Is there any reason why there is yellow skin on the "face"? On both sides.

These yellow marks are normal on an adult Black-faced Spoonbill. They are slightly more prominent in the breeding season and less obvious in winter. Younger birds normally don't have these, and the face is completely black.

Thank you for the information. The comments help me to understand the BFS and will be helpful in observing the beautiful creature.
