Gorillas enjoy Mother's Day picnic at London Zoo

Twenty eight-year-old Effie and Mjukuu, 22, enjoyed a number of healthy snacks alongside their respective children - Gernot, five, and six-year-old Alika.

The zoo would normally be welcoming many happy families on Mother's Day on Sunday (March 14), but the coronavirus lockdown has meant it has been closed for much of the last 12 months.

The closure has caused financial difficulties for zoos up and down the United Kingdom.

ZSL (Zoological Society London) has asked the public to make donations or book future tickets so that they can continue to feed and care for the animals until they can reopen their gates.
