Migratory Birds

Preventing Heronries in Residential Areas

Fort Worth 2012

• Birds arrived in spring; stayed until

September

• Three homes had nests; entire block

affected

• Property owners working to remove old

nests, trim trees, prevent new nesting

• Birds are “programmed” to return; even

greater numbers likely in spring 2013

• Where will the birds go?

The Problem

Limitations

• Protected status under Migratory Bird Treaty Act
• f 1918 prevents nest destruction when eggs of

any species (egrets, herons, etc.) are present.

• No City tax funds may be spent on private
• property. City has helped with:

– Dead/injured bird pickup – Education

Case Study - Carrollton

• Carrollton 2011

– 1201 Nests – 4,804 Adult birds – 7,206 Chicks – 7,206 Eggs

• If allowed to return

– 10,568 Adult birds – 42,272 Eggs – 21,326 Chicks – Total birds in the rookery would have been 31,704

The Plan

• Education
• Communication
• Action Steps

Education is Key

• Learn the warning signs

– Previous nesting activity – Dense tree canopy – Scout or sentry birds

• Know what you can legally do

– Harassment methods – Nest removal

• Get organized

– Communicate with neighbors – Determine who will help and how

Action Steps

• Fall

– Remove old nests – Trim your trees – Get organized

• February

– Watch for sentry birds – Report sentry bird sightings to neighbors

• Pre-Nesting

– Make noise – Hang visual deterrents in trees – Use water hoses – Remove the start of any nest

• Air horns
• Scare-eye balloons
• Streamers
• Water guns (toys)
• Lights
• Nest removal hook
• Radios

laying has commenced by any of those birds, all nest destruction must cease. Destruction of empty nests in an active or partially active colony will likely threaten surrounding nests that contain eggs or nestlings; therefore it will not be allowed except

determined by the Migratory Bird Permits Office.”
