Fran,
This is known behavior of bluebirds, but most especially of the Mountain
Bluebird, which appear to hunt in the manner of kestrels.

Hello:
I wonder if anyone else has observed this behavior in Western Bluebirds?
While at Deer Creek Center in Selma, Oregon on Saturday, I observed two
Western Bluebird males hovering over a pasture. They had been perched on a
power line over the field, and when they flew down, they hovered, wings
fluttering, much like a kite. The activity was brief, but definite.
(I live in the Hugo area north of Grants Pass. Deer Creek Center is on the
Illinois River Road in Selma, and is home to Siskiyou Field Institute.)
