The bald eagle was minding its own business, tending to two eggs in a nest that's being monitored by the Pennsylvania Game Commission.
But those watching the livestream Saturday night got quite a suprise. In a matter of seconds, it was clear the eagle was becoming increasingly agitated by something going on overhead.
And then it happened.
The nesting eagle gets up just as the intruder drops in for a landing, resulting in both eagles doing some serious posturing and wing beating. The intruder then flushes the resident eagle out of the nest.
The victory was short-lived.
The intruder stays on high alert and surveys the area, but it wasn't long before one half of the nesting pair dove into the nest to address the situation. The intruder is gets scared off, but not before the eggs got jostled on the way out.
According to Penn Live, the eggs appeared to still be intact and on Sunday, the eagles had resumed their nesting routine.
While bald eagles are incredibly beautiful, they can have a mean streak. During nesting season, they are especially territorial and will try to keep other bald eagles out of their own nesting territory, which can be up to two square miles.
