#23 The Arkansas Birds
In 2010, over 5,000 blackbirds in Arkansas went into a frenzy and slammed right into poles, trees, and buildings, causing their instant deaths.
While the local authorities claimed it was the fireworks that led to this “one-time incident,” this occurred again.
This incident took place yet again the following year despite a blanket ban on firecrackers.
Since then, several theories, such as the incident signaling the end of the world or the work of malevolent spirits, etc., surfaced. However, none of these theories were considered plausible.
