When Do Bears Hibernate in New Mexico?

Yes. New Mexico bears go into their dens in mid October and come out between late March and mid April, by New Mexico Wildlife's den and wake months.

In mid October. New Mexico Wildlife: “A pregnant female bear will begin hibernation around mid-October, give birth to her cubs in the den around January or February, and will remain there until about mid-April, ending hibernation weeks later than males or females without newborn cubs.”

Between late March and mid April. New Mexico Wildlife: “Young independent females and males den alone and may emerge as early as late March, depending on the weather.”

In late March, when the first bears wake. New Mexico Wildlife: “Remove fallen fruit, pet food and bird feeders from areas accessible to bears.”

In mid November, once bears are in their dens by New Mexico Wildlife's den months.

Some do. New Mexico Wildlife: “They are also quickly aroused if disturbed, potentially leaving their dens if discovered by other animals or humans, or if their den becomes flooded out, collapses, or is otherwise made unsuitable.”

In the den, in midwinter. BearWise: “An average of two to three cubs are born in the den in January/February.”

In July. Of 758 research grade black bear records on iNaturalist in New Mexico, more were made in July than in any other month, and the fewest in the den months.
