Heard the bee-buzz Bronx cheer for 10 minutes before finally seeing the Blue Winged on the powerline. Great looks! Also heard then seen multiple Prairie warblers and a lovely singing field sparrow. A Bobolink (likely on a nest) in field on east side of Marble St. near old shooting area. Saturday heard then seen Black billed cuckoo, also on Marble St. Much to see, two great mornings WRM.
