Utterly Mad

Upon landing, the Avians immediately start dismantling the ships, using the sails as makeshift 'stretchers' for the wood and metal brackets and heading towards the island's mountain.   When they arrive at the base of the mountain, they begin to set up a base camp, using the sails to make tents and beginning construction of some treetop shelters, using up the majority of the wood and brackets in the process, and using up the rest to create tools.
After the constructions are mostly done, some of the Avians split off into a resource gathering group and a construction group.   The resource gatherers split off into miners and woodsmen, with the miners, well, starting to attempt to mine out stone, and the lumberjacks creating a path back to the beach, bringing back tree trunks and such for the construction team.

Man I'm bad at doing this.
