I wish I could quote the experts I've read but I think it was from material presented by Fred Bear years ago.

During the Spring and Summer deer are grazers and their scat will be in clumpy masses. During the Fall and Winter they are on browse and will be loose pellets that are so familiar. Elk will be similar but are more grazers than browsers.

Size of the droppings to my way of thinking are less important that the size of the pile of scat dropped. I'll leave the sex judgment ot others.
