It's that time of year. Across most of the United States ungulates (deer, moose, elk, antelope) have either dropped their young or are about to.
The reason they all do it at the same time is because this is also the time of year when all the predators eat as many babies (fawns and calves) as they can find. Nature causes all the animals to birth at the same time because with so many other animals being born the chances of one individual deer being eaten is lessened. Nature is flooding the zone, so to speak.
Young fawns are too slow and small to run away from predators, so nature has given them other defences which mostly work. See the spots? That's deer camo, and you'd be amazed how well it works. Ordinarily deer don't pose in tall green grass, more than likely in some thicket of old brush and leaves. Nature also gives young deer almost no scent so they are hard to find. Mother deer eat all the remnants of the birthing and any excrement from the offspring, they leave nothing that might give off a scent.
The milk of the deer is extremely concentrated so that the young can get all the nourishment it needs while being nursed as seldom as possible. Predators watch the movements of the mother to try to see where the young are hidden. Predation is usually a matter of chance for wolves, coyotes, and cougars, the bear however has an extremely keen sense of smell and bear often account for the majority of fawn or calf mortalities in the first couple of weeks.
Every year many well meaning but uninformed people see young deer, and assuming the lack of a mother means the deer has been abandoned, take it upon themselves to take a deer home. What they are really doing is killing that deer, they just don't know it yet. Deer are good pets for a few days only, then they become a nuisance, they become more problematic not less as a puppy or kitten might.
It's usually about this time that the fawn gets brought to the State Division of Wildlife whatever it is called in the particular state. It's also at this time that people learn that they've broken some kind of serious laws. If they've crossed state lines the laws are even more serious. Of course no one is ever charged or arrested, they meant well.
But then there is the issue of the deer. When the people leave and go home probably in more cases than anyone would like to know the deer is euthanised.
If you care, leave it there.
Update/thanks for the rescue: more eyeballs means more chance someone might see this and leave wildlife be, no matter how tempting it is to rescue it. State Departments of Wildlife are often strained budget wise.
