Condor numbers fall at California's Pinnacles National Park amid lead poisoning

The California condor flock monitored at Pinnacles National Park has decreased to 106 birds, down from 114 the previous year. Conservation officials attribute the decline mainly to adult deaths and failed nesting attempts caused by lead poisoning. Ventana Wildlife Society executive director Kelly Sorenson emphasized the need for wider availability of lead‑free ammunition, noting that California law requires it but the market does not fully support it.

During the current season, two nesting trios were observed but produced no chicks, underscoring how lead exposure can disrupt breeding. While the statewide condor population approaches 600 individuals, the species' slow reproductive rate means each adult loss has a disproportionate impact. Officials are also monitoring for avian influenza as part of ongoing conservation efforts.
