I found a beautiful yellow swamp warbler, aka PROTHONOTARY WARBLER at Deer Run Forest Preserve.

Directions to park: River Road out of Cherry Valley south a few miles

Location of bird: Take the trail that heads through the field off the horse trailer parking area and go right. Continue along the path by the prairie and farm field to the east, looking for SAVANNAH SPARROW along the way. Stay right when the path splits and you’ll still be by the farm field (not forest preserve property). Here I had a LARK SPARROW.

Next the trail will curve to the left after a ways and then split again - go left. I had two singing OVENBIRDS here. Just follow this until the path is flooded completely with running water.

Great day to be out! Several new birds for the year for me!! Also had a Northern Rough-winged Swallow along the river by the parking lot.

UPDATE: Forgot to add that I had my first of year Gray Catbird as well.
