We test whether stable isotope analysis can identify recently escaped or released captive lorikeets within wild populations, informing management along different stages of the pet-release invasion pathway. https://www.oliverstringham.com/publications/feather-forensics-parrot-origins/ Tue, 01 Apr 2025 00:00:00 +0000 https://www.oliverstringham.com/publications/feather-forensics-parrot-origins/ Wild-caught parrots are sometimes laundered into trade as captive-bred. Using a citizen-science campaign that collected thousands of feathers from wild and captive birds across South Australia, we show stable isotope analysis can distinguish captive from wild origin with up to 90% accuracy in galahs and 74% accuracy in other parrot species.
