Species filtering
Seek out specific species

Browse through all species, just a subset or a specific one you are looking for.
Filtering on species also helps keep the amount of content manageable.
Time filtering
Set the max age of observations

When planning a seal safari you may want only the observations of the last few months, while researching warthog expansion could benefit from older ones as well.
Images
Filter on picture presence

Sometimes you just want to see some amazing photos.
You can disable observations that do not have images.
Favourites
Store your best findings

A surprising brown bear near Sognsvann? An irresistible picture of an arctic fox pup?
Store them for easy retrieval later.
