31 July 2018: end of season wrap-up

Well, here we go. Today marks the end of my 9th year conducting spring/summer monitoring for window-killed birds at the Noble Research Center. Tomorrow I begin year 10. Ten years of near daily monitoring of window-killed birds. Here’s a quick 9-year wrap-up:

  • 40: average minimum casualties annually
  • 360: total casualties (minimum)
  • 64: species confirmed as fatalities

Top ten (eleven) species most commonly encountered as casualties at this site:

  • Lincoln’s Sparrow (45)
  • Ruby-throated Hummingbird (29)
  • Painted Bunting (24)
  • Indigo Bunting (20)    *tie*    Grasshopper Sparrow (20)
  • Mourning Dove (17)
  • Clay-colored Sparrow (16)

31 July 2018 – Black-and-white Warbler

To close out spring/summer 2018 monitoring, I found this beautiful Black-and-white Warbler today in the southeastern alcove.

I think it’s a hatch-year male, i.e., one of this season’s babies on its first journey south. Sadly, this is as far south as it got.

30 July 2018 – Ruby-throated Hummingbird

There was a Ruby-throated Hummingbird in the southwest alcove today.

A sad bonus was this Blue Grosbeak at the Food and Agricultural Products Center.
