Can birds see through windows? It depends, I suppose, on light and reflections. The pigeons pecking the buds of the sophora in the churchyard under our bedroom window in the morning certainly see me with my air rifle making to open the casement.
Can they hear noises inside the house? The mating ducks seem to love the courtyard under the bathroom window. This morning a pair of mallard were fussing energetically about until I turned on the shower. Then they stopped on the edge of the grass, looking up, heads cocked, and went on looking and listening all the time the water was running. When I picked up my towel they started squabbling again. I wonder if Gilbert White noticed the same thing. But no, of course, he didn’t have a shower.
