Three Life Birds - maybe

Since the weekend, I have seen three new birds. One has been positively identified and confirmed by those with more expertise than I possess. The other two I have identified and hope for confirmation from the experts. Otherwise, they won't go on my list.

The positive ID: Swamp Sparrow




Here are the other two that I am almost sure of, but not quite: Northern Parula & Blue-headed Vireo. The pictures are terrible, but it's the best I could do. YES, I am taking a photography class. But I'm still learning. Actually, I think a bigger lens is in order for these little birds :)

What do you think? Are my IDs correct?
