Different questions need different sources
A reference is only as reliable as the path from claim to evidence. Different claims require different levels of evidence; websites, anecdotes and research papers are not equivalent sources.
Peer-reviewed primary research is strongest for specific tested claims such as cache memory, gliding aerodynamics or diet analysis. Government wildlife agencies are preferred for current regulations, disease guidance and conflict-management recommendations. Professional taxonomic databases are used for names and classification.
General educational sources can summarize established biology, but unusual numerical or behavioral claims should be traceable to something stronger.
Use current taxonomy
The Mammal Diversity Database, maintained by the American Society of Mammalogists, is a strong checkpoint for accepted species names, higher classification and synonyms.
Older references remain valuable, especially for natural history, but a 20-year-old scientific name should be checked before it becomes the permanent heading of a new page.
Natural history needs multiple evidence types
A species account may combine formal taxonomy, field studies, range sources, museum accounts and conservation assessments. No single source necessarily contains every type of information.
When reputable sources disagree, the disagreement should be shown or the newer source should be identified. Silent reconciliation creates false certainty.
iNaturalist is valuable, but use it for the right job
iNaturalist is useful for occurrence records, community identification context and reference imagery.
An observation photograph supports the observation it documents, not every biological claim about the species. Identification, location and natural-history claims require evidence appropriate to each claim.
Record assessment context
Conservation status is most useful when paired with the source and, where possible, the assessment date or version.
Data Deficient means available information is insufficient for a confident assessment. It must not be rewritten as “probably safe.”
Higher-stakes material needs a higher standard
Husbandry, medical and wildlife-rehabilitation guidance can affect animal welfare. Educational background is separated from action-oriented instruction, with qualified veterinary, rehabilitation and regulatory sources favored for high-risk material.
Individual experience is not presented as a universal medical protocol.
Legal information expires quickly
Wildlife possession, rehabilitation and permit rules vary by jurisdiction and can change. Official wildlife agencies and current statutes take priority over cached summaries.
An unverified jurisdiction should be treated as “Research required” until current official sources are checked.
Unknown is a valid scientific answer
Some squirrel species are poorly studied, especially for reproduction, lifespan or detailed behavior. When evidence is missing, inference from a related species can create false certainty.
Use “Unknown” when available evidence does not support a confident answer.
Keep the trail readable
Reference lists should identify the organization or journal, the source title and a direct route to the source. Longer topics can cite sources by section when necessary.
Quotations should be rare. Clear paraphrasing keeps explanations readable while avoiding a patchwork of copied text.
