[edit] Question about brood parasitic birds
How come the host doesn't notice that one of the chicks is of a different species, or at least that some of the other chicks are missing? Don't birds have the ability to tell? Does the parasite's parent specifically choose hosts that can't tell?

Basically, yeah - birds don't have the ability to tell. They'll feed the one with the widest-open mouth first, then (once that one is full) the next-widest-open, and so on until the parent runs out of food. Brood-parasite babies tend to be larger, so their mouths are larger also. Bird parents have small brains that just recognize a few particular traits, and those are the traits that the brood-parasite babies overexpress.
The interesting thing about brood-parasites, incidentally, is that they can't afford to be too successful, otherwise they'll wipe out their caretaker species.DS 14:15, 20 August 2005 (UTC)
[edit] housecat?
I think it counts.
The housecat has evolved to have a baby-like cry instead of the more typical hiss or roar of a wild cat. (like a bobcat for example) The housecat is also sized like a baby.
People care for housecats, often to the exclusion of having their own kids. The housecat satisfies a maternal longing.

- Housecats may have been bred for size and (relative) tameness, that makes them pets, not brood parasites. jimfbleak 05:10, 12 August 2006 (UTC)
[edit] Cuckoo wasp
I put in a brief mention of the cuckoo wasp - an amazing and beautiful critter I had the pleasure of watching last year. They are metallic blue-green. I know they occur in Australia, not sure about elsewhere in the world. Would be worth finding more info on them for the article. Gemfyre 06:59, 11 October 2006 (UTC)
