You are right. That looks better. May want to fix the species name, though. Corylus sp. (perhaps Corylus americana)

Looks like a Hophornbeam (Ostrya sp.) but it's hard to tell.

Nice pink coloration, rare up here in the North.

I would it is Scots pine - Pinus sylvestris (an introduced species), based on the two needle per fascicle arrangement, however it is hard to tell without seeing the classic rusty red bark.

Some sort of mole cricket. My best guess is Gryllotalpa gryllotalpa, but that's not a sure thing.

Those look like Japanese beetles (Popillia japonica) to me

Look at the trees above where the photo is taken. They look like branches with fruit attached that fell into the river. Maybe Black Walnuts?

It is entirely possible that it could be a lynx, however, when in doubt, do not assume. The coloration suggests a lynx, but the range of the lynx ends just shy of the Arizona border. The ear tufts and ear spots are not defined well enough to sway me one way or another. Do you have any other photos?

The color of the pattern appears mostly deep red brown and a darker grey, typical of the young western ratsnake. Milksnakes also generally have thicker and more consistent banding across their back, whereas younger ratsnakes have a broken pattern, more spotty than consistent. Both species are found within the same range.

Sometimes Rock Pigeons (Columba livia) develop many variations of color patterns, likely due to their larger population sizes.
