Correct me, if I am wrong:
Bristol Zoo: 0.1
Colchester Zoo: 1.1 - breeding, unlucky with offspring twice (2017, 2018), new enclosure (due to sand impaction I assume with raising the offspring)
Edinburgh Zoo: 1.1 - new female born 2013 at Marwell
London: 1.1 - nothing recent to jump out over?
Marwell: 1.0 - female passed away in April 2019.

Colchester currently have 1. 2, a female calf was born in May
