Migratory Birds (Egrets / Herons)

April 1, 2020 - In order to prevent cattle egrets from nesting in the City of Allen, predatory bird noise-making devices will be used at Stacy Ridge Park.

The noise-making devices may be used while the threat of cattle egrets nesting is high.

If cattle egrets are sighted in Allen, the prevention efforts will then switch to the use of “percussive” devices that produce a loud bang. These devices sound similar to fireworks or gunfire and residents should not be alarmed. This measure must begin immediately upon a cattle egret sighting and may not provide an opportunity for advance notification to the surrounding neighborhoods, though communication efforts will be made to keep the public informed.

For questions and more information, please call the Allen Parks and Recreation Department at 214.509.4700. To report possible signings of cattle egrets, night herons or other major migratory bird activity, please visit the online help desk.

Protecting Public Parks and Greenbelts

 
The devastation caused by large nesting sites such as the ones we have experienced in Allen can be tremendous. In 2013-2014, hundreds of homeowners and families were affected, two of our most beautiful parks sustained substantial environmental damage, and thousands of dollars in clean-up costs were incurred. You can learn more about the previous nesting sites by reading the brief history of Cattle Egrets in Allen.

It is important to remember that once a single egg is found in a single nest, these sites become protected under federal law and everyone, City staff and residents, is prohibited from interfering or harassing the birds. The best way to avoid the residential and environmental impact that can occur is to prevent the birds from establishing their nests at all. 

Predicting where migratory birds will ultimately choose to nest is nearly impossible. However, since these birds typically attempt to return to the same site as the previous year, that is where Parks and Recreation staff will focus their surveillance and preventative efforts first. In addition, staff has completed a review of the entire park system in Allen and identified other areas of possible concern. Those areas will also be closely monitored with available staff.
