This is seriously cool. Don't have a personal expert to guide you in the field? Even if you have, it would be hard to find a better learning tool for the wild life around your home. Whatever you're in to; plants, birds, fungi, insects etc., you will find a very keen and supportive community on Inaturalist NZ.
iNaturalist NZ is a serious Citizen Science project. Professional scientists and researchers use iNaturalist NZ data. Get a free iNaturalist NZ account, start taking photos, load them up and learn your stuff alongside the community.
