Still on the way.
A cold snap has stopped storks on the way back for the summer in Poland in their tracks.

The birds have halted their advance from Africa and are weathering the cold snap in Romania and Bulgaria, researchers reported.

The few storks that have already made their way to Poland are struggling to find food and are getting nearer to human settlements than usual. But storks are equipped to deal with harsh weather and the scientists have asked for people to refrain from feeding them.

The overwhelming majority of storks have, however, been put off by the cold, snow and strong winds.

"They are not far," ornithologist Ireneusz Kaługa said. "We believe two or three days of better weather will be enough for them to turn up."
