In most cases, mild to severe head trauma
(concussion) is common and must be treated as soon as possible.
Handle the bird as little as possible,
and very gently as broken bones are common.
Do not stress the bird by holding
it or allowing people to “come look”. Humans are predators to a bird. The
torment of prolonged handling or exposure to humans on top of its injury
or orphaning may prove too great a shock to recover from. Every non-necessary
exposure to humans worstens their chance of survival.
