The common cuckoo is an obligate brood parasite; it lays its eggs in the nests of other birds...

At the appropriate moment, the hen cuckoo flies down to the host's nest, pushes one egg out of the nest, lays an egg and flies off.

I find nature fascinating. How about you?

1. Fascinating. I find human nature very similar

to the common cuckoo.

[LuvLoogie]

2. Yes. There are often parallels in nature to our human existence.

3. Actually, it's evolution that's so fascinating.

Recently I watched a three part series (PBS? National Geographic? ) about penguins. THAT was an incredible lesson in evolution, event though it was simply intended as a discourse on penguins.

4. Who needs the paranormal when real science is so mind blowing?

It’s spectacularly impressive that nature provides this cuckoo trick. It is so much more awesome than flying faster than a speeding bullet or the other puny super powers in the comics.

Evolution is so spectacular it’s easy to understand why so many can’t believe it exists.
