Westchester police responding to a complaint last Friday found about 30 goats and rams plus crates of chickens, ducks, quail, turtles, pigeons and doves.
Society for the Prevention of Cruelty to Animals chief Ken Ross says Greenburgh resident Luis Perez-Hernandez and his son had planned to sacrifice the animals in a ritual of the Afro-Caribbean religion Santeria.
Religious animal sacrifice is not illegal. Both men have been charged with misdemeanor animal cruelty because two animals died.
A woman who answered the phone at a number listed for Perez-Hernandez said neither man was available for comment.
