Here are some potential Evidence of Presence values I’ve been thinking of adding, let me know what you think (but please be constructive). Each one shows the value, the applicable taxa, a possible definition, and examples of evidence for which it might be used.
Construction (Animalia) - Something built or excavated by an animal’s non-feeding activities.
Covers: nests of all kinds, burrows/tunnels, bowers, spider webs, ant hills, termite mounds, beaver dams, spider trapdoors and turrets, reefs/coral structures
Evidence of feeding (Animalia) - Evidence that an animal, which is no longer present, has fed. [kind of an ugly sentence…], mosquito bite
Covers: bites marks in leaves, kill sites, woodpecker holes, beetle galleries
Gall (Insects, Mites, Fungi, Bacteria…) - abnormal plant growth instigated by a parasite.
Covers: galls
Scratch or rub (Mammalia, or maybe just some mammal clades) - damage caused by rubbing or scratching.
Covers: bear rubs and scratches, deer rubs, etc.
Leaf mine (Pterygota) - feeding tunnel within a leaf.
Covers: leaf mines
Hair (Mammalia) - hair no longer attached to an organism
Covers: mammal fur
I still go back and forth about construction - the idea is to not use a bunch of different English terms (eg nest, burrow, web, bower, mound, hive, etc) that might be difficult or impossible to translate, but still have term that’s useful when going to a taxon’s photo browser (eg a bunch of web photos for a spider family or genus could be really helpful with ID).
There’s also some overlap, eg a leaf mine could also be evidence of feeding, but having those both be marked doesn’t seem like it would cause many problem (even though I’d be for marking only the best one).
