  • In South Texas, watch out for ocelots crossing roads

David & Marianne Book have been volunteers, supporters & contributors on many levels for Laguna Atascosa National Wildlife Refuge. His children's books are a popular item at the Nature Store, and his history book on the Refuge was a particularly challenging puzzle to pull together. I look forward to his blog for bits and pieces to be brought to life among other topics regarding the habitat and conservation efforts of Laguna Atascosa.

In South Texas, watch out for ocelots crossing roads

On the main road of the Laguna Atascosa National Wildlife Refuge in South Texas, two ocelots recently jumped out in front of a car. The mother ocelot then went back across the road for a kitten in the brush.

Sightings of ocelots like this are rare in the refuge, even though it’s home to a breeding population of these wild cats. Ocelots are typically nocturnal and most active just after sunset and before sunrise, when they can hunt under the cover of darkness. The cats are quite shy and prefer to stay hidden in the brush of their preferred Tamaulipan thornforest habitat. While visitors often spot bobcats at the refuge, this glimpse of the ocelot family was an unusual and special encounter.

Though exciting, its setting on a road is a sobering reminder that when traveling through South Texas, you’re in ‘ocelot country.’

The ocelot is now endangered in the U.S., but it once thrived from South Texas to South America, hiding in the deep grasslands and thornforest. Now, just 1% of the ocelots’ optimal habitat remains in South Texas, most of which is fragmented and separated by high-speed highways.

As a result, accidental vehicle collisions have been an unrelenting threat to ocelots. In the past 20 years, most documented ocelot deaths occurred on Texas roadways. Between 2015-2016, eight ocelots were killed by vehicles over a span of just 11 months. With only 60 to 80 ocelots left in Texas, these losses are both substantial and unsustainable.

The surge of road-killed ocelots over that difficult year, however, prompted fast action and change. Led by Texas Department of Transportation and the U.S. Fish and Wildlife Service, the state has constructed more than 27 wildlife crossings, many built in ocelot-occupied areas. When developing these crossings, the state considered ocelot behavior – they are shy, so the crossings either provide a high level of shelter or were built underground.

Wildlife crossings work and have reduced the number of ocelots killed on roads substantially in South Texas. My organization, Defenders of Wildlife, works with leaders at the federal, state, and local levels to advocate for more wildlife crossings, including a provision of $350 million in the Infrastructure Investment and Jobs Act of 2021, to help improve the options for animals crossing busy roads. Wildlife crossings also help other resident species such as bobcats, armadillos, javelinas, and alligators, and also keep the roads clear for driver safety.

The sighting of the ocelot mother and her kitten crossing the road was both a heartwarming and worrying sight, as it reminds us of the major risks that roads pose to them and other wildlife, and the need to provide animals a way to cross safely.
