Lights Out Texas! Dark Skies for Bird Safety

Spring bird migration is in its peak over Texas, filling Houston with a plethora of colorful, melodious visitors. Turning out nonessential lights from April 19 - May 7 is one of the most impactful local actions you can make to save the lives of birds on their journey. As an extension of the city-wide Lights Out for Birds program, Houston Audubon has partnered with the Cornell Lab of Ornithology to launch Lights Out Texas - a science-based campaign with the goal of protecting migratory birds from the deadly hazards of artificial light. Here are the facts:

Houston is a crucial, yet dangerous flyway for migratory birds.
1 of every 3 birds migrating through the U.S. in spring passes through Texas. Houston ranks second among U.S. cities in exposing migrating birds to the hazards created by light pollution, trailing only Chicago. Most migratory birds fly at night, and the bright lights of commercial and residential buildings attract and disorient them - causing collisions or exhausting them and leaving the birds vulnerable to threats on the ground.

As many as 1 billion birds die from building collisions every year.
 "We have a real opportunity to make an impact here—to help to protect one of the planet’s greatest mass animal movements, just by turning off unnecessary lights," said the Cornell Lab’s Julia Wang who is heading up the Lights Out Texas study. "This means turning off or reducing lighting during a window of time when at least 50% of the overall spring migration traffic is moving through the Houston, Dallas, and Fort Worth areas."

BirdCast migration forecasts can predict nights of intense migration up to three days in advance.
This window of “peak migration” was chosen after scientists analyzed migration frequency and intensity using more than 20 years of data from the U.S. weather surveillance radar network. “The migration forecast maps on BirdCast back up our own Action Alerts with science," said Houston Audubon conservation director Richard Gibbons. "These visuals really help people connect the risks to birds with conservation action they can take.”

Turn off nonessential lights at home TONIGHT to join Lights Out Texas and make a difference!
Lights Out Texas organizers are calling on people in the Houston, Dallas, and Forth Worth areas to reduce or eliminate lighting in or around tall buildings, businesses, and private residences between 7:00 p.m. and 7:00 a.m. during the April 19 through May 7. See the attached fact sheet for more information!

Creating a Pocket Prairie in an Urban Backyard

In September of 2017, my girlfriend Amanda and I, along with our dog Scout, moved out of our apartment and into a house in Houston’s Sunset Heights. One of the selling points of this house was that it had a small backyard the three of us could enjoy together. It was a simple space comprised of zoysia grass, Japanese yew, and bamboo.

In June of 2018, Scout was sniffing around our backyard and decided to eat a couple of Japanese yew berries that had fallen on the ground. This led to her getting sick and spending the next two nights recovering at a veterinary clinic. This is the event that made me start to question everything growing in our backyard. Why did we have grass, shrubs, and bamboo from Asia? Why had we never seen a butterfly in our yard?

We decided we needed to make some changes. To begin my research, I read The Houston Atlas of Biodiversity by Houston Wilderness, Bringing Nature Home by Douglas W. Tallamy, and Native Texas Plants by Sally Wasowski and Andy Wasowski. After rea…

Critical habitat is closer than you think - Rice University students create a Habitat Conservation Plan to support wildlife in our city

Across the world, species are rapidly disappearing before our eyes. This is a biodiversity crisis. Urbanization has caused habitat degradation, loss, and fragmentation, which contribute to the decrease in global biodiversity. At Rice University, fifteen students signed up for Dr. Cassidy Johnson’s Conservation Biology Lab in hopes of making changes on their campus and in their city to protect and enhance the local biodiversity. These students are creating and communicating their desires to implement a Habitat Conservation Plan at Rice University in order to contribute to urban conservation efforts right here in Houston. Their project tackles specific biodiversity concerns including critical habitat, bird conservation, pollinator gardens, medicinal gardens, carbon sequestration, and wetland restoration.

The following piece is written by students in the Conservation Biology Lab who are taking part in developing that plan. This is the first post in a series.

Houston, we have an announcement. We’re now a Bird City!

We know that Houston is a vital city for birds, but now it’s official. Houston Audubon’s Conservation Team worked tirelessly in partnership with Houston Parks and Recreation Department (HPARD) Natural Resources Program to submit the application, and it paid off. Houston was honored as one of the first four cities to receive the Bird City Texas certification – an inaugural program by Audubon Texas and Texas Parks and Wildlife Department (TPWD).
So, what exactly does being a Bird City mean? The big picture is that we have demonstrated that our community cares about birds, habitat, and conservation. The growing popularity of planting native plants, restoring prairies, bird-friendly education programs, and the Houston Lights Out for Birds program to reduce collisions for migrating birds were among the many efforts and programs that got us this designation. (Go Houstonians!)
I personally witnessed the large amount of work that went into this application and was curious about what it entail…
