A package of tiny dead birds hidden in a passenger's bag has been confiscated by Customs agents at a Virginia airport. U.S. Customs and Border Protection intercepted the package at Dulles International Airport after the passenger landed on a flight from China on January 27. The passenger told agents that package of dead birds was just cat food. The plastic packaging had pictures of a cat and dog on the outside - similar to what pet treats look like. Inside the bag were a number of dead dried birds, which were about 2.5 inches to 3.5 inches long.
