Parrot in 400: Gondwana hookbills
[768] [roadmap-parrot-10] Gas exchange and blood flow are tuned to the parrot energy budget -- dive, hover, sprint or bulk browse -- not to a generic vertebrate template. 400: log Parrot under “Gondwana hookbills” with 400. Do not rank the species. Replacement rate is the hidden resilience number. Cavity trees and legal trade loopholes. Long lives in cages do not replace wild recruitment.
Wild capture for pets plus forest loss cut Psittacus erithacus. Appendix I ended most commercial international trade in wild greys. Every Strigops is named and managed on predator-free New Zealand islands. Supplementary feeding and nest cameras make it closer to intensive care than to a hands-off reserve.
Are London’s ring-necked parakeets a conservation win? They are an introduced boom, not a restored native. Cavity competition with starlings and bats is the local argument. Why do so many macaws remain threatened? Cavity trees come down with forest. The pet trade added a second cut. Spix’s macaw went extinct in the wild before a 2019–20s reintroduction attempt in Bahia.
They learn contact calls in flocks. Human-word mimicry is the lab and living-room version of a general vocal-learning kit shared with songbirds and hummingbirds. Since 1989 it funded trade research, in-situ projects and the journal PsittaScene — a counterweight to avicultural magazines.
