Purple Martin Watch Parties

Presented by CenterPoint Energy

This year's watch parties were presented by CenterPoint Energy. The Purple Martins are now migrating south. Join us next year for more parties!

Location:  Historically there are two major roosts in Houston. We keep an eye on the radar for roost sizes and will select the site based on where the birds are. Roost locations are either Stafford (12634 Fountain Lake Cir, Stafford, TX 77477) or Willowbrook (17395 Tomball Pkwy, Houston, TX 77064). Please check back for locations as we may need to adjust our meeting site.

Background Information: From July to September, Houston's Purple Martins spend most of the day feeding on flying insects to build energy for their long journey across the Gulf of Mexico. At dusk, they form large flocks and roost together in preparation for migration. Join us to watch the amazing spectacle! 

We recommend you bring a lawn chair and an umbrella.

We're looking for volunteers to attend watch parties and chat with people about Purple Martins and answer frequently asked questions. Training can be provided. Sign up here.

Traditional Locations of Large Martin Roosts

  • Stafford

    The Fountains is a shopping center in Stafford at Hwy 59 and Kirkwood. If you take 59 south, exit Kirkwood and turn right onto Fountain Lake Drive. Turn left into the shopping center. The martins congregate at Gordon Park behind the center. They drink at the ponds and then perch in the trees and wires at the park and around the shopping center. The park is on Fountain Lake Drive directly behind the shopping center. In 2012, Thomas Bumby and Patrick Dusek confirmed martins were roosting at the Stafford site on June 2-3. Donald Troha located the martin roost on weather radar as early as June 8 and on the evening of June 13 counted 3,000 birds. Prior locations for this roost were the KBR Building on Clinton Drive in Houston, the west side of Sharpstown Mall, and just south of the Galleria on South Post Oak.

  • Willowbrook Plaza

    Current roost location: 17395 Tomball Pkwy, Houston, TX 77064. Meet in the parking lot on the south corner of Gessner and Highway 249

Peak numbers for Purple Martins occur in July and August when Purple Martins form large flocks and roost together in great numbers in preparation to migration. Some roosts may have thousands of birds. When the birds arrive to roost in the evening, it can be an amazing spectacle with the sky literally black with martins! If you know of a large roost, please contact us at birds@houstonaudubon.org. We have prepared an informational flyer about communal roosts, suitable for display. Join us in helping to protect Purple Martins!

Radar Sightings

Purple Martin flight patterns are sometimes visible on weather surveillance radar. The patterns can resemble rings which are particularly dense as they disperse to forage in the early morning.
