Retreat is useful behavior
A hiding place gives an animal control over exposure. That is biologically meaningful even when a human would prefer to see the iguana.
New environments
Recently moved or newly housed animals may spend more time concealed while they learn predictable routines and surroundings.
Read changes, not just presence
A normally visible iguana that suddenly hides constantly deserves a broader look at temperature, social pressure, disturbance and general condition.
Health boundary
Hiding paired with appetite loss, weakness, injury or other concerning signs should be assessed medically rather than explained only as temperament.
