Meet B327 and B326 – 3 to 4-week-old baby bobcats at Santa Monica Mountains National Recreation Area in California. The park’s biologists recently ear-tagged these kittens as part of a 20-year-long study of how urbanization has affected bobcats in the Santa Monica Mountains and surrounding area. Biologists have been tracking the mom, B255, since 2010 and tagged her kittens while she was away from the den. The ear tags will help identify the cats in remote camera images.
