Here in Minnesota peak breeding occurs during the week before November 12, regardless of when the full moon occurs. 200 days after that (which is their gestation period) fawns are born - which is about the last week of May first week of June, which is when temperartures have been above 32 degrees long enought that there is new green growth.

I'm not talking about astronomical spring, I'm talking about phenological spring (when new green growth appears). Forget the equinox ... It has nothing to do with breeding or fawning. Deer are on a solar calendar, not a lunar calendar.

If you got it - I'm glad I could help. I'm only here to dispel myths and tell the truth.


Deer do not just see black and white, they are red/green color blind; they see blue, yellow, brown and gray, but not red or green.

Neither female deer nor elk have an "estrus" call or female "in heat" call.

The "chuckle" call of a hen mallard is not a feeding call, it is an "incitement" call (similar to a threat) that often occurs in a feeding situation.


God bless,
