Using Samoan traditional ecological knowledge to identify calls of the critically endangered endemic tooth-billed pigeon (Didunculus strigirostris)

Summary Evidence-based conservation can be hindered by limited field data, but historical archives have the potential to provide unique insights into conservation-relevant parameters, such as identification of suitable habitat for threatened species. The Manumea or Tooth-billed Pigeon Didunculus strigirostris has declined on Samoa and only a tiny remnant population still persists, and a key first step for conservation is to locate surviving birds. Numerous Manumea records are available from the nineteenth century onwards, and we used historical and modern records to generate a series of species distribution models to predict the distribution of suitable habitat across Samoa to guide new field searches. Manumea distribution is closely associated with forest cover or its proxies. Preferred Manumea food plants are suggested to be low-elevation trees, but elevation provides relatively low percentage contribution in most models, thus not excluding the possibility that Manumea might occur at high elevations. There is also little evidence for elevational change in records over the past century. Models based on visual versus acoustic records exhibit differences in predicted habitat suitability, suggesting that some purported acoustic records might not actually represent Manumea calls. Field searches should target areas representing high habitat suitability across all models, notably the forested central axis of Upolu.

Traditional ecological knowledge (TEK) or local ecological knowledge (LEK) have only recently gained traction as “legitimate” science in Western academic discourse. Such approaches to inclusivity continue to face institutional, sociocultural, and equity barriers to being fully accepted in academic discourse in comparison to Western-based frameworks. Postcolonial studies have attempted to rectify this Western-domination in characterizing diverse forms of bird–human relationships. However, the integration of multiple cosmologies (worldviews) and ontologies (realities) in research or management creates challenges that we discuss. We elucidate commonalities and antithetical positions between Western-derived bird knowledge and management with that of TEK or LEK in both local and global contexts. We combine ecological/ornithological studies with key terms, theories, and methods from the social sciences to integrate the approaches and facilitate understanding. For example, we follow a “theory synthesis” approach in this conceptual paper to question epistemological and ontological assumptions of bird knowledge and how we acquire it to question, “how do we move from a decolonial approach (discussions and acknowledgement) to decolonization (action)”? This paper is a product of ongoing discourse among global researchers of an academic ethno-ornithology research lab based in the United Kingdom, who partner with global collaborators. The three case studies draw from ongoing research in Southeast Asia, South America, and decolonializing policy efforts in New Zealand. We analyzed these case studies using a postcolonial theoretical lens to provide insights into how Western scientists can embrace TEK and LEK and actively work to decolonize ethno-ornithology and ornithology in theory and practice. Further, we discuss perceived core tenets to equity and inclusion in community-based TEK and LEK conservation projects from the Global South. Diversity, equity, inclusivity, and justice in bird–human relations and knowledge were identified as targets for systemic change within the academic institutions of Western scientists. By recognizing, discussing, and embracing non-Western cosmologies and ontologies, non-Indigenous scientists can help influence the decolonization of ethno-ornithology, ornithology, and bird–human relations through respectful, participatory, equitable, culturally considerate, and “non-extractive” community-based initiatives in partnership with local groups.
