In the most likely game-related meaning, if you don’t recall your bird in Roost , it usually stays where it is, keeps doing its thing, or may eventually return to its normal/default behavior depending on the game’s rules. I couldn’t verify the exact mechanic for your specific Roost version here, so the safest answer is that forgetting to recall it should not usually make it disappear instantly, but it may leave it vulnerable or cause it to despawn if the game treats unclaimed birds that way.

What that usually means

  • If the bird is a mount or pet, it may remain out in the world until you command it back.
  • If the game has persistence, it can stay nearby and follow you, but may stop following if you move too far or log out.
  • If the game has cleanup rules, an unattended bird may be reset, hidden, or removed after some time.

Practical check

  1. Open your bird or companion menu.
  2. Look for recall, return, or dismiss options.
  3. Check whether the bird is marked as active, nearby, or stored.
  4. If the game has a FAQ or help page, search for “recall,” “despawn,” or “pet behavior”.

One caution

If this is about a mod or game mode where the bird can be attacked, leaving it out could expose it to damage or loss, so recalling it is usually the safer move.

TL;DR

Most likely, nothing dramatic happens immediately, but the bird stays active in the world until recalled, reset, or otherwise handled by the game’s rules.
