Manymigrating birds have strangely died in the south-western US. Ornithologists have called it a national tragedy likely to be due to climate crisis. A professor said that flycatchers, swallows and warblers are among the species falling out of the sky as a part of mass die-off across New Mexico, Colorado, Texas, Arizona & Nebraska. Many carcasses have little remaining fat reserves and many volumes of carcasses have been found.
