American Kestrel
Falco sparvertius
Oct. 21, 2012

Earlier in the week, while at Jo Hays Vista to watch the fall hawk/eagle migration, I photographed two kestrels interacting with one another.

Normally, kestrels zoom past, darting from side to side, at high speed, making them a challenge to photograph. Consequently, I enjoyed the extended view of the kestrels fighting or playing. Hard to say which, but the extended view was great.

I wish they were closer though. That would have really made my day.

Note in the first photo, the kestrel on the left is flying upside-down.

  Finally, the two kestrels are circling each other back to back.

  The last photo dates back to the end of September, when I had a good view of an incoming kestrel.

  The Latin for American kestrel is Falco sparvertius, which is somewhat closer to its alternative name: sparrow hawk. The kestrel, incidentally, is the smallest North American falcon, no larger and probably smaller than a mourning dove.

Photo note: On October 16, 2012, I used a Pentax K20D, with the Sigma 150-500mm lens, for the first three photos; the fourth was from September 28.
