Changes in droppings
Twice now I've rushed my (3 yr old) lovebird to the avian vet because I've spotted small amounts of blood in his droppings. Given a few hours of observation by the vet, the droppings have returned to their normal color and consistency without any intervention, and the blood has been ruled the result of eating something scratchy. The incidences were months apart, for what it's worth.
Is it "normal" to occasionally have blood in the feces? I am hesitant to follow up with bloodwork and x-rays if it was just a false alarm, because I don't want to cause him undue stress (also, he has already had a cbc and xray within the year, and both were normal). Should I take my bird to the vet whenever I see blood in the droppings, or is it safe to wait a few hours and see if it resolves? I am wondering if the key to interpreting droppings is that there is a consistent change over, say, 24 hours. Relatedly, if the blood is no longer present and he's otherwise healthy, does that rule out a more serious problem? Thank you for your help.
