What does a black bird flying across full moon mean?

In many cultures, a black bird flying across a full moon is a symbol of bad luck or misfortune. For example, in Filipino folklore, such an event is seen as a sign of impending doom. In other cultures, it may be seen as a warning to be careful or watchful, as something negative may be on the horizon.

However, it's important to note that these are just cultural beliefs and superstitions. There is no scientific evidence to support the idea that a black bird flying across a full moon has any real impact on a person's life or luck. Ultimately, the interpretation of such an event is a matter of personal belief and cultural context.
