Sightings are other people’s alerts. The Perch sensor triggers alerts based on community intelligence. You can find your own alerts and details in [Perchybana](/perchybana/what-is-perchybana/).
Sightings give you an indication of who else is seeing what you’re seeing, and how they are dealing with the indicators that you’re both alerting on.
Sightings on the Map
The map on the dashboard shows sightings geographically, displaying sightings as a heat map representing the level of alert activity within your communities.
Clicking on one of the colored hexagons1 will open a panel beneath the map with sightings details within that geographic area.
