Ruddock.
The redbreast, sacred to the household gods. The legend says if a redbreast finds a dead body in the woods it will cover it with moss. Drayton alludes to this tradition

Covering with moss the deads unclosed eye,
The little redbreast teacheth charitie.
The Owl.
Shakespeare makes Arviragus say over Imogen

Thou shalt not lack
The flower thats like thy face, pale primrose; nor
The azured barebell the ruddock would
With charitable bill bring thee all these.
