Hutchinson ? Temperatures that have soared into triple-digits across Kansas this week have forced a large group of egrets into a desperate search for water, killing many and causing problems for locals.

Many of the migratory birds began dying of thirst Wednesday, while others wobbled down the city’s streets in search of water, wreaking havoc for motorists.

Workers for the city are putting up temporary fences to try to corral the birds.

“They’re thirsty and on the move,” said city building official Bob Fairbanks, who called U.S. Fish and Wildlife for advice. “The heat’s the problem. Last night, there were about 250 in the cemetery, where there were sprinklers.”

Temperatures reached 107 in Hutchinson on Wednesday and were expected to reach 109 on Thursday, according to the National Weather Service. The heat wave is expected to break today, with the forecast calling for a high of 94 in Hutchinson and partly cloudy skies.

Kenneth Kessler, an agent with U.S. Fish and Wildlife in Topeka, said he has spoken with Hutchinson officials about the birds several times in the past few months and has given them permission to care for them.

Egrets are protected by the federal Migratory Bird Treaty Act.
