Hello Fellow Birders!
What a beautiful weekend for birding!! Today we went down by the Canada Center for Inland Waters along the Waterfront Trail and I was wondering if I could get a little help with a couple of ID's please
I have narrowed this one down to a Grebe, but can't make a final ID:

These two little cuties were quite a distance away:

Another of the pair with their wings flapping:

Not sure if this is one like the ones above or a different one:

Thanks everyone!!
