観察結果の詳細
Trees on side of the road surrounded by mowed prairie with the Platte River to the south. This count is a very conservative estimate as I did not have time to count them all before they flew. There may have been as many as 30 all in the same two small trees, but there were also Red-Winged Blackbirds in the area. It was dusk and I could see that most of the birds in the 2 trees were not Redwings but could not tell in the dim light if they were Brewers or Rustys. There were redwings in other trees. I took a few photos before they flew to process at home for for confirmation.
