This bird landed on the back of our boat in Hawaii we’ve never seen a sea bird do this while in the slip she went to the bathroom on our boat and it was bright yellow we think she was sick because we’ve never seen a sea bird do this before would you happen to know anything more
I was away and did not see your comment until today. Most likely just something the bird ate, although less likely other explanations could be a parasitic infection or even liver disease, but if the bird was behaving normally it probably will be OK. In any event it’s nature, and not much you can do about it.
