In a bid to control the ever-growing population of squirrels, officials at Santa Monica's Palisades Park are injecting them with birth control medicine. The squirrels will be injected with an immuno-contraceptive vaccine meant to stunt sexual development as a form of birth control. The officials decided to opt for this method of birth control after other methods like euthanasia; poison or gassing failed to control their population. There are around 1,000 squirrels in the Park that can be aggressive and dangerous to the health of people they come in contact with.

Santa Monica city officials have said they will be giving squirrels a birth control shot in hopes of controlling the city's problem of squirrel overpopulation, which some health experts say is a public health risk. Officials will be injecting squirrels in Palisades Park with GonaCon, an immuno-contraceptive developed by the U. S. Department of Labor that stunts sexual development. GonaCon stops female squirrels from ovulating and lactating and stops testicular development in male squirrels. Researchers say it takes about three months for the shots to show their effects.

A Dallas-bound American Airlines flight from Tokyo was forced to make an emergency landing in Honolulu after its pilots heard some noise in the cockpit; which later turned out to be a squirrel. Airline spokesman John Hotard told The Honolulu Star-Bulletin, the pilot made the decision to land midway as he feared that the animal could have chewed through wiring or caused other problems.
