How many babies do deer have at a time? And how do deer communicate with each other?

REPRODUCTION


With good health and good nutrition, whitetailed deer are prolific breeders. Examination of over 600 does in Nebraska has shown about 60 percent breed as fawns (when they are about six months old) and virtually all of the older deer produce young. At least a portion of the buck fawns are capable of reproduction. Breeding commences in mid October and peaks in mid-to-late November for adults, and about one month later for fawns. A buck may mate with several does - up to 20 has been noted under pen conditions. Fawns are born after a gestation period of about 201 days, from early May through late September, with about 60 percent of the total born in June. Does bred when less than a year of age normally produce a single fawn, with 10 percent of them bearing twins. Older does average almost two fawns - 67 percent have twins, 21 percent have single fawns and 12 percent have triplets. This means that about 140 fawns are born for every 100 does in the population.





When one deer senses trouble, it quickly communicates alarm to other group members.





Once the deer is convinced the danger is real, it will flag while dashing for safety. The animal bolts away with tail upright, waving it back and forth and exposing the white underside and rump patch. Hair on the tail flares, making it appear larger than it really is. Deer flag less often in dense cover; where signals are not as easily seen by other deer; then in open country. Vocalizations are not as important as visual signals, but can still help predict behavior. Deer, especially does, sometimes snort when disturbed or alarmed. The short blasts of air made singly or in series are less common than flagging.





Injured deer sometimes bawl, or make an intense, high-pitched, prolonged call. Bawls warn other deer to flee. Deer living in groups may stomp their feet when alarmed to warn others. but foot-stamping can be heard for only a short distance. During the rut, bucks produce two primary sounds. The most commonly heard call is the tending grunt - a low gutteral grunt.





Tail Wagging


Tail wagging is the casual side-to-side motion without hair erect, signals no danger. Similar to tail switching in horses and cattle, it is most commonly seen in warmer weather.





Tail Flicking


Tail flicking is the sharp side-to-side motion with the tail horizontal or upright and hairs erect, signals mild alarm. Tail flicking means the deer has sensed something wrong, but doesn't know how to respond. It may stop feeding and raise its head, or lower its head as if to feed and then jerk up again. If the animal doesn't detect anything, it will probably relax and resume normal behavior. But if the disturbance continues, it will take a flight. A whitetail alerts others and quickly brings its group together by holding its tail horizontally or upright with hair erect, without waving it back or forth. This signal means the deer knows an intruder is close but doesn't know exactly where. Once the deer is convinced the danger is real, it will flag while dashing for safety. The animal bolts away with tail upright, waving it back and forth and exposing the white underside and rump patch. Deer living in groups may stamp their feet when alarms to warm others. But foot-stamping can be heard for only a short distance.How many babies do deer have at a time? And how do deer communicate with each other?
I don't know alot. I believe only one at a time. Two is extremely rare. The only thing I know about communication for sure is if one senses danger they flap their tails up and down to flash their white bums like a warning flag.How many babies do deer have at a time?

With proper nutrition and if their densities are not too high, most does will have 2 fawns at a time. However, this is not too common because in many parts of the US they are either overpopulated and/or in an area where they do not receive enough nutrition to have two.
