Leviticus 1:12-14

New Revised Standard Version Catholic Edition

¹² It shall be cut up into its parts, with its head and its suet, and the priest shall arrange them on the wood that is on the fire on the altar; ¹³ but the entrails and the legs shall be washed with water. Then the priest shall offer the whole and turn it into smoke on the altar; it is a burnt offering, an offering by fire of pleasing odor to the Lord.

¹⁴ If your offering to the Lord is a burnt offering of birds, you shall choose your offering from turtledoves or pigeons.
