Female American Kestrel Falco sparverius

Female American Kestrel, Falco sparverius, at the Tijuana River National Estuarine Research Reserve, resting on barbed wire while scanning the grass below for grasshoppers, lizards and other small prey.  It always amazes me how birds leisurely lounge on  barbed wire without ever apparently getting poked.  I've even seen birds on Chollas cactus (for example, the cactus wren), which is no small feat.
