Mammals: Mink Huge beaver lodge on west side of Artist Pond Lots of Russian Olives in coyote scat I also wanted to try and observe any response to the Russian Olive removal efforts at these properties. I did notice a possible change in behavior amongst Whtie-crowned, Song, and American Tree Sparrows. When thickets of Russian Olives once ringed many of the waterways and water bodies of these properties, these three species would rarely flush when I would be at close proximity to the vegetation. They would mostly hop around the interior of the structure and appeared quite secure. Today and last week I saw these species utilizing existing rabbitbrush (which is impressive in structure),cottonwoods, peach-leaf willow, and coyote willow released in areas of R.O. removal. In the last couple of weeks, when my presence became to close for comfort these species would flush to the nearest cattail/ bullrush stand. My visits have been primarily informal and may not speak to what changes might really be going on, if any at all. Just thought I would pass along the observations and welcome any thoughts or feedback.
