Mamby on the Beach, the beach-front music festival scheduled for Chicago’s Montrose Beach in late August has been cancelled this week due to discovery of Great Lakes Piping Plover shorebirds who are federally protected species. A pair of the rare birds have made their home on the fest’s location. This is believed to be the first time Plover birds have nested in the Chicago area in 60 years. Two specific birds have been reported in the area for months now by the Chicago Sun-Times, and a few eggs have hatched there earlier this week.

“Despite working tirelessly with the Chicago Park District and U.S. Fish and Wildlife Services to find a new location, moving the festival at this late a date, while still providing a superior beach event experience, would be impossible and a disservice to fans and artists alike,” organizers of Mamby on the Beach said in a statement ran by Consequence of Sound. 

On July 12th, another nature related issues was reported to be contributing to the cancellation by ABC 7 who stated this year’s summer season water level were too high on Lake Michigan for the festival site.

Refunds to ticket holders of this year’s Mamby are expected to be processed within in five to 10 business days. This year’s planned Mamby lineup included BROCKHAMPTON, Phantogram Santigold, Troye Sivan,Sylvan Esso, and more.
