[Blue Grosbeak or Indigo Bunting?]

Head,  body and bill size are not correct for Blue Grosbeak... I am all in for Indigo Bunting here.

[Short- or Long-eared Owl?]

Agree with Long-eared Owl here.

[Sharp-shinned or Cooper's Hawk?]

Yes, Cooper's have slightly longer tails than Sharpies, BUT "rounded tail" refers to the shape of the tail when it is spread out -- the tail feathers gradually get shorter towards the outside.  You can't see that in this photo.

You can definitely see the more rounded vs the straight of the Sharpie from the back with tail closed in most cases. The shorter outer tail feathers are only viewed from the underside.   UNLESS, I am totally misunderstanding what you are saying here.

Nothing like a big ol' honkin' monitor.

I really try to not go on ID sites from my phone... for just this reason. Sometimes I need to see the big picture!

[Sharp-shinned or Cooper's Hawk?]

Agree with TBN ... Cooper's here. In addition to the nape, the longer rounded tail.

[Hawk ID.]

Upon looking on my computer tonight... I now see all birds being Sharpies. 

[Sharpie or cooper's]

Cooper's for me as well.

[Peregrine Falcon]

Agree with Merlin

[Hawk ID.]

The think the first looks like an immature Cooper's Hawk... angle making it a little tough. The second is a Sharpie. 

[Female / Immature Indigo Bunting?]

Probably just a 2nd year male or just a late molting male.

 

[A Juvenile Great Cormorant in S VT?]

Agree all DC Corms. 

 

[Veery or Thrush and if Thrush then what kind?]

Agree.. definite Hermit Thrush here.

 

[Kentucky bird sings beautifully!]

That is a Northern Mockingbird

 

[turtle ID]

 Looking again,  it is either a Eastern River Cooter or a Red-eared Slider.

[Could this be a Peregrine Falcon?]

Swainson's Hawk there.

[It's a bird...I think]

Yeah... I am having some trouble with this bird... but I keep coming back to BG Gnatcatcher too.

[turtle ID]

I would agree with Red-eared Slider now seeing the fuller pic. I really could not see much on the other for some reason. 

[Black-bellied Plover?]

Agree

 

[Florida..Corvid? Thrush?]

Boat-tailed Grackle

[Spreadsheet?]

Here is a rough guide of bird frequencies throughout the year in Cecil county. It is from ebird.org...

I am not a turtle expert. But from this picture I think you have a Red-eared Slider.

I'd like to know how you are eliminating some of the Map Turtle species from that limited photo?

It would be much better for ID if you posted the FULL pic in this thread.

I assumed so, but I don’t trust myself enough with thrushes to give a definitive answer.

No worries with that.
