is (seen in the male above), whereas the female Rusty Blackbird does have a yellow iris.
Finally, as I posted previously, one of the highlights for me at Comins Lake was American Avocet (Recurvirostra americana). This shorebird is primarily a western species, but I have seen them on one occasion along Lake Michigan at Indiana Dunes State Park. The very smooth looking plumage, white eyering, and upturned bill makes these birds look cartoonish to me.
Other birds of interest at Comins Lake included Clark's Grebe (Aechmophorus clarkii), Pied-billed Grebe (Podilymbus podiceps), Double-crested Cormorant (Phalacrocorax auritus), Great Egret (Casmerodius albus), Great Blue Heron (Ardea herodias), White-faced Ibis (Plegadis chihi), Gadwall (Anas strepera), American Wigeon (Anas americana), Northern Shoveler (Anas clypeata), Green-winged Teal (Anas crecca), Redhead (Aythya americana), Ring-necked Duck (Aythya collaris), Lesser Scaup (Aythya affinis), Bufflehead (Bucephala albeola), Northern Harrier (Circus cyaneus), Sandhill Crane (Grus canadensis), Long-billed Curlew (Numenius americanus), Common Snipe (Gallinago gallinago), Common Raven (Corvus corax), Tree Swallow (Tachycineta bicolor), Northern Rough-winged Swallow (Stelgidopteryx serripennis), Barn Swallow (Hirundo rustica), Marsh Wren (Cistothorus palustris), Mountain Bluebird (Sialia currucoides), and Western Meadowlark (Sturnella neglecta).
