DESCRIPTION OF NESTS AND EGGS. 
. Nests, placed in holes of trees, either natural cavities or the deserted holes of Woodpeckers; but little or no material is 
used in constructing the nest. 
Eggs, four to six in number, rather spherical or broadly oval in form, ashy-white or reddish in color, spotted, dotted, 
and blotched, with reddish-brown, dark-chocolate, and occasionally with lilac, frequently so thickly as to obscure the 
ground color. Dimensions from l - 00x 1’25 to 1'05 x 1*35. 
HABITS. 
Although the little Sparrow Hawks are quite common almost anywhere in Pennsyl¬ 
vania and southward, I never found a locality where they were so abundant as about Mia¬ 
mi in Southern Florida. They perfectly swarm here; in fact, it is not uncommon to see' 
twenty pairs in an hour’s walk. In the North, they are very shy; indeed it was difficult to 
procure specimens at Jacksonville; but at Miami, I was quite surprised to find them as un¬ 
suspicious as any of the small birds, for they would permit me to walk directly under them 
as they sat on the low limb of a pine, not more than twenty feet above my head. This 
tameness is, probably, largely due to the fact that, previous to my visit, they had never 
been hunted but I could not help thinking that they were affected the by enervating climate 
in which they lived. It is true, they had the s^rae abrupt, rattling cry, so characteristic 
of this species every-where, but this was given with less vim, the birds exhibiting but little 
excitement when uttering it, as they usually sat on a branch, only occasionally jerking their 
tails. Even this latter named movement, so noticeable in members of this species, was 
seldom made; in fact, much of the almost startling energy usually displayed by the Spar¬ 
row Hawks in the North, appears to have nearly deserted these inhabitants of the Sunny 
South. 
After all, the change in the birds is but comparative and the difference is not strick- 
iiig, for everything, in the almost perfect climate about Miami, is in keeping with quie¬ 
tude and repose. Then, too, the Sparrow Hawks of Southern Florida, gain a livelihood 
quite easily, for grasshoppers which form the greater part of their food, are very abundant 
thoughout the year; so numerous, in short, that a Hawk may live, and live, well, all its life 
in an area of a few square rods, and it is extremely probable that many individuals pass 
their entire lives within sight of the tree in which they were hatched. 
Thus the history of a particular pair of Sparrow Hawks of Miami, is easily written. 
When the first rays of the morning sun touches the tops of the huge, weather-beaten pine 
that has greeted his appearance many thousand times, the happy pair awake, stretch them¬ 
selves, give a cry or two, and take their breakfast of grasshoppers; they lunch lightly on 
the same insects, arrange their feathers at their leisure, then watch the flocks of Warblers,
