Bird–window collisions (also known as bird strikes after the aviation term or as window strikes) are a problem in both low- and high-density areas worldwide. Birds strike glass because reflective or transparent glass is often invisible to them.[1] Previous research estimated that between 100 million and 1 billion birds are killed by collisions in the United States annually,[2] but a 2024 study on the survival rate of bird-building collision victims indicates that previous research was vastly underestimating the number of deaths caused by collisions, and in actuality well over 1 billion birds die from collisions in the United States every year.

The ducks that were able to walk away were lucky, probably not flying at full speed yet. And they were still probably concussed afterwards.
