So if you’re stuck in traffic watching a scofflaw sprinkler douse asphalt, contact Caltrans at (213) 897-3656.

How has the effort to shrink the pigeon population in Hollywood gone since the city announced it in July?

Since August, some of the area’s estimated 5,000 pigeons have been eating pill-shaped, contraceptive kibble known as OvoControl P from feeders on Hollywood rooftops, the first area to try the contraceptive since the state approved it.

Every morning about 300 pigeons consume the kibble, which contains nicarbazin, an ingredient that stops an egg from developing.

Laura Dodson, president of the Argyle Civic Assn., said the neighborhood group leading the effort raised more than $50,000 from businesses and residents to install five automatic rooftop feeders. Cameras allow online monitoring of the birds.

After four months, the 438 pigeon regulars in one spot dropped to just under 40. The pigeons are “just having less babies now,” Dodson said.

The original goal was to reduce the pigeon population by 50% by 2012, but Dodson said officials think it could happen within two years. The pigeons are disliked because their droppings defile cars and buildings.
