City of Troy Crow Roost Dispersal

City of Troy Crow Roost Dispersal

For Immediate Release:

Starting on Monday, Dec. 19, in concert with wildlife biologists from the U.S. Department of Agriculture’s (USDA) Wildlife Services Program, the City of Troy will commence a crow roost dispersal effort. The effort will run for five consecutive evenings from roughly 3:30 p.m. to 9 p.m.

Every year, large congregations of crows migrate to Troy during the winter months. Over the past few years, the numbers have increased dramatically. This year’s estimate is in excess of 10,000 birds. The larger roosts’ number in the thousands and cause property damage, as well as health concerns and noise problems for our residents.

This dispersal effort will break up the roosts with the use of pyrotechnics, spotlights, non-harmful lasers, and amplified, recorded crow distress calls. Several of these methods produce loud noises and flashing lights, (similar to sirens and fireworks) that startle the birds and may be heard or observed by residents.  

These methods will not harm the birds.

Biologists will be wearing uniforms and a yellow vest marked “USDA Wildlife Services,” and will be deploying pyrotechnics, spotlights, lasers and amplified electronic recordings of crow distress calls.

In subsequent weeks, follow-up efforts will be conducted to keep the birds from re-establishing large roosts.

Residents are strongly encouraged to place household trash in containers with lids to discourage crows from feeding.  Residents may also use bright flashlights to disperse crows roosting in trees. 

This wildlife management operation will break up and disperse large roosts into smaller groups that will spread out over a broader area, reducing the damage and mess resulting from dense concentrations.

City and Wildlife Services representatives recognize the management project techniques may be disruptive and respectfully request public cooperation as crews work throughout the city. Residents are asked to assist the effort by emailing [email protected]  to report the locations of large groups of crows.
