[A couple flycatchers from today…]

my guess  #1 Agree with Western Wood-Pewee

                  #2 Agree with Pacific-slope

                  #3 Western Wood-Pewee (only because it's posture doesn't seem                          as upright as an Olive-sided) Wait for the experts.

[Flycatcher?]

Your bird doesn't seem yellow-green enough to be a Yellow-bellied.  IMO it's white contrasting throat,chest and belly along with steep forehead and large round crown suggests a Least Flycatcher.

[A little help with these]

I agree with your IDs. The strong chestnut cheek patch on the first bird suggests Cape May and the orange legs on the bird in the last photo suggests Blackpoll.

[Shorebirds]

I originally thought #1 was a Lesser and when Aiden suggested Greater, I had a closer look. It seems to be looking slightly away from the camera, which would make the bill appear shorter and it also looks slightly upturned. I now agree with Aiden.

[Least Flycatcher?]

I believe you are correct. Steep forehead,  bold messy eye-ring,  white contrasting throat,chest,belly,   short primary extention, bold wingbars and short tail.

[Foster's or Common Tern?]

In the first picture the flying birds seem to be Forster's, displaying silver-white primary coverts and gray tails with white outer webs.

[Scruffy Indigo Bunting?]

I think you are correct. Indigo Bunting. Maybe immature male (1st spring)

[Assuming House Finch, but so much red/pink]

Purple Finch

[Various Birds]

Yellow-billed Cuckoo, Common Yellowthroat, Swamp Sparrow, House Wren, Gray Catbird, House Wren, House Wren.   I think.

[Tennessee Warbler? Montezuma NWR central NY 5/3/22]

Looks good for a Tennessee.

[Unknown Warbler, central NY state 5/2/22]

Perhaps a Yellow-rumped (Myrtle)

[Couple sandpipers]

I like Semipalmated and Pectoral.

[Flycatcher...maybe??]

I'll give it a try. My guess is a Willow Flycatcher. Based on slender body,orange lower mandible, indistinct eye-ring, medium bill, dull wing bars and I think I can see medium primary extention. Without hearing its 'fitz-bew' call, it looks very similar to an Alder Flycatcher. I'm definitely not an expert and may be way off base, so wait for an expert.

[Which empid flycatcher? Central NY State 4/30/22]

I agree. Least

[Sandpipers, central NY state 4/29/22]

I agree with your IDs

[Sharp-shinned?]

Thanks. I value your opinion.

[Sharp-shinned?]

I think this is a Sharp-shinned, but with this poor image, should it be reported on ebird as Sharp-shinned/Cooper's Hawk?   Halifax,Nova Scotia this morning. Thanks

["kumlieni" Iceland Gull or Glaucous Gull?]

I think this is a Glaucous. I note that it has the rounded head of an Iceland but, the forward positioning of the eye as the result of the wider rear head points to Glaucous. As well,the white wing tips project less than a bill's length beyond the tail giving the gull a more compact look than an Iceland. Wait for the experts.

[I do believe I have a Juvenile Bald Eagle here... Can you help me estimate age please...]

I think you may have a first year Red-tailed Hawk. Wait for the experts.

[I think I found a Red Knot this morning.]

Thanks for the confirmation Birding Boy.

[I think I found a Red Knot this morning.]

At an oceanside beach in Nova Scotia this morning. Is this a Red Knot? Thanks for your assistance.

[Lesser Black-backed Gull?]

Thanks for the input Aiden. GBBG are far more common here. Young gulls are a challenge.

[Lesser Black-backed Gull?]

On the coast of Nova Scotia this morning. Might this be a Lesser Black-backed Gull?  Thanks.

[Sparrow ID confirmation please]

This morning in Nova Scotia. Savannah Sparrow ( Ipswich ) ?  Thanks.

[confirm ID]

Looks like a Lesser Yellowlegs to me. Shorter straight bill. I'm no expert.
