I fear the term ex situ intensive management in the Americas is somewhat different than is the norm in Europe's EAZA/EEP. I just - do hope - AZA may eventually follow this lead.How come the black-cheeked lovebird, agapornis nigrigenis, population is so low ? Not many pure birds available or just a lack of interest? In Europe there is quite a healthy population both in zoos and private hands. And growing the population from 29 to 75 individuals in 5 years is pretty conservative. If you have 14 pairs you can surpass that in one breeding season. The breeding success in colony is lower than when housed as single-sex pairs but still. And the species is attractive, can be combined with softbills and is endangered.
What I find most disconcerting is that this inventory shows up the AZA zoo community seems to hold common non-endangered and quite hopelessly numerous in number psittacine species like budgerigars, cockatiels, galahs in high esteem. Where these take up valuable space that coulld be dedicated to endangered species and ex situ conservation breeding programs and even content to not invest in endangered species and let their populations in AZA zoos go to waste to the point the contestation is ... "we are not being successful..., there is little interest shown by zoos ..., ... we put the endangered taxa on phase out".
I just find that going to the guttural of why zoos actually exist in these modern times .... It seems the whole community just content to sit back and let it lie, which is just mindboggling and incredible to contemplate. This, This, This ... is really the raison d;etre for zoos in this world of ever decreasing biodiversity and more and more species and percentages of whole groups becoming threatened, endangered and potentially going extinct (for example: lesser sulphur crested cockatoo or Cuban Amazon).
