Behavioural innovations with tool-like objects in non-habitually tool-using species are thought to require complex physical understanding, but the underlying cognitive processes remain poorly understood. A few parrot species are capable of innovating tool-use and borderline tool-use behaviours. We tested this capacity in two species of macaw (Ara ambiguus, n = 9; Ara glaucogularis, n = 8) to investigate if they could solve a problem-solving task through manufacture of a multi-stone construction. Specifically, after having functional experience with a pre-inserted stick tool to push a reward out of a horizontal tube, the subjects were required to insert five stones consecutively from one side to perform the same function as the stick tool with the resulting multi-component construction. One Ara glaucogularis solved the task and innovated the stone construction after the experience with the stick tool. Two more subjects (one of each species) did so after having further functional experience of a single stone pushing a reward out of a shortened tube. These subjects were able to consistently solve the task, but often made errors, for example counter-productive stone insertions from the opposing end, even in some of the successful trials. Conversely, multiple trials without errors also suggested a strong goal direction. Their performance in the follow-up tasks was inconclusive since they sometimes inserted stones into un-baited or blocked ‘dummy tubes’, but this could have been an attention-deficit behaviour as subjects had not encountered these ‘dummy tubes’ before. Overall, the successful subjects’ performance was so erratic that it proved difficult to conclude whether they had functional understanding of their multi-stone constructions.
University museums have been offering a great opportunity to study thematic collections. In zoology, it has been aiding the university biologist to keep safe extensive biodiversity collections from academic expeditions. When appropriately managed, this opens an opportunity for display, research, teaching, and outreach, especially for regions that may not have easy access to government-managed museums. However, Indonesian university museums have been positioned in a confusing situation in which university museums have limited opportunities to serve the main roles of museums. We use Museum Zoologi Sekolah Ilmu dan Teknologi Hayati, Institut Teknologi Bandung (MZSITH-ITB) as a study case. In this paper, we tried to explore the current roles of university museums being served and explore the prospects and challenges for university museums. Concurrent triangulation approach from desk evaluation, visitor analysis, and a semi-structured interview was conducted to see the current roles of MZSITH-ITB and prospects and challenges in the future. In conclusion, clear general procedures to standardize the collection management are urgently needed, so university museums can have a degree of independence to collect and study objects and collections. This can allow easier data integration and specimen sharing in which the museums can work together to shed some light on Indonesian biodiversity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
