Initially, the female goes looking for a mate and commonly lures the buck back into her territory before mating. Depending on species, the rut is an important part of the mating process, even if there are no does involved. Breeding dispersal, defined as the net movement between successive breeding sites, remains a poorly understood and seldom reported phenomenon in mammals, despite its importance for population dynamics and genetics. Roe Deer Behaviour. There are several practical implications of this reproductive phenomenon; (Mammals of Texas).

Reproduction Overall, it is unclear why mating takes place so many months before. In large herbivores, females may be more mobile during the breeding season, undertaking short-term trips (excursions) outside their normal home range. are also short day breeders and are polyestrous. October is their most active breeding month. limiting the amount of GnRH and subsequently LH, that are produced to levels that do not support estrus. cue used to time the breeding season (Lincoln).

The transition into the breeding season is characterized by “silent ovulations” (i.e., ovulations not preceded by overt estrus) and short-lived (8–10 days) corpora lutea in most species studied. Less daylight triggers an increase in a buck’s testosterone, which causes antler Roe deer are the only species of deer to exhibit this trait. Journal of Ethology 22 , 167–173.
