Sometimes this work can be rather surreal. This morning, while working with Scott Loss on training a group of undergraduate students in monitoring buildings for window kills, the students were looking in exactly the right direction to watch a young cardinal fly into a window about 10m away. The bird, a HY male, lay on his back stunned for a minute or two, then it perked up and flew strongly before perching in a Japanese maple very near to us. He was groggy, but I’ll assume that he’ll recover in the absence of evidence to the contrary and record him as “stunned”.
