When are Mule Deer Fawns born?
Here in Northern Arizona, we have a rainy
season referred to by locals as the Monsoon Season. This year and last, it began about the first week of July and lasted until the end of July. Just coincidentally, this is the time when most of the fawns are born. In other areas, fawn mule deer may be expected to be born about the first week of June. I have seen several does this week, that look like they are about ready to pop, but still haven’t shed that excess weight.
When I moved to Arizona, I expected that fawns would be born much earlier – even April. This assumption was based on the, apparently, false logic that the further south you go, the earlier spring arrives. The earlier the spring, the earlier the fawning season. Now the question that might be on your mind is – wouldn’t the breeding season have to be later?
In order for fawning to occur in late July, breeding must occur in late December – early January. Because winter doesn’t get serious until that time period, mule deer don’t have much cause to congregate. Breeding doesn’t occur until bucks and does get together. During the summer and even into late fall, mule deer in this part of the world are spread as thin as the hair on top of my head.
That’s my twist on when fawns are born and why. Pay attention and see what you observe.
