My love for the nature is enhanced by constant education. These are some of the resources that help me classify and learn about the flora and fauna in my photos. I apologise to my overseas visitors these resources mainly relate to Australian wildlife.
https://australianmuseum.net.au/animals The Australian Museum site is an important source of accurate information on classification. Can be contacted by email with photo attachment if you are really stuck. I queried them a few times and they have given good succinct answers.
http://www.ozanimals.com/index.html It is not clear who runs this site but they certainly have a wide array of photos of all animal types with classification. Click on the small index photos to see larger and often a variety of photos. Good to browse through if unsure where to start.
https://fungimap.org.au/ this is a not-for-profit organisation that asks for your sightings of fungus. They have pdf forms to fill in if you want to submit a sighting or have a fungus identified. Identification will take a while as they are inundated with requests and fungi can be tricky shape/colour shifters which are hard to classify. Try some of the resources listed before you submit an identification request.
Instagram I have only recently joined Instagram and WOW! there is every # you could ever imagine. So if you suspect you have a particular fungus, bird, insect search on the hashtag and pictures will come up. I have put in some pretty obscure genus and species names and have never had zero hits yet. From these hashtag searches (and those who like your posts) you can find nature photographers that are also interested in classifying flora and fauna. Use specific hashtags so you attract like-minded naturalists.
http://hunter.lls.nsw.gov.au/__data/assets/pdf_file/0009/516807/guide-to-common-fungi-hcr.pdf This is a guide to local fungi in the Hunter and Central Rivers Region of NSW. Not my region, but of course, a lot of fungi are widespread. Good descriptions and photos.
http://hvbackyard.blogspot.com.au/ This blog appears to be inactive (sadly) for a while. But has a good list of fungi pictures which have been carefully classified.
https://wildlifespotter.net.au/ This is a bit different. Not a site to investigate my photos but a fun site to help with fauna research. Sign up and classify animals taken by automatic cameras set up for various projects throughout Australia. I have spotted quolls, dingoes, white-tailed rats, bandicoots, bettongs, mulgara (small marsupial carnivores) and, I know you won’t believe me – I think a Tasmanian tiger.
Bird apps – Books are still the best tools for bird identification but it can be useful to have a bird app with calls. I purchased the Morcombe and Stewart Guide a few years ago. However this is quite expensive ($30) and really the most useful feature is the audio. I notice there are now free apps for apple and android devices that offer bird sounds.
There are of course many other websites and blogs – some of them specialising in particular types of animals. Image searches are your friend and enemy. I’ve been down a lot of rabbit holes that lead to sites that have no classifications or wrong classification. When doing a search remember to always put the location (at least country) to narrow down. Also remember that juvenile and adult, male and female can look quite different. Observations of behaviour and habitat are also often invaluable in classification.
I have many books on my shelves relating to marine life (from my scuba diving days) birds, mammals, reptiles, plants, and backyard wildlife. Some of these are quite old and there may be better or later editions published. But the following three books I have carefully chosen in the last 6 months and I can vouch for their usefulness in classification (as well as sheer beauty). Books are an important resource and far less likely to mislead you than the internet. They are often my first stop before I check online for more images and details.
The Field Guide to the Birds of Australia, Graham Pizzey and Frank Knight, 2012
I have old editions of Cayley’s and Simpson and Day on my shelves but I was recently gifted this book for Mothers Day and it is my most treasured reference. Each page has only a few closely related species depicted (maximum four) with beautiful clear drawings often showing juvenile, male and female forms as well as variants. Every household should have a bird book and this one I would highly recommend.
The Butterflies of Australia, Albert Orr and Roger Kitching, 2011
Also a mother’s day present. Filled with wonderful pictures of, not only the butterflies, but also eggs, caterpillars, pupae and host plants. This is large book (28cm long) and beautiful enough to grace a coffee table
A field guide to Australian Fungi, Bruce Fuhrer, revised 2016
This is a book with over 500 fungi described and beautifully photographed in their natural environment. It is widely acknowledged to be the most comprehensive guide to Australian fungi. Despite this, fungi identification is incredibly difficult for a beginner like me. Even using this book and internet searches I have five or six fungi photos that have me stumped. There is variation within species of colour and size and many features (sometimes microscopic) that have to be either recorded or photographed. Even in this book there are many fungi that are listed in a general group and described as unidentified species.
