A small greenish mute from a hawk that seems otherwise healthy most likely indicates what?

A small greenish mute from a hawk that appears otherwise healthy typically suggests that the bird has an empty crop. The crop is a part of the hawk’s digestive system, acting as a storage pouch for food. When the crop is empty, the bird may produce a small, greenish droppings that indicate the absence of food in the digestive tract. This coloration often arises from the breakdown of bile and is not necessarily a sign of distress or health issues, especially if the hawk otherwise displays normal behaviors and vitality.

Other factors, such as the hawk's feeding habits or recent activities, could also contribute to this condition, further affirming that the greenish mute is simply an indication of the crop being empty rather than a more serious health concern.
