Science and Stewardship on the Upper Texas Coast
Least Tern chick
The arrival of spring means the return of beach-nesting birds to the Upper Texas Coast. Unlike birds that nest in trees or marshes, these species rely on the open beach for survival. Houston Audubon, in partnership with American Bird Conservancy, manages these vulnerable populations through a combination of direct monitoring, symbolic fencing, and public stewardship.
From March through August, fencing is placed around the dunes and beaches where these birds raise their chicks to protect them from disturbance. The fencing doesn't restrict recreational access to the beach itself, but serves as a reminder to give ample space for the diverse wildlife we are fortunate to share our stretch of coast with.
Share the Shore: How you can help
Human activity, off-leash pets, and vehicles pose a serious threat to beach-nesting birds, who rely entirely on camouflage for protection. When parents are flushed from their nests, their eggs and chicks become easy targets for predators and the harsh coastal sun. Because these nests are so well-hidden, they are often accidentally stepped on or run over. Over time, repeated disruptions can force birds to abandon their nesting sites entirely.
To ensure these birds can safely raise their chicks, we ask all visitors to adhere to the following protocols:
Least Tern nest
March - August
-
Walk in the wet sand
Baby birds and eggs blend in perfectly with the dry sand, so staying in the wet sand will help you avoid accidentally stepping on any nests.
-
Stay 50 yards away from posted nesting areas
When humans or pets get too close, parent birds perceive a threat and flush (fly away) from the nest. Constant disturbance can cause the bird to abandon eggs or chicks entirely. If you get too close or notice an agitated bird, walk away and give them space.
-
Leave found chicks alone
While it's a natural instinct to want to rescue a chick standing alone on the sand, in the vast majority of cases, interference does more harm than good. Just because you don't see an adult doesn't mean they aren't watching from a distance, waiting for you to leave so they can return.

Watch your step and maintain vigilance
While fencing is placed to protect key nesting areas on the Bolivar Peninsula, it is worth watching for nesting birds wherever you may be enjoying time on the beach.
Year-Round

Keeps pups on a leash
Because chicks and eggs are perfectly camouflaged, a dog running through the sand can easily trample a nest or kill a chick before you even realize they were there. Additionally, shorebirds often flush their nests from a much greater distance when a dog is present, keeping parents away from their eggs for longer.
-
Don't scare birds into flight
Every time a human or dog causes birds to fly away, they burn critical energy needed for feeding their young or surviving their upcoming migration.
-
Properly discard fishing line
Shorebirds, sea turtles, and marine mammals cannot see thin fishing lines. Once they swim or walk into it, the line wraps around their legs, wings, or necks. Because the line is designed not to break, the animal often becomes immobilized, leading to starvation, amputation, or drowning. Standard monofilament line takes approximately 600 years to decompose - a single piece of line can continue to kill wildlife for generations.
-
Pick up trash (or join a beach clean-up!)
Leftover food scraps, wrappers, and containers attract predators. Many coastal birds are opportunistic builders, mistaking trash for natural nesting materials, leaving chicks vulnerable to entanglement in their own nest. Birds also mistake small pieces of plastic for food. Since plastic doesn't digest, it sits in the bird's stomach, creating a false sense of fullness that leads to starvation. Sharp edges on plastic shards can also puncture internal organs.
Focal Species
Our monitoring focuses on three primary species of concern, whose cryptic nesting habits leave them uniquely vulnerable to human-caused disturbance.
