Saw this slightly unusual duck with the Scaup flock yesterday - presumably a molting Greater Scaup - but showing signs of both male and female characteristics? A hybrid? Probably not a tufted duck - head shape seems wrong. Or am I just way off base with how weird this duck looked to me?

I was cleaning the other day and found a bunch of old bug corpses that turned to dust at the slightest touch. Photographically, they are not really useful, but I figured I might as well post these here just to help confirm some species. Obviously thes are old dead ladybugs though I am not fully sure they are all the same species due to the spot shapes.

I'm aware of the likelihood of this species in Ontario... Posting this around with the hopes of getting feedback on the ID - more photos & rationale are presented here:

Thanks in advance!

This image is part of an observation I made a couple of days ago, but there was so much going on, including three different avian species, that it merits further comment. Here I am focusing on a juvenile Black-crowned Night Heron (seen in the background) as it peeks out of the brush at a much larger Great Blue Heron, attempting to drive off a Red-shouldered Hawk which has landed on the island. A discarded shopping cart and other assorted trash, washed down the river by a recent storm, adds to the sense of discord, as does the turbulent water boiling in the background. Interesting to note, the hawk remained calmly on the fallen branch throughout the display (which included lots of loud squawking) until the large heron quieted down, before flying off.
So how is this observation about the Night Heron? I simply could not get over the look of that juvenile bird reacting to the conflict.
