Visited Simpson Lake County Park and the marsh area to the west of Simpson Lake.  I did a quick scan for the Tricolor Heron without any sighting.  There were Mallards with ducklings, a female Wood Duck, and several Green Herons.  In the fenced water treatment pond (to the northwest of the marsh) there were 45 Canada Geese with a single Snow Goose.
