Yep, the left tree that didn't fall is a Silver Maple. The one on the right that fell is a Tree of Heaven ( a weed that turns into a shifty large weak tree on account of insane growth rate; not even good enough for a tone wood). It produces a stupid amount of seed clusters and spreads voraciously. There's a neighbor with 3 that I warned to remove and now are little trees, but no more than 3-5 years old. Another neighbor has 2 older daughters of my bitch.
