Vertebrate (Inventory)/Bat Scratches
From LagWiki
The Bat Scratches field should be used to record stations where noticeable scratch marks left by bats are found.
Claw and scratch marks may be observed indicating that a bat may have roosted or rested there. These marks are rare but may be found on soft materials like gypsum or corrosion residue. Look for them if there are any signs that bats may have been in the area such as guano or bones. If stains are observed (usually on the ceiling) these should be inventoried as other.
