“The Kestrel or Sparrow Hawk is about the size of a Robin, and is the only small hawk which has a shade of chestnut-red in its tail feathers. Reed truly says that it has ‘bright colors and odd markings.’ It is so handsome and at the same time so evidently harmless, that it has escaped much of the destruction aimed at its larger companions. Another point in its favor is its ability to adapt itself to its environment: it is equally at home in the pasture lands of the east and the forests of other regions.
“The Kestrel feeds principally on mice, large insects, frogs, and snakes. At times it attacks birds and may kill jays, quail, and other birds as large as itself. It may visit towns where sparrows abound, whence the name ‘Sparrow-hawk.’ Dr. Taverner, however, thinks that a more appropriate name would be “Grasshopper Hawk.” (And he notes that when taken from the nest young, this little falcon is easily tamed.) Scientists have examined 291 stomachs and found that birds were killed and eaten only in the winter when insects are not available. “It is obvious that the Sparrow Hawk is beneficial and should be protected.”
