Along the coast of Southern California, seabirds that should be fat and flying are instead washing ashore emaciated and dying. Researchers at rescue centers in San Diego say they are seeing birds arrive in numbers that signal something far worse may be coming.
A warming ocean empties the pantry
The birds are starving because their food is vanishing. Warm water from the developing El Niño is pushing anchovies, sardines and other small fish deeper or farther offshore. For seabirds that must eat daily, that shift can be fatal. The birds turning up on beaches are mostly young ones, the first to weaken when prey becomes scarce. Rescuers describe them as severely underweight, dehydrated and covered in parasites.
Rescue centers brace for what comes next
Wildlife rehabilitation facilities in the region are already near capacity. Staff at SeaWorld San Diego and the nonprofit Project Wildlife report taking in hundreds of birds in recent weeks, far more than usual for this time of year. Species affected include common murres, Cassin's auklets and Brandt's cormorants. Scientists say the current die-off may be a preview. El Niño conditions are expected to intensify in the months ahead, and no one can predict how many birds will ultimately perish. One researcher put it bluntly: "We don't know how bad this is going to get."
Why locals are paying close attention
For people who live along the California coast, seabirds are a visible sign of ocean health. When the birds starve, it means the marine food web is under stress. Local fishermen also depend on the same small fish the birds eat. A collapse in prey populations can hurt both wildlife and livelihoods. The last major El Niño, in 2015 and 2016, led to massive seabird die-offs up and down the coast. Scientists fear this one could be just as severe, or worse.
This is not a story about a single species in trouble. It is a story about an ocean that is changing faster than its inhabitants can adapt. The birds washing up on the sand are messengers. What they are telling us is that the sea is warming, the food is moving, and the creatures at the top of the food chain are running out of time.
