THE WILSON QUARTERLY. 9 



large boulder, making a most beautiful scene, lighted up by 

 the beams of bright sunlight let in through the tops of the 

 tall pine trees. 



This nest contained two eggs of the Cowbird, one of 

 which was under the lining of the nest, as the birds had 

 re-lined it in order to destroy the Cowbird's egg. But this was 

 in vain, for the scamp deposited a second one when the set 

 was half completed. This set, when complete, contained 

 four eggs of a pure white color with spots of chestnut 

 evenly distributed about the larger end, and not distinctly 

 wreathed as those of the first set. A few blotches were 

 present. The nest was not as well proportioned as the first, 

 but was well made and of a dark color. It was composed of 

 about the sane substance as the other, and oddly enough, a 

 piece of newspaper was conspicuously interwoven as in 

 the other one, though they were found more than three 

 miles apart. These nests were not ornamented at all with 

 lichens, ti s is often reported to be the case. 



The nest of the Blue-headed Vireo measures as follows : 

 Diameter, outside, 3 to 4 inches ; inside. If to 2^ inches. 

 Depth, outside, 2^ to 24 inches ; inside, H inches. The 

 variations in the measurements of the egg are : .71 x. 5(5 

 inches ; .75 x .57 inches ; .73 x .58 inches. 



The Blue-headed Vireo arrives here from the South as 

 early as April 22, and during the migration is to be found 

 abundantly in the woods, but not found as common, if at 

 all, near the houses or about the trees in the streets. They 

 pass northward, and by the last of May become very rare 

 in this locality. They return again in September and 

 linger until October.
