This is the moment a young owlet pounced on an unwitting sibling as it practised its hunting techniques.
The series of images capture the action as the airborne fledgling dives in “for the kill” on another unsuspecting owlet which is left shocked and its feathers ruffled.
The amusing air-to-ground attack was snapped by Rob Palmer as he photographed Burrowing Owls near the town of Pueblo, Colorado, USA.
Rob said: “I am always looking for action and interaction with these small owls. At this age they are testing their wings and attack skills and their siblings are the target.”
The 62-year-old wildlife photographer from Longmont, Colorado said: “They do not harm each other at all but it sure looks as if they mean business.
“They can hunt now but mainly insects like grasshoppers and crickets.”
In recent years Burrowing Owls have suffered from habitat destruction, they rely on active communities of prairie dogs – known as prairie dog towns – as they use their burrows.
