vultures spell very bad news. They also tend to fold their wings and drop out of the sky if they see you coming
I saw one hawk do the same thing as I came up behind him in a glider.
Our local vultures seem quite used to our joining up with them in thermals.
As for a landing light getting birds out of the way, it doesn't always work as I once collected a bird at 3am; however, it did give me time to duck
