Not the entire list has been moved on-show, no (though I'm sure that certainly with some of the smaller species I missed some; almost none of the new species were signposted and almost no waxbills were still kept off-show on the 13th).
It is worth noting that in February, many birds were kept off-show that wouldn't be in the summer; not all exhibits in the zoo are able to hold certain migrating/tropical species year-round, and my visit in February probably reflects this a little.
Also, a lot (for the birds at least ~50%?) of the off-show collection were duplicates from the on-show collection, and I'm sure the species list of things moved on-show will probably also contain some duplicates.
I think the actual number of 'new' species on-show might actually be closer to 40 than to 80 (I saw 32 new passerines for the challenge, and can think of about ~10 non-passerines that weren't on-show that are now), but in any case this recent shift of the collection has indeed massively boosted what is visible on-show!
