Video: Neighbors observe bear in tree in Altadena yard

NBC Los Angeles reports that neighbors gathered to observe a black bear that climbed into a tree on a private property in Altadena on Sunday morning, May 10, 2026, remaining there from 6 a.m. through at least the evening news broadcast. The article is sourced from a named neighbor (Sergio Sanchez) and includes a direct quote, with the outlet noting it reached out to California Department of Fish and Wildlife for official comment but had not received a response at publication. CBS Los Angeles and KTLA corroborate the incident, adding that the bear was juvenile and that it eventually descended and moved through the neighborhood, climbing into a second tree by 9:20 p.m.—details absent from the NBC report. This appears to be part of a documented pattern of bear encounters in Los Angeles County; readers should monitor local wildlife agency updates for the bear's final status and any guidance on preventing similar incidents.
