Three straight years of wet winters appear to be benefiting water bird species in the state, with some species showing a more than doubling in population since last year, according to the California Department of Fish and Wildlife. Total breeding duck populations in California increased 27%, with mallards increasing 49%. Gadwall numbers are up 104%. … These gains were accomplished with even more development and changes in agriculture to less water bird friendly crops continue to decrease habitat in the state. … For perspective on the loss of habitat statewide, mallards remain below the long-term average by 16%.
