[I am puzzled...]

agree

[Broad-Winged or Goshawk on the cross-arm?]

Agree and I think the 4th is red-shoulder

 

[Coastal Bird Loon/Gull]

I like the common loon idea - looks like a bit of a white collar. 

[Hummingbird Rufous or calliope]

Seen in my yard in SE BC, Canada. Usually see black-chinned and calliope and I think the tail and wings are about the same length, but this one looks more coppery so wondered if this is a rufous (also here but not often seen in the yard).

Thanks in advance. I love birding!

 

[Yellowlegs]

might have to amend to greater due to the longish bill 

[Yellowlegs]

Looks like it to me. Might be a Lesser Yellowlegs with the short neck. Migration time.

[Confirm immature hooded merganser]

Seen today in SE BC at Waldie Island Trail, Castlegar. Hidden in reeds so lighting poor. Alone. There is a group of about a dozen common mergansers in the river but no other hooded seen. 

Thanks in advance.

[lovely warbler, possible immature Orange-crowned]

Looking again, I think it is a least. Haven't seen one for a while. Thanks

[lovely warbler, possible immature Orange-crowned]

Could be but flitting around in a bush, not behaving like a flycatcher. Will wait for other responses.

[lovely warbler, possible immature Orange-crowned]

Seen today in SE BC. Had seen a Nashville female earlier and several yellow warblers but this one has a yellow covert but darker head and white chest so not sure - immature orange-crowned perhaps? Did not hang around long so this is my only photo.

Thanks in advance.

 

 

[Northern Shoveler?]

Agree, mallards

[Hairy?]

I'm going with Hairy - great debate

[please help with bird ID]

Agree with Western wood-pewee, Western meadowlark and lark sparrow. Any chance you heard the first bird call? Can't mistake the pewee.

[flycatcher in MI]

Saw this bird a few weeks ago in SE Michigan at the WestBloomfield Nature Preserve in a swampy area.  Flycatching behavior and thought it was an eastern Phoebe but the tail is short and beak a bit big and downcurving. Thoughts?

Thanks in advance.

[Bullock's Oriole? South Dakota, last month]

Must have caught it at the edge of its range. I see them often in BC. 

[Whose nest?]

Color looks more robin but rare to have robin's nest on the ground; also I think uncommon for catbirds

[black and white bird help]

Hi all, saw this bird this morning SE Michigan, Heritage Park. Very distant but black (about the size of a red-winged BB) with white back and some around the wings. I think it may be  a bobolink but none reported yet at the park and no yellow patch seen at the back of the head.

Thanks in advance and sorry for the crappy photo but it landed quite distant.

[Morning feeder unknown]

Seen this morning in SE MIchigan. Just can't place it. Help appreciated.

 

[Bullock's Oriole?]

Agree

[Bird with white patches on underside of the wing distal to wing bend]

I considered this, but the wings had more of a V shape and the patch seemed more narrow - like a band vs. splotch. Still could be...

[Bird with white patches on underside of the wing distal to wing bend]

Here in South Dakota near the Nebraska border and saw two birds - bigger than robins but smaller than a Cooper's hawk. Driving so just seen briefly but at 4 pm so had a clear view. Appeared to be grey with very distinct white bands on the underside of the wings as noted above. Tail was fairly long and almost seemed banded. The only bird that I could find that looks like it (and is in the area) is a Common Nighthawk but I have not ID'd it before and this was not dusk. Thoughts?

Thanks in advance.

[Thrush?]

Agree. So much earlier than up in BC.

[sharpie or cooper's]

Saw this bird in SE BC a few days ago. I thought Sharp-shinned based on more rounded head.  But my local expert says Cooper's. Not that I don't believe him, but hoping someone can tell me how to better distinguish with respect to these photos.

Thanks in advance.

[which lovely duck]

Thanks, don't know why this one threw me except that I usually see the females with the males which makes ID easy.

[A few more - Song Sparrow?]

The grayish face and finer stripes on the chest do suggest Lincoln's but I am not seeing a buffy wash. I agree that LBB are difficult, but nice photos.
