A large canvas of my bear photo hung in the BC Legislature. Our local MLA claimed it helped pursued the Premier to totally ban Grizzly Bear trophy hunting in BC. Keep shooting photos, they can make a difference !

I sent this photo to a Forest Service friend who along with state and federal biologists were able to trap and collar her. She is the first female grizzly to be collared in Washington State. I have (trail camera) photos from the following year of her two cubs in my other observations.

Drama. These guys all normally get along pretty well, but here a squirrel decided to start something and nearly got kicked in the head as reward. Moments later they were back to munching sunflower seeds side-by-side again.

I managed to catch the moment where two Juniperus virginiana pollen grains' intines expanded and ruptured their exines. I think the first probably helped trigger the second. Check out this paper for more on the mechanism at work here.
