Colchester Zoo have released a news article about their annual animal count. This is the fourth year where the numbers of each animal group have been included.
The number of species in the zoo at the start of 2022 was (with previous years in brackets):
Mammals - 68 (69 in 2021, 70 in 2020 and 72 in 2019)
Birds - 19 (21 in 2021, 24 in 2020 and 39 in 2019)
Reptiles - 34 (unchanged from 2021, 32 in 2020 and 33 in 2019)
Amphibians - 7 (8 in 2021, 2020 and 2019)
Fishes - 47 (55 in 2021, 60 in both 2020 and 2019)
Invertebrates - 9 (19 in 2021, 28 in both 2020 and 2019)
The article about the count is included here:

I must say, it's disappointing to see that, apart from reptiles, every single group of animals has had a decline in number of species held since last year.
One other bit of news mentioned in the article is that there are three crested wood partridges - only two were both visible and mentioned in the zoo magazine a couple of months ago.
