Instinct kicked in as an eagle adopts the egg of its last meal. Weird.
A pair of bald eagles has become an Internet sensation with hundreds tuning in every hour due after a roosting raptor discovered an egg inside a duck that became dinner and took it under its own wing.
The eagle discovered the egg inside a duck during dinner, and Ponder said what happened next must be instinct.
Yet, after incubating her own eggs for 35 days, Ponder says the odds are slim the eagle will stick around for another 28 days to hatch the duckling.
“My guess is she will abandon the egg as the chicks become more demanding,” Ponder admitted.
There’s also a distinct chance the eagle will abandon the duck if it even hatches, as she will instantly recognize it is in fact not an eaglet. And eat it. That would be my guess. So odds are that the duck’s fate is already sealed.
There are well known cases of bird that will accept and incubate eggs that are not their own. It’s called “brood parasitism“. Cuckoos are a well known case.
