In general, hunters need a hunting license and a special permit or tag to hunt Rocky Mountain bighorn sheep and mountain goats.
Step-by-step explanation:
The license requirements for a Rocky Mountain bighorn sheep can vary depending on the state and country where it is found. In general, hunters usually need to obtain a hunting license and apply for a special permit or tag. These permits or tags are limited in number and are typically awarded through a lottery or a points system.
As for mountain goats, the license requirements also vary by location. In many places, a hunting license is required, along with a specific permit or tag. Similar to bighorn sheep, these permits are often limited in number and distributed through a lottery or points system.
It's important to note that hunting regulations can change, so it's best for hunters to consult their local wildlife management agency or department for the most up-to-date and accurate information.
