I’ve personally witnessed many birds die flying into windows in a detached single family homes. Multiply that by ~3000 homes and 6k per year would be a massive underestimate IMO. It’s uncommon with small windows, but a glass sliding door or big picture window regularly gets a thump. Some get back up, but many don’t. I do live in an area with a lot of birds so that may be a major factor.
