Rescue crews were searching on Thursday for seven people still missing days after an explosion at a fireworks warehouse in Northern California shook a tiny farming community and forced the cancellation of nearby July Fourth celebrations.

H uman remains have been found at the warehouse filled with fireworks that exploded in Northern California this week, officials said. The number of fatalities was not released and no positive identifications have been made, Yolo County officials said. Seven people were considered missing on Wednesday.

No positive identifications have been made, and recovery efforts are still underway, the county said in a statement.

"Disturbing roosting migratory birds at night can result in mass deaths," says Bateman. "Disturbing breeding birds can result in colony collapses. Seals and sea lions leave [affected] areas and expend energy swimming away during fireworks."
