To ensure the protection of the bird species, WSIP biologists Elizabeth Gruenstein (pictured to the right) and Jill Grant are hanging shiny nesting deterrents in trees around the BDPL3&4 jobsite in Fremont. Owl shapes, “eyes” and reflective ribbon will scare away birds that come to nest near construction. In years to come, birds will return to the same trees to nest.
White tailed kite and red-tailed hawk are among the species
that biologists hope to keep away from construction.
The SFPUC communications team has spoken with a number of residents around the jobsite who have approved the placement of deterrents within their properties. If you have any questions about an unexpected object hung on one of your tree limbs, don’t hesitate to call our 24-hour answering service at (566) 973-1476. Thanks for helping us protect our wildlife!
Balloon deterrents have large “eyes” which scare birds
that would otherwise nest too close to construction.
