In a tall tree with trunk cavities, animals face struggle for existence mainly for:
- Limited shelter: Different cavity‑dwelling animals like squirrels, birds, bats or insects compete for the same safe holes for nesting, roosting and protection from enemies.
- Limited food: Insects, birds and small mammals depending on same fruits, seeds or insects of that tree compete among themselves for the available food on branches and within cavities.
