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.

Black and Yellow Warbler.

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.

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-
