A mother and her one-year-old baby have been rescued from the Colombian jungle after surviving for four days before being recovered.

Maria Nelly Murillo and her child were aboard a twin engine light aircraft when it crashed on 20 June into thick jungle in Colombia's remote western region.

Their pilot was killed in the crash, but the pair were miraculously saved after a load of fish on board the flight cushioned their impact in the cabin, AP reported.

Rescuers found Murillo and her son after following a trail of clues left through the jungle, including a flip flop, a birth certificate and the remains of eaten coconuts.

Murillo told rescuers she climbed a hill with her child to get away from the plane, which she feared might explode.

She said she survived on coconut water until a local person came across her and summoned help.
