Eagle in Pomerania, he never found one in a dry forest. The 
only nest which I have seen myself was in Hungary, and was 
situated not more than forty feet from the ground, in a forest 
througli which we proceeded in small shooting parties. The 
bird sat so close that none of the party suspected that the nest 
was tenanted ; and when, after we had been chatting for some 
minutes below the tree, the Eagle suddenly flew off, we were 
so much taken by surprise that she was missed by all three of 
the party. 
Nest. — This is generally a large structure, and Mr. Seebohm 
gives the dimensions of one found by himself in Pomerania as 
four feet long, two and a half feet wide, and two feet high. It 
was very flat, like the nests of all Birds of Prey, the depression 
in the centre not being more than four or five inches. “The 
foundation was composed of sticks nearly an inch thick, but at 
the top they were very slender. The final lining was slender 
beech-twigs with fresh green leaves on them. There was 
also a little down and a feather or two, which had probably 
been accidentally rubbed off the breast of the parent bird.” 
Another nest was lined with fresh green grass. The tree 
selected by the Spotted Eagle is generally a beech, but the 
nest is also found in oak- and fir-trees. 
Eggs. — These are laid early in May, and are generally two in 
number. Sometimes only one is found, and on very rare oc- 
casions a nest has been known to contain three eggs. They 
are very like a small edition of Golden Eagles’ eggs, and are 
alike in shape at both ends, but they are, of course, smaller 
than the eggs of that bird. In those of both forms of Spotted 
Eagle there seems to me to be an occasional tendency for the 
rufous markings to congregate at one end of the egg, which 
is not seen in those of A. chrysaetus. A.xis (in eggs of A. 
pomarina), 2‘3-2-65 ; diam., i-Q-a-i ; axis (in those of A. mam- 
lata), 2 45-2'65 ; diam., I'p-a'r.
