Birds’ nest collectors on Thursday joined efforts to rescue the young Thai soccer team trapped in an underground, partially flooded network of caves for almost two weeks.

The group of eight men used their generations-old climbing skills to scour a mountainside for openings that could lead rescuers to the 12 boys and their soccer coach trapped below.

“One member in our team was watching (the rescue mission) on television and thought, ‘How can we help them?,'” group leader Abdulrawheep Khunraksa told AFP.

“We thought that we might have the expertise to help since we have climbed to collect birds’ nests for generations,” the 49-year-old added.

The men, Thai Muslims from Libong island, have experience scaling sheer limestone cliffs and exploring crevices to collect edible nests made from solidified bird spit — a delicacy that can net them hundreds of dollars for every two pounds.

Armed simply with ropes and gloves, the group, ranging in age from their 20s to 50s, used their expansive knowledge to scale steep slopes in the hopes of finding an opening to the Tham Luang cave.

Rescuers were also frantically trying to drain water from the cave Thursday — before onslaughts of rain predicted this weekend.
