Boogle is the collective noun for weasels.
A Boogle
[1]is most commonly formed during the mating and whelping seasons as weasels tend to be solitary animals; even then, reproductive pairing and boogle formation is usually temporary. Females may be bred by more than one male however mating is restricted entirely within a females native boogle. Mating typically occurs in mid- to late summer.
Fertilization of the ova is followed by a period during which the eggs do not implant in the uterus. No development occurs during this period. This process is called delayed implantation. After 6 to 7 months the fertilized ova implant in the uterus and embryos begin to develop. The total gestation span is 8 to 10 months by which time the majority of boogles will have disbanded.
Young weasels remain in the den for 30 to 45 days, at which time they are about two-thirds grown. Within the den infant weasels appear to form boogle-like groups, however this is a common misconception as female infants have yet to enter menarche and do not display the oestrogen driven behaviour characteristic of a boogle.
After emerging, they stay near the home den for a week or two before beginning to accompany their mother on foraging trips. At 80 to 85 days of age (early fall) they reach full size. At this time, they disperse away from their mother's home range. Sexual maturity is reached by the following spring at which time the foundations for boogle formation are being laid for the following mating season.
