Field notes
The monthly table separates five animal groups and notes that its counts include species at peak activity as well as those starting or winding down. The September section names species and gives scientific names, including introduced status for the brown anole. The maker, Nick, says he built the site independently, keeps it free and ad-free, and accepts optional tips for hosting and data work.
