I think the OP said Saylor was Navy? If he was a sailor or Seabee, they were famous for wheeling, dealing and smuggling weird stuff home. Air Corps too. One of the pet obsessions of a famous Air Corps officer, Pappy Gunn, was importing Arkansas game from his home to the Phillipines. It would be no surprise if others brought birds or eggs the other way.
The poster with firsthand accounts refuting Saylor is also persuasive, especially if others could corroborate. Saipan had a huge Japanese presence, including more civilians than elsewhere outside Japan/Okinawa. So the part about the Japanese bringing in lots of other breeds makes sense.
