Unidentifiable IMO but not Western

Probably a Tufted Titmouse

Both barn

Yes, Wood Thrush

With the banded tail this is probably a Red-shouldered Hawk

House Finch

This looks fine for Mourning Warbler. Connecticut is a chunky warbler, perhaps the most chunky warbler, in fact. Thick pink legs rule out any smaller warblers, and shape, lack of eyering, plus the fact that there's only one record of Connecticut in the county rule that species out. @Birds are cool what field guide are you using? If none, I'd highly recommend the Sibley guide. It feels like you're looking at images of the birds without having experience in the field with these species or viewing the key features from a field guide, but this can be misleading as it won't always be obvious what to use as a field mark. For instance, bill color is not useful here. I'd also consult the range map to know what birds are expected.

No lol, I'm not

Yes, depending on the type of bird, varying quality of photo will be required for an ID. In this case, we would need a better photo for an ID. The mark of a good birder is the ability and humility to admit when a bird is not identifiable, as opposed to being able to identify every single one.

Not so.

Both are Pewees

Based on?

Frankly these are not identifiable.

The first bird is definitely not a Mourning Warbler. The second is a Northern Parula. Both Connecticut and Mourning Warblers are chunky, secretive birds, rather unlikely to hang out in the canopy of a tree.

Focus on getting better looks at birds in the field, and guiding ID based on what is expected for that location, at that time of year. It may be technically possible to get an ID from a shot like this, but sometimes you just have to let a bird go. In this case, I personally don't know if I could rule out Blue-headed Vireo, and I'd definitely not add it to an ebird report from this photo alone

This is not identifiable but it's almost certainly not a MAWA. Exceptional birds require exceptional documentation

Most likely a Chipping Sparrow, IMO

This sounds completely fine for Marsh Wren. You can tell it's coming from a small bird- it is just way too high pitched for any rail

Yes

Left foreground bird is clearly a WRSA. I don't see why right foreground bird is not a SESA.

It seems as though you have your mind made up, but for what it is worth Osprey are very common in the Vancouver area, as you can see from this map. The smaller bird is simply not a Bald Eagle, which has a large head projection and very broad wings, unlike the long, slender wings of this bird and the relatively small head.

Rusty is also a bird of wet areas. Think forest floor, creeks, marshy areas. From a behavior/location standpoint it doesn't make much sense for Rusty

First and third are semisands

Wood Pewee

Traills Flycatcher
