Migratory Birds/ Other Protected Species

  City of Ennis Department of Health Services  

Migratory Game Bird Regulations/ Other Protected Species

Migratory fowl (egrets, herons, barn swallows etc.) usually arrive during the months of March & April of each year.  

Although this natural cycle can be beautiful, the challenges associated can be overwhelming. These concerns relate to noise, odor and significant amounts of excrement that covers streets, sidewalks, cars, mailboxes and other public and private property.
City staff is unable to address any of these issues while the birds are nesting due to their "protected" status provided by the Migratory Bird Treaty Act. The City needs the help of its residents to address this challenge proactively. We encourage you to take the steps below to protect your trees and to remain vigilant in observing bird activity in your neighborhood:

  • Thin tree canopy to allow sunlight to shine between limbs and other trees 
  • Remove old nesting material 
  • Use reflective tape, scare-eye balloons or other visual deterrents to make your trees less attractive to migratory birds in search of viable nesting sites 
  • If you notice egrets or herons in your trees, use water hose or signal horns to scare birds from the trees
