Dawn Treader Valley some people think it's a curse

Both canids lurched forth, and the birds scattered. Veering away from his companion, Tumbleweed cut one of the birds from its chosen escape route, and sent it fluttering and scuttling in the other direction- hoping it might cross Citrine's path. He set his sights on another, one who ran directly away from him- and knowing his own speed in comparison, Tumbleweed grinned and pursued. 

Paws and claws against sand sent little grits flying behind them. When he gained on the bird it swerved but so did he, keeping it in his line of vision easily. It was only when he came within a few feet that the bird began more evasive maneuvers, causing him to skid and swerve, left a few more feet behind when the bird started off again before he caught up. With a dash of a paw, he swept the bird's feet out from under it, and it fell into his outstretched limbs, cradled for a moment before it was crushed in his jaws.
