On the tenth day of Christmas my truelove sent to me: ten lords a-leaping . . .
Lords wear ermine robes. Ermine is the winter coat of a stoat, also called an ermine.
Stoats are wellknown for their leaping and dancing displays.
Lord Derby's Parakeet (also called Derbyan after Lord Derby) leaps well (when not flying).
