Twice now we have had wild birds crashing into out front living room window. The first one looked unhurt but the second died almost instantly. I have no idea why it keeps happening. Once is rare but twice is just strange. Our windows are quite large and we have blinds, would that cause the bird not to see the window? If anyone has any experience of this or explanation of this, i would be grateful. Its not nice when your just sitting there and a bird comes crashing into your window.
