Another mass death: Thousands of gizzard shad fish have washed up on banks of Chicago’s harbours
Thousands of gizzard shad fish have been washed up on Chicago’s harbours while more than 100 dead birds have been found clustered on a California highway.
The two instances appear to be a continuation of the strange mass animal deaths that have struck in the past fortnight – in America and elsewhere.
However Lake Michigan Program biologist Dan Makauskas said that gizzard shad are not a very tough variety of fish and are more sensitive to drops in oxygen levels than most fish.
Mr Makauskas suggested that the young fish may not have built up enough reserves to withstand the early onslaught of extreme cold that hit the area.
Canada geese and mallard ducks have eaten many of the dead fish.
Meanwhile, California wildlife officials are attempting to work out what caused the death of more than 100 birds found clustered together just off Highway 101.
The Santa Rosa Press Democrat reports that California Highway Patrol officers found the dead birds near the roadway on Saturday and called in the state Department of Fish and Game to investigate.
The officers who found the birds described them as small with brown and black feathers.
They were intact and had not been shot.
