1. Deer

2. Species Just how many species are there? About 90 species!!!
This includes white tailed, black tailed, buck, elk, antelope, reindeer, moose, etc.

3. Deer Diet The Deer family are part of the ruminants.
How many stomachs do they have?
Can you name them all?
Because they are ruminants that means they are herbivores.
Their diet depends on the season
In spring/summer, they eat green plants
In fall/winter, they eat grains, nuts, twigs, etc.
Deer eat mostly in the EARLY mornings and late afternoons.

4. Antlers
What are they?
Antlers are true bone that are grown as extensions of the skull.
In all species of deer, males grow antlers. Some species the female will grow little stubs except for the reindeer.
Most deer species will drop their antlers in the winter time, except reindeer.
SANTA LIED TO ME!!!
Female reindeer keep their antlers until spring when they give birth.

5. Antlers Antlers are re-grown every summer after falling off in winter.
Antlers grow with a spongy tissue covering them called velvet. Before the mating season, the bones calcify under the velvet.
The velvet then is rubbed off leaving the hard bone (antler) exposed.
After the mating season, and a drop in testosterone, the antlers are then shed until the next year.

6. Antlers, WOAH!!

7. Reproduction Male deer are called bucks Female deer are called does
Young deer are called fawns.

8. Reproduction Puberty usually occurs around 16 months of age.
Seasonal changes in temp, rainfall, and day length attribute to when the deer mate.
This means that deer are seasonally poly-estrous.
Short day breeders
They begin to cycle and show estrous behavior in Late September and October.
Most does usually have twins in the spring time after carrying the fetus for roughly 6 months.
The deer live span is on average about 8-12 years.
