Or brown, for that matter.
I'm sure that's what the little bird who just took a run at the kitchen window thought...
When he realized that it wasn't an opening to a bright new world,
But rather a 5 inch opening that ended in a screen-backed dead end.
I heard a squawk, some frantic fluttering, more squawks, and ran into the kitchen to see a bird-shaped blot hugging the inside of the window while two little clawed feet scrabbled for a foothold.
At least it wasn't stunned enough to stay flapping at the glass when I opened the window wide enough for a panicked get away.
