This little owl is not only inoffensive, but useful to the farmer, in clearing his neighbor¬ 
hood of mice and other noxious vermin. It is, I believe, a species exclusively belonging to 
the Union, and not found beyond its limits. The adult and young of this species have, from 
the time of Pennant, been considered as distinct, until they were separated by the Prince of 
Canino in the Transactions of the Academy of Natural Sciences, and afterwards in the 
Annals of the Lyceum of New-York. A similar error for a long time prevailed in Europe in 
relation to the Syrnium aluco. A writer in the Transactions of the Academy of Sciences of 
Philadelphia, Vol 8, p. 53, asserts, however, that the color of both young and old is variable 
and uncertain, or else that they are specifically distinct. He arrives at this conclusion, from 
having observed the old and young of the Mottled Grey Owl, neither of which had the 
slightest shade of red about them. 
The Little Screech Owl, or Red Owl, selects the hollow trunk of a tree for its nest, near 
outhouses : it lays 3-4 white rounded eggs. The nestlings are yellowish white. It feeds 
on mice and insects, and is gentle and inoffensive.
