 Another account from that voyage , perhaps the first to mention the dodo , states that the Portuguese referred to them as penguins . The meaning may not have been derived from penguin ( the Portuguese referred to them as " <unk> " at the time ) , but from pinion , a reference to the small wings . The crew of the Dutch ship Gelderland referred to the bird as " <unk> " ( meaning " swollen " ) in 1602 , a name that is still used in some languages . This crew also called them " <unk> @-@ <unk> " and " <unk> " , in reference to fowl fattened for the <unk> festival in Amsterdam , which was held the day after they anchored on Mauritius .
