    It took me years to find night-herons in Clear Lake area, but I now see them a lot. Could it be that the species is increasing its range/population? Any

      Any evidence for an increase?

      The question of the lack of breeding records for Black-crowned Night
      Herons in Mendocino County has puzzled me for a number of years over here on
      the western edge of the county. On 11 May 2005 a fresh juvenile with a
      little clinging down showed up in my Potter Valley yard next to the Red Post
      Vineyard pond. This seems pretty early in the year for it to have dispersed
      very far from the nesting area, and it started me wondering if there could
      be local nesting - perhaps along the Russian River in Potter Valley.
      The closest nesting area that I am aware of is in Lake County along
      Scotts Creek near the intersection of Route 20 and Scotts Valley Road.
      There was a sizeable nesting colony there in at least 2007 and 2008. This
      is 3.2 mi. from the Mendocino line and about 11 miles from my home. It
      could be the source of juveniles seen here and at Lake Mendocino, but local
      nesting seems more likely to me.
      If our Mendobirds members are sensitized to this issue, maybe we can
      nail the question down in the next breeding season. If they are nesting in
      the county, they seem to have slipped under the radar so far. We should
      report all spring and summer records of this species.
