I came across a mini-fallout of passerines at Cone Marsh today. On a loop around the marsh, I stopped at the boat ramp in the NW corner and thought I would make a quick check of the woods since they were sheltered from the wind. There were so many birds I spent over two hours there! Most numerous were ~40 YELLOW-RUMPED WARBLERS, ~30 PALM WARBLERS, and WHITE-THROATED SPARROWS. Also present were LEAST FLYCATCHER, GREAT-CRESTED FLYCATCHER, EASTERN KINGBIRD, YELLOW-THROATED VIREO, HOUSE WREN, BLUE-GRAY GNATCATCHER, RUBY-CROWNED KINGLET, SWAINSON'S THRUSH, WOOD THRUSH, GRAY CATBIRD, NORTHERN WATERTHRUSH, PROTHONOTARY WARBLER (my gosh, is there a more beautiful bird?!), NASHVILLE WARBLER, AMERICAN REDSTART, NORTHERN PARULA, YELLOW WARBLER, WHITE-CROWNED SPARROW, SUMMER TANAGER, and ROSE-BREASTED GROSBEAK. The Yellow-rumped and Palm Warblers were singing but most of the birds were quietly feeding. Near the boat ramp was a SPOTTED SANDPIPER.
Elsewhere at the marsh, in the NW corner a flock of ~225 GREATER WHITE-FRONTED GEESE contained a few ROSS'S GEESE and SNOW GEESE.
From the NE corner of the marsh near the caboose, among the hundreds of distant shorebirds were 12 AMERICAN GOLDEN-PLOVERS and 7 SEMIPALMATED PLOVERS, and also present were a TRUMPETER SWAN, a pair of SANDHILL CRANES at a nest, and along the road a NORTHERN MOCKINGBIRD.
At the south end of the marsh the shorebirds included 39 LONG-BILLED DOWITCHERS. A SORA was heard along the dike.
In Johnson County, a pair of NORTHERN MOCKINGBIRDS was at the traditional field NW of Johnson-Muscatine Ave. and 500th Street SE.
