Some good targets there! @Tanager 101 would probably have a better answer to these, but he might be busy so I guess my reply will have to do until then 😂 Some of these are going to be impossible as you mentioned, a couple difficult, and some pretty easy.
AM Black Duck - usually one or two stick through the summer at Shiawassee or along the coast.
Ruffed Grouse - yeah...there's only one spot I know of about a half hour from Bay City, and no consistent reports throughout the summer months. Might be pretty tough.
Woodcock. They're there! Just not calling as much, so you'd pretty much have to flush one.
Cuckoos. They breed in the area, especially around Shiawassee, but again, they're secretive, so you've got to get lucky.
Whip-poor Will. Really very uncommon in the area. I don't know if you'd be able to go, but they're regularly reported calling at Tuttle Marsh further north in Iosco County.
Herring Gulls should be ez at Bay City Sp. Lots of good photo ops there!
Black Terns - should be a few hanging around Shiawassee.
Common Loon - sadly a bit too far south for breeding birds. Further north you might get lucky, but I'm not sure of an exact location.
Least Bitter - they're there, but as with all bitterns, luck will be required! Might be easier to at least hear one if a night trip can be planned.
We ain't birders if we can't get you an Osprey, Green Heron, Virginia Rail, or Gallinule 😉 Should be pretty easy.
Short/Long Eared Owls are gone in the summer months, sadly.
Eastern Screech-Owls are there, but not calling much. You'll have to get lucky.
Wood Thrush and Veery should be possible with some searching, but most likely will be heard rather than seen.
Marsh Wren and YBSA and pains to photograph, however they will both be easy to find, and with some luck ya might be able to get some decent shots.
Alder Flycatcher - pretty uncommon, but might get lucky and find a singing one.
Prothonotary Warbler - should have a pretty good shot at these on one trail at Shiawassee!
Sadly, the remainder of your warblers are all either too far north or south, or only migrate through in spring and summer. Golden-winged and Chestnut Sided are very infrequently reported, but we might be able to find one with some diligent searching. I wouldn't count on it though.
Broad-winged Hawk. I could be wrong, but these are going to be hard to get. Only place they've been reported (And still infrequently) in the summer is further west in Midland county.
Henslow's Sparrows are pretty rare, with no consistent reports. Grasshopper might be more abundant relatively speaking, but hard to find.
Purple Finches unfortunately are more of a fall-winter-spring bird in that area.
Oh yeah, Ovenbird. A bit more frequently reported than the other warbs, but still going to be pretty tough. Might get lucky at the Chippewa Nature Center or Shiawassee, though.
Rose-breasted Grosbeak-should be pretty easy to find a singing bird or something. Scarlet Tanager is going to be a little trickier.
Bobolink - should be able to get 'em at Shiawassee.
Eastern Towhee - a pain to find in the summer, especially in a kind of underbirded area such as Saginaw/Bay counties. @Tanager 101 might have some local expertise, though.
Whew, hope that helps a bit! Let me know if there's anything else. Hopefully @Tanager 101 has some good tips too.
