Not saying I disagree, but we have traditionally accepted field sketches, which have the same issue, as verifiable evidence.
Field sketches are accepted. It should be one you made while observing the individual that the observation documents. Please don’t add drawings from memory or drawings of photographs of the type of organism you think you saw.
Another relevant thread by @david99:
When identifying organisms (mostly birds, for myself) I sometimes come across observations where the photo itself is unidentifiable (due to distance or camera limitations), but the notes associated with the observation add some insight into the probably ID of the organism. Sometimes the photo is just a landscape photo, with the notes that the organism in question just flew off, and a brief description of the organism.
Should identifiers take these notes into account when identifying organisms?
