Within The Black

Have you ever seen or heard of anything like this? I am curious to know what kind of bird this was and what would cause them to just select a house and flood into it like that. It seems as thought they were in danger or something. But what were they trying to escape? Or what were they being drawn toward?

I just watched the video. This is the first time I've ever heard about this happening. I've had a bird or two fly into my house and car before, but never anything like this. Thanks for sharing the video.
