A most interesting site. 75% of the cattails are occupied by nesting tricolors. The remaining 25% is occupied by nesting Redwings. Also, there is approximately 450 square meters of H. Blackberry on the back edge of pond that is occupied by tricolors. In addition, we observed Black-crowned Night Herons moving about the cattails in search of eggs or chicks. A couple of Green Herons were observed as well. This is the first site in Placer, Yuba, or Butte, that I've observed tricolors using cattails.
