The authorities in Uganda say the country is experiencing a baby boom among gorillas after five newborns were discovered in the last six weeks.
It comes as they are testing out visits to primate locations, which were stopped due to the coronavirus pandemic
Visits to gorilla nests account for more than 60% of revenue Ugandan earns from its protected areas.
Seven babies have been born since January compared to just three in 2019. It’s not clear why there has been an uptick.
In March, most of Uganda’s tourism sector was shut down due to Covid-19 restriction measures.
But the industry is now slowly opening up. Small groups of visitors are allowed into protected areas as new safety procedures like wearing face masks and social distancing are tried out.
Poaching has been a major worry for authorities especially during the lockdown. In July, a man was sentenced to 11 years in prison over the killing of Rafiki, a popular silverback gorilla.

The first pictures in years of a group of rare gorillas with babies in mountains in southern Nigeria have been released.
Conservationists say this raises hope that the Cross River gorillas are successfully reproducing despite facing extinction.
The Wild Conservation Society in Nigeria, an international non-governmental organisation, said the pictures of the gorillas were captured by camera traps earlier this year.
The Cross River gorillas are said to be the most-endangered gorilla subspecies, numbering only around 300 in the wild.
They were known to live in some mountainous areas in Nigeria and neighbouring Cameroon but are rarely seen.
The recent images of the animals with a number of infants were captured in Mbe mountains, according to conservationists.
The Cross River gorillas are naturally wary of humans and have subtle distinctions from other species - such as smaller heads, longer arms and lighter-coloured hair.
The Wild Conservation Society says it is working closely with local communities and the authorities in Nigeria’s Cross River state to protect the gorillas.

A Western lowland gorilla has given birth to her first baby at a wildlife reserve in Kent.
Gorilla keepers welcomed the new addition to the critically endangered species on 8 January at Port Lympne Hotel and Reserve, Kent.
Phil Ridges, head of the gorilla section, said the mother was being so protective that they still did not know if it was a boy or a girl.
But he said: "We are absolutely delighted. Viringika is proving to be a great mum."
Baby gorillas are born helpless and will initially be carried, close to their mother’s body for several months, until they are old enough to be carried on their mother’s back.
Animal conservation charity, the Aspinall Foundation, which works closely with the park, said these gorillas normally inhabit remote rainforests in Africa and their numbers have been decimated by more than 60% over the last 20 to 25 years.
