. The birds of California : a complete, scientific and popular account of the 580 species and subspecies of birds found in the state. Birds; Birds. The American Kestrel. in Riverside C A DETERMINED INVESTIGATION sharp-spurred claws, and tree-tops serve for sentry boxes whenever the birds pass that way. Telegraph poles are regarded as a special con- venience, since they traverse the treeless stretches which afford no other watch-tower; but fence-posts will suffice in default of more elevated stations. From such points of vantage as these the birds attentively watch the happenings on the ground, and dive down whenever they consider that their presence is needed by mouse or grasshopper. The Falcon trusts, so far as his prey is concerned, to his elevated position, and does not hesitate to glance freely from side to side; while the wayfarer is regarded as likely as not with a frank curiosity not unmingled with friendliness. Much time is spent, also, upon the wing, not circling after the manner of Accipiters and Buteos, but in passing rapidly over the scene, or else flying slowly but directly over such promising areas as grassy meadows and fallow fields. Now and again the bird checks itself suddenly and pauses at a good height to study a suspicious movement in the grass below. It will thus flutter over one spot for a minute at a time, and then pass on disappointed, or else pounce suddenly upon its prey and bear it off to 1638.
