Foot Tuck

I am always looking for signs that the birds are relaxed. Any time their head is down (while eating) or covered (while preening their wings or sleeping), they are more vulnerable to a threat. A predator might take that opportunity to launch a surprise attack, so they only risk covering their eyes when they feel safe. Other comfort behaviors, like Carson’s foot tucked in the photo, indicate that they are comfortable and and not worried about their surroundings.
