SALISBURY, Md. (AP) _ Authorities charged two brothers with the theft of 200 ducks from the city zoo after the men aroused suspicion by requesting a large supply of wildlife transfer forms from the U.S. Fish and Wildlife Service.

A clerk for the Fish and Wildlife Service contacted Natural Resources Police after receiving the request for the unusually large number of transfer forms, a DNR spokesman said Tuesday.

Robert Lee Caloway, of Delmar, and David Caloway, of Eden, are charged with breaking and entering, three counts of felony theft and three counts of conspiracy, said Ernie Mosby, the DNR spokesman.

Two-hundred ducks representing 29 species were stolen from the Salisbury Zoo between Jan. 8 and Feb. 4.

The DNR said 197 of the ducks were recovered during its investigation. Two died and one flew away, Mosby said.
