Hearts: how visitors like an animal.

Every fact file has a heart. Visitors tap it to show they love that animal, and you can see which animals are the most loved.

Steps

On a fact file, the heart sits on the animal's photo, at the top right, with the number of hearts so far.
The visitor taps the heart. It fills in, the number goes up and a few small hearts float out.
A bubble says the animal thanks them, for example “Luna thanks you! ♥”, and shows its place among your favourites, such as “#2 most-loved here”.

Each phone can heart each animal once. The heart stays filled on that phone.
Hearts show on animals, species, films and blogs. Quizzes and audio guides don't have one. On a film the bubble says “Thanks for the heart! ♥”.
A visitor who hearts five favourites earns the Superfan Discovery badge.
On Accelerate, Most loved · all time in your Insights Overview ranks your most-hearted animals.
The hearts a visitor gave are counted on their Share my visit card.
