ATHENE CUNICULAEIA, Molina. 
Burrowing Owl.

Figures.— And. B of Am. pi. 432, fig. 2 : Oct. ed. I, pi. 31, (lower figure.) 
Resembling the preceding, but larger ; tarsus longer, and more fully feathered in front to the toes. Varieties of plumage the 
same, but that first described most usually met with and more common than in the preceding. 
Mult — Upper parts light ashy brown, with large spots of dull white enclosed in edgings of brownish black. Throat white ; a 
transverse band of brownish black an'l reddish white feathers across the neck in front, succeeded by a large patch of white. 
Breast light brown, with large spots of white like the upper par's ; abdomen yellowish white, with hastate or crescent-shaped 
spots of reddish brown disposed to firm transverse bands; under tail covert-, tibias, and tarsus, and under wing coverts 
yellowish white ; quills and tail light brown, with spots of reddish white, edged (the spots) with brownish black; tail wi'h 
about six transverse bands or pairs of spots of red ish white, enclosed or edged with dark brown. This is the plumage repre- 
sented in Audubon's plate above cited, and is more commonly met with than the same plumage in the preceding species. It is 
very probably the mature plumage. Another plumage is : Adult? Like that just described, but much lighter, and tinged with 
du 1 yellow, or ochre, having a faded or bleached appearance This plumage is not so frequent as in the preceding species. 
Another plumage is : Younger? Upper parts light greyish brown, with white spots very irregular in shape and confused, and 
frequently predominating on the head. Abdomen nearly unspotted, yellowish white, or with traces only of spots or bands. 
Total length, female, about lflj inches ; wing, 7 to 7j inches ; tail, 3i to 4 inches. Male rather smaller. 
Hub. — North America, west of the Rocky mountains, South America. Spec, in Nat. Mus. Washington and Mus. Acad. 
Philadelphia. 
This owl may be immediately distinguished from the preceding by the more full feathering 
of the tarsus, generally continued without interruption to the toes. The tarsus is also longer, 
and in size the present bird is rather the larger. All these characters are well given in 
Audubon's plate, cited above, though it is not very common to find the present bird with the
