The ill-fated Jeju Air plane in last month's deadly crash received a warning from air traffic control about bird activity just one minute before its black box recording stopped, the transport ministry said on Saturday. 

The ministry briefed the preliminary findings to the bereaved families following its probe into the fatal crash of the low-cost carrier plane from Bangkok that killed 179 people on board and left two survivors, in South Korea's southwestern city of Muan on Dec. 29 of last year.
