Nest-building by hominid apes is learned by infants watching the mother and others in the group, and is considered tool use rather than animal architecture.

Animal geography "Critical Animal Geographies: Politics, Intersections and Hierarchies in a Multispecies World", and Wilcox and Rutherford's "Historical Animal Geographies". There are presently nine areas of focus within animal geography: 1. "Theorizing animal geography". Two major works addressing how to think about human-animal relations as a whole are Whatmore’s Hybrid Geographies, Hobson’s work on political animals through the practice of bear-file farming, and new scholarship that look at animals' relations with the material world. 2. "Urban animal geography". Researchers in this area seek to understand that cities are, historically and today, multi-species spaces. Theoretical work comes from Wolch et al. on what
