What methods are used to obtain the precise composition of a Yarara's diet for detailed study?

Scat analysis or examining the stomach contents of deceased specimens

Obtaining an exact, granular understanding of what specific species constitute a Yarara's diet requires forensic or direct internal examination methods, rather than relying solely on field sightings which might miss smaller or less frequent meals. The precise composition is typically inferred either through analysis of fecal matter, commonly known as scat analysis, or more definitively by directly examining the stomach contents of specimens that have died from causes unrelated to the study. These detailed analyses are crucial, especially when focusing on species like B. ammodytoides, as they provide specific species identification of mice or voles that might otherwise be overlooked in general observational studies.
