Name that tune?

I was watching a Warner Brothers cartoon the other day, heard a tune I'd forgotten, and can't get it out of my head. The cartoon involved two black birds (I think magpies?) and these bird hopped around raising havoc and never make a sound except for da da da didda da da, da da da didda da, didda didda da da, didda didda didda da da, da da da didda da da or at least something to that effect. The music was orchestral not sung. I'm wondering if this is some classical composition or something I couild buy?
Thanks for your help.
