Hi all, Tessa Rhinehart, Jack Chaillet, and I birded the Imperial Grasslands this morning. Upon entering King Road Jack called out a female BLUE GROSBEAK from the car. After brief but identifiable looks this bird disappeared into the marshes and brief playback flushed an adult male Blue Grosbeak which immediately started to sing from the leafy tree in the marsh. Photos can be found on our checklist, the link to which is below. Incidentally, Michael David's follow-up to our report had neither male or female adult birds, but an immature male, which indicates that there are at least 3 birds present at this site. While nesting has historically occurred here, BLGR has not recently bred in the county and it would be very cool to see evidence of breeding. Also notable from King Rd. were a Ring-necked Pheasant on the berm on the left after turning from Westport Rd., several very vocal Yellow-breasted Chats, close looks at a Grasshopper Sparrow, White-eyed Vireo, and 5 species of breeding warblers (Blue-winged, Ovenbird, Prairie, Yellow, yellowthroat).
Bobolinks and a Horned Lark were present at the truck stop, and while Henslow's Sparrows were not singing at the west grasslands, they were abundant at the Beagle Rd. area down the road in Washington Co.
Less rare but also of note was a total of around 8 to 10 Green Herons throughout the day, a surprisingly high number for the county.
