And there are a few more species that I should be able to add when they come back on show in summer.
I've got quite a lot of travelling planned for this year but none of it is in Europe so I may not get to another European Zoo until possibly September.
Another species from yesterday that was unsigned but I've just identified (a new species for the zoo)
53) Madagascar Partridge Margaroperdix madagarensis
