The video shows a group of black birds in a nest. The birds are seen opening their mouths wide, possibly in anticipation of food. The nest is located on a rocky cliff, and there are green plants visible in the background. The birds appear to be of the same species, with black feathers and red beaks. The nest is made of twigs and branches, and there are at least three birds visible in the video. The birds are moving around in the nest, with some flapping their wings and others opening their beaks wide. The video captures the natural behavior of these birds in their habitat.
