PLATE XLIII. 
Corvus corax, . : : Pennant. Monraer. 
NipiFICATION commences early, even in the coldest 
climates: here sometimes so soon as January, and the eggs 
have been taken in the middle of February. Incu- 
bation lasts about twenty days: the male and female both 
sit, and the former feeds and attends upon the laiter. 
The nest, which is large, and composed of sticks, 
cemented together with mud, and lined with roots, wool, 
fur, and such materials, is placed in various situations 
—in the clefts of the branches of tall trees, church 
towers, caves, cliffs, and precipices. The mausoleum in 
the park of Castle Howard, the seat of Lord Carlisle, 
in Yorkshire, is still resorted to for that purpose. 
The eggs are four, five, six, or seven in number, of 
a bluish green colour, blotted with stains of a darker 
shade, or brown: they vary much in shape. 
One varicty is pale grey, slightly dotted with a few 
distinct dots and marks. 
A second is light green, with a few dashes and 
many small marks of a darker hue. 
A third, pale greenish grey, marked thickly all over 
with small marks. 
A fourth is dull pale olive green, with oblong marks 
and dots all over.
