The aviary: the walk-through tropical house, sentence 14

Keepers weigh birds often, because sick birds hide illness, since in the wild a weak-looking bird is more likely to be caught, and losing weight is often the first sign.

Who acts: Keepers, sick birds, looking bird, losing · What happens: weigh, hide, look, be, catch, lose · To what, where: birds, illness, wild, weight, first sign
