    Interesting perspective. I never really thought about that. For a mammal to carry and protect its young it’s not that much of an energy sink. They eat food digest it and provide milk. Birds have to scavenge food and deliver it via airmail.

      There’s also a lot less energy spent upfront. A mammal (except that one) carries their child for a period inside of them while they grow. A bird lays an egg, which they have to care for but they aren’t as stuck with it and vulnerable, and usually for a shorter period. Essentially, a mammal’s child represents a much larger investment, so it makes sense to put more effort into ensuring it succeeds.

    I once found a baby bird and took it home. (Don’t do this. I was a kid and didn’t know any better.) Bird parents are amazing. They found the cage I was keeping their baby in and they came every day to feed him.

      Some birds do the exact opposite: if they see that a human has touched their chick (even if they just leave it in the same place afterwards) they might reject it and stop feeding it.

          Well, I was teached that by my parents, but because of your post I looked it up and apparently, as you say, that’s not true.

          So cheers for getting me to check it!

    Mother kangaroos will abandon their joeys if they are in danger so they can flee faster. If they danger passes, they will not accept their joey again.

    For context: the raven child was already ready and their parents are good parents /hj
