Often those who discover birds that are nestlings, injured or displaying unusual behaviour decide to wait and see how it goes before calling PROWLS.
Sometimes they call the next morning, or even in a few days. This is never a good idea. They should call right away.
If it is a case of a cat attack, the bird needs antibiotics as soon as possible. Their systems operate so much more quickly than humans, regardless of whether it be growing, healing or dying.
Even an overnight delay can prove fatal, as happened recently with a goldfinch. By the time it arrived at PROWLS, the infection had set in, which is most likely what killed it.
Even concussions are best healed in safety at PROWLS, not outside sitting in the grass, vulnerable to predators
