i liked the idea about collecting birdnests. then, you could do 2 things with them(my idea! my very first!) if ther villagers had a high enough enginering, they could build an incubator to hatch the eggs(mabye aroung 3 or 4 hours in reg time, 5 or 6 in slow, or 1 or 2 in fast) and then the eggs would hatch, domesticated, and woiuld lay eggs. then hatch those eggsZ(so on...) or, you could eat the eggs, or you could hatch eggs, then eat bird. whaddya think?
