an outer and an inner depth of 2.50 and 1.50 

 inches. 



The eggs are five in number, dull white, and 

 spotted with slightly yellowish-rufous markings, 

 which are more plentiful about the larger ex- 

 treniity. They measure .95 of an inch in length 

 and .65 in width. The above description of nest 

 and eggs is substantially taken from the work on 

 "North America Birds." 



Passercuhis savanna, Bonap. 



;.. The. Savanna Sparrow is principally a maritime 

 species,, and . only occasionally found inland. In 

 Eastern Pennsylvania it is by no means common, 

 and is found mainly in lowlands of a hurnid char- 

 acter. It ordinarily visits this latitude from the 

 ist to the i55h of April, and after a stay from a 

 -week: to ten days, retires north to breed. In 

 habits ' it is pre-eminently terrestrial. We have 

 seldom, oSserved it on a bush, or tree, or even a 

 fence-rail. 



It is far from being shy, and can be approached 

 without difficulty. In some parts of the country 

 these birds are quite gregarious, and move in 

 large Hocks and associate with other species, which 

 is particularly the case about Columbia, South 

 Carolina where they winter from October to April, 

 according to Dr. Coues. During their short stay 

 .with us in .April, we have generally observed soli- 

 tary individuals, very seldom as many as two or 

 three together..
