"A hunting license is required of any person, regardless of age, who hunts any animal, bird, frog or turtle in this state (except furbearers, if the hunter possesses a trapper's license). No license is required for nuisance fur-bearing animals, depredating hogs or coyotes (see below). Non-residents under 17 years of age may purchase and hunt with the Youth Hunting License (Type 169).
Exceptions: a hunting license is not required to hunt the following:
* Coyotes, if the coyotes are attacking, about to attack, or have recently attacked livestock, domestic animals, or fowl.
* Depredating feral hogs, if a landowner (resident or non-resident) or landowner's agent or lessee is taking feral hogs causing depredation on the landowner's land.
* Fur-bearing animals, if the hunter possesses a trapper's license or if the fur-bearing animals are causing depredation."
From TPWD.
