@Dr. Loxodonta They were held in the Tsavo aviary, and if I recall correctly, this is where the species has been put back into upon its reopening alongside the new 'Heart of Africa' exhibit. According to the animal inventory from the zoo at the end of 2022, when this photo was taken, the zoo held 1:1 of the species. The most recent animal inventory from the end of last year, shows that the zoo holds 2:3 Bruce's green pigeon.
