My in-laws lease a farm in Maryland. They've been hunting here for at least 10 years. They mostly hunt bucks but will take does on occassion. They are the only ones that hunt that farm, so it is not over hunted.

In the last couple of years they have been noticing fewer and fewer deer and more and more coyotes. They usually see a few coyotes each time they go.

They have also noticed, that the does they see, arewithout fawns. They have seen as many as 7 coyotes running together. Probably a family group.

My brother-in-law was archery hunting last year and watched as a lone doe came past his stand. As he was watching the doe, he heard leaves rustling behind him. Since the rut was on, he prepared for maybe a shot at a buck. Suddenly the doe took off running as a coyote came running after it, from behind him.

This farm is not overhunted as they only take 3 or 4 deer off of it a year and almost all are bucks.

They scout in the winter and see few deer tracks but coyote tracks are everywhere.
I believe that the reason they don't see as many deer is because of coyotes. i also believe the reason the does don't have fawns with them is because the yotes are getting them.
