The California Department of Fish and Wildlife has completed its 2025 waterfowl breeding population survey. The survey shows an increase in both mallard and total duck species this year. The breeding population of mallards rose from 177,828 to 265,640, marking a 49% increase. Total ducks, encompassing all species, increased from 373,864 to 474,495, a 27% rise. Despite this growth, mallards remain 16% below the long-term average. “The survey indicated an increase in mallard abundance, and habitat conditions were good in northern California, so we expect average to above-average production for all waterfowl species,” said CDFW Waterfowl Program Biologist Melanie Weaver.
