16 locations were noted for 20+ warbler days:

Hillside Trail, MN Valley NWR

Murphy-Hanrehan

Hok-Si-La Park

Richardson Nature Center

French Park

Rice Lake State Park, Steele County

Gunflint Trail (end of May)

Sucker Lake, Vadnais Heights

Tamarac NWR

Red Lake WMA

Itasca State Park

Sherburne NWR

Kathio State Park

Aitkin CR 18

Myre Big Island State Park

Park Point, Duluth

Only four birders, all in the Twin Cities, mentioned yard lists of 20+ warblers.

An old piece of information states that the state record for warblers in a day is 26, which seems a bit low.  Still true?

Thanks!
