No deer biologist here, but I have always thought a doe's ovulation only occurred once a year (unless not successfully bred), that would be what we call the rut. If true, that would suggest no monthly hormonal cycles like you would see in humans. If no ovulation, then there should be no or little estrogen/progesterone changes. If there were to be more than one ovulation then breeding could occur at any time.


Although does do come into full estrus at the time of "the rut," and will cycle back into estrus monthly until conception, there is some suggestion (some research supports the idea, while some doesn't) that female deer display increased hormone production a month prior to the actual rut. Bucks pick up on this hormone surge and go through a brief period (a few days) of enhanced rutting activity. Hunters who see this peak (which generally occurs at the same time each year) as the "false rut." Some areas experience a very pronounced false rut while others don't. In fact, I've observed false ruts so intense that bucks display far more rubbing and scraping (as well as daylight activity) at that time than they do during the real rut.

Let me also add that I don't think the "false" rut is the cause of all of these cyclical peaks in buck activity. It is just one potential cause. I have seen regional peaks in activity occurring on the same date that are not repeated, and then I've seen both local and regional peaks that are repeated on a monthly cycle all season long. And these cycles are NOT associated with the rut dates (not on a monthly cycle aligned with peak breeding dates). What drives these monthly cycles--and they can be different every year and don't appear every year--is beyond me.

I swear I learn more on this site than I could by reading deer information for hours. Talk about knowledgeable.

Somewhere on your property, there's a little cocker spaniel in estrous. Get her pattern down and you got the makings for some fine Chinese food. \:D
