Following a number of individual gorilla dispersals from Nkuringo family, a search for their whereabouts was launched in early 2012. It was discovered that one of the former Silverbacks of Nkuringo family, SB ‘Bahati’ who had dispersed earlier was leading a parallel family. Some of the members in this family were former members of the Nkuringo family among other non-habituated members. What started as a follow-up exercise later led to close monitoring of the behavior of the parallel family. The group was later habituated and named ‘Bushaho’ after the topo-name of the locality where the group forages most. Bushaho family is still headed by Bahati and is found in Nkuringo tourism sector of Bwindi Impenetrable national park. Bushaho family is composed of 8 individuals; 1 silverback, 1 blackback, 3 adult females, 1 sub-adult, 1 juvenile, and 1 infant.

Kyaguliro A&B groups are solely dedicated for gorilla research purposes. They are found in Ruhija tourism sector of Bwindi Impenetrable national park. The groups’ habituation began in 1995 following sudden death of the principal family head Rukina succumbed to an electric shock due to lightening on 7th April 2015. After Rukina’s demise, the family was left under the leadership of an inexperienced young Silverback (Mukiza) who was later ambushed by an immigrating Adult Silverback (Rukara) from the Bitukura family, this fueled a split of the family into two – (Kyaguliro A -Rukara and Kyaguliro B -Mukiza) in May 2016 . However this split is not yet assured since the two sub-families continue to forage within close vicinity pausing high potential for re-union or crossing back and forth by some family members. Generally, the entire family is known for spending almost all its time in the inner forest and very rarely gets close to the forest’s peripherals.
Apparently Rukara is composed of 10 individuals; 1 silverback, 2 blackbacks, 3 adult females, 2 juveniles and 2 infants, while Mukiza is also made up of 10 individuals who include; 1 silverback, 4 adult females, 1 sub-adult and 4 infants.

Nkuringo family is also the first gorilla group to record the birth of gorilla ‘twins’ in BINP in December 2004. The group is famously known for foraging outside the park for up to 98% of their time.
