring, and 

 the return in fall is during the early part of August. 



267. (679.) GEOTHLYPIS PHILADELPHIA (Wils.). 59. 



Mourning Warbler. 



Synonyms: Sylvia Philadelphia. 



Philadelphia Warbler, Black-throated Ground Warbler. 

 Wheaton, Ohio Agri. Report, 1860, 363, 373. 



While this species seems to be more numerous than the 

 last, it is by no means common anywhere in the state. It 

 does not remain to breed, but passes north of our border. 

 During their migrations these birds are to be found on or 

 near the ground, rarely mounting into the lower branches 

 of the trees. They seem to prefer brushy tangles within

 Oberlio by the writer.
