What is crow yellow beak?

As an AI language model, I don't have access to any specific information about a crow with a yellow beak. However, typically, a crow's beak is usually black, and it is a very strong tool that helps the crow with its survival needs, such as cracking nuts or catching prey. Some crow species can have small spots of yellow on their beaks. Generally, the yellow color may indicate that the crow is a juvenile or an older adult.
