180 BIRDS OF OHIO. 



middle of April, depending on the weather at that time, and 

 tarries until the middle of May, or later sometimes. It re- 

 turns late in September and is fairly common until the 20th 

 of October, scattering individuals remaining into the first 

 week of November. 



250. (657.) DENDROICA MACULOSA (Gmel.). 42. 



Magnolia Warbler. 



Synonyms: Dendrceca maculosa, Sylvia magnolia, S. maculosa, 



Sylvicola maculosa, Motacilla maculosa. 

 Black and Yellow Warbler. 

 Wilson, Am. Orn., Ill, 1811, 63. 



Dr. Wheaton says of this species, "Abundant and regular 

 spring and fall migrant in middle Ohio, summer resident 

 in small numbers in north-eastern Ohio." At the present 

 time it is generally regarded as not common as a migrant, 

 except occasionally, when it becomes common. I find no 

 evidence that this warbler now breeds within the state. 

 While few of us find the first warblers on their return in 

 late July or early August, it is well known that they migrate 

 as early as that. Middle of the summer specimens do not, 

 therefore, indicate that the birds have bred in the vicinity. 

 Late June records would more likely indicate breeding birds. 



The Magnolia Warbler reaches northern Ohio early in 

 May, and the last has passed north about May 21. It re- 

 turns late in July or early in August, judging from the 

 records, and remains until about September 20. 



251. (658.) DENDROICA RARA Wils. 43. 



Cerulean Warbler. 



Synonyms: Dendroaca cserulea, Sylvia azurea, S. rara, Dendroi- 



ca caerulea. 



Azure Warbler, Blue Warbler. 

 Kirtland, Ohio Geol. Surv., 1838, 163, 182. 



Dr. Wheaton's statement, "Abundant summer resident," 

 no longer applies to this woods-haunting warbler. It is uni- 

 versally reported as not common during the summer. It 

 would be hard to assign a reason for this decrease in num-
