Snowy Owl. 
This owl is a visitor from the northern regions, 
and it only makes its appearance when the 
weather is very cold. Some winters it is very 
scarce, and only one or two specimens can be

Delaware River, and feeds on birds and mice; I

body of a meadow lark. I have had it from Iowa 
as late in the Spring as April, and I supposed it 
to be returning to the North. I have seen it as 
far south as Virginia, along the shores of the 
Accomac; it was plenty in the year of 1875.
