|In the family of "goatsuckers", I first starting seeing these small birds hunkered down on the ground at night at the Dipper Ranch after we put a thick layer of gravel on the driveway.|
Those night critters.
|Little owl at the Newt Spring on September 14th.|
|No 'ears' on this owl. September 14th owl again.|
|Small owl standing on a small post in the corner of the Newt Springbox on August 18th. Probably a northern saw-whet owl.|
|I would definitely describe this owl as "shockingly huge" thus a great-horned owl. At the Newt Spring in June.|
When Paul Noble censused owls at the nearby Monte Bello Open Space Preserve in 1986 and 1987, he found the different species of owls associated with vegetation types as a percentage of the total times observed/heard like this:
Northern saw-whet owl -
Broadleaf evergreen forest 4%, riparian 16%, meadow 0%, Douglas-fir forest 80%.
Northern pygmy owl -
Broadleaf evergreen forest 5%, riparian 30%, meadow 0%, Douglas-fir forest 65%.
Western screech owl -
Broadleaf evergreen forest 98%, riparian 0%, meadow 0%, Douglas fir forest 2%.
Great-horned owl -
Broadleaf evergreen forest 31%, riparian 0%, meadow 25%, Douglas fir forest 39%, chaparral 5%.
The Newt Springbox is covered by a narrow band of large oaks and California bays (=broadleaf evergreen forest) surrounded by grassland. I don't remember any Douglas firs at this location. But as a water source, it could be considered riparian-like. The fence post that the western screech owl/great-horned owl was on in Caught Me Singing at the Gate was along the gravel driveway that has a large grassland on the downhill side and a few large canyon oaks on the uphill side.
|Barn owl in August.|
|Nest box built into the barn for the barn owls.|
|A goatsucker, probably a common poorwill, on the driveway on April 29, 2011.|
|Tentatively identified as common poorwill on the night before Halloween. This view gets a little more of the top of the head.|
You will probably see some night critters today. I hope they are friendly.
