Gladewater has dealt with an abundance of buzzards before, most recently in the spring and summer of 2009.
State wildlife expert Steve Epperson helped the city get rid of the problem in the past and has been contacted again.
Officials say buzzard droppings are a threat to the water tower's paint job, which runs about $80,000. The birds also can damage telecommunications equipment on top of the tower.
Gladewater, a city of about 6,500 residents, is 115 miles east of Dallas.
