The sparrow is a juvenile White-crowned sparrow.
I saw one today as well.
The last shot could be a juvenile Tennessee warbler, or even
a Ruby-crowned Kinglet. The kinglet has a white eye-ring while
the Tennessee has much less white around the eye. The breast
seems dark, darker than a Kinglet, but it is hard to say from
your photo.
I may have seen a Tennessee in the Rouge today but it was such
a brief sighting that I couldn't make a definitive ID.
Did see RC Kinglet, GC Kinglet, E.Phoebe, WT sparrows, Song sparrows
Brown Creeper, Blue Jays and a dependably Cardinal.
