I dont think you can, unless you migrate a swellow or taylow and then breed from them in Pokemon Diamond, Same goes fr Pearl too :) x
breed a swellow and ditto
there is no way to teach swellow sing inless you breed.
You don't. Tailow isn't in diamond unless you migrate him from ruby or sapphire. You can also breed a female Swellow with a compatible Pokemon, or breed any gender Swellow with a Ditto. The egg will hatch into a Taillow.
I assume you are talking about Pokemon Diamond. If you are, then yes, you can breed Pokemon in Diamond.
You need to breed a Male Chatot with a Femal Swellow to have an egg
Any Pokemon (includingWailord and Azelf).
