Northern California researchers have taken new photographs of two mountain lion kittens they are tracking.
The Press Democrat in Santa Rosa reports the Audubon Canyon Ranch research team captured pictures of the kittens Aug. 2 in Sonoma County's Glen Ellen, north of San Francisco.
Researchers say the mountain lion, named P1, gave birth to three kittens in April but they believe only two are alive.
The kittens were last photographed when they were just 10 days old.
The kittens are expected to stay with their mother for up to two years before they separate and hunt for themselves.
The team follows P1's movements through her GPS collar.
