Species Directory
Browse tree, flying and ground squirrels, then open a species profile for scientific name, range, habitat, physical traits and conservation information.
260+ species profiles are available in the current directory.
SPECIES · BIOLOGY · BEHAVIOR · NATURAL HISTORY
Learn
Explore the squirrel family from two directions: identify the animal through the species directory, or start with a subject such as behavior, diet, habitat, adaptations, communication or research. Learn is the natural-history side of SQRLFather; practical intervention stays in Guide.
HOW TO USE LEARN
Start with an animal, a question, or a claim you want to check.
The library is intentionally layered so you do not need to know a scientific name before you begin.
Subject Guides
Use Behavior, Wild Diet, Habitat & Adaptations and Case Studies when your question is about how squirrels live rather than which species you saw.
Myths & Sources
Myths & Misconceptions separates common claims from supported information, while Sources & Organizations explains where the reference material comes from.
Move to Guide for practical care
Learn explains squirrels. Guide handles rescue, rehabilitation, long-term care and legal questions where bad advice can create real harm.
