Crows: Behavior and Recognition

The video explores how crows interact with humans, focusing on their ability to recognize human faces. It follows the research of wildlife biologist John Mars Louf, who investigates how crows adapt to urban environments and their survival strategies. The video explains the scientific process used to study crows' recognition abilities, including the use of masks to test face recognition. It concludes with findings on crows' memory and recognition skills, highlighting their adaptability in human-dominated environments.

What role do light receptors play in a crow's vision?

• They enhance the color of objects

• They block light from entering the eye

• They help crows hear better

• They send information to the brain

What was the main variable changed in Mars Louf's investigation on crow recognition?

• The location of the crows

• The type of food given to crows

• The masks worn by humans

• The time of day the experiment was conducted

Why did Mars Louf use masks in his investigation?

• To make the experiment more fun

• To protect the crows from sunlight
