What lives and visits

Dangar Island?
This project aims to engage and rally the many eyes and ears of people who live on and visit Dangar Island to help learn more about the animals that also live on or visit Dangar Island. The more we know about what species call our island home or like to visit, the better protection we can provide for them.
This is not an exact science - it is a list of citizen data and images - the aim being that we are learning about the needs, behaviour and seasonal changes to the creatures on and around Dangar Island.
The species list is visible on the desktop site only but you can add a species to the list from your phone as you walk about.

Sighting Notes:
For years I have admired the curly light lines on the sandstone rocks on and around the island. I didn't know who made these beautiful drawings until I read that it was the work of the Red triangle slug which lives off a diet of moss, algae and mould. I wondered why the slugs I had seen all go up the Red cedar tree in our garden at night. Years later I read that that they go to the tops of trees to meet other slugs, a place to date and mate. Then, mission accomplished they return to lay their eggs around the tree's trunk. To add to this they are both male and female, haemaphorite, like the Leopard slug. Like the Leopard slugs the Red triangle slugs circle around each other before getting entwined and popping out their genitals to exchange sperm. Leopard slugs do this on the end on a long thick cord of slime that they make to suspend themselves from an overhanging rock or other vertical surface. A great way to ensure there's no interruptions. To protect themselves from predators like frogs, bats, birds or reptiles they secrete a strong super glue like slime that slows down the hunters and allows them to get away.
Australian king parrot
Scientific Name:
Alisterus scapularis
Location:
This mutant King parrot can be seen on our verandah under a large Port Jackson fig tree on the eastern side of Riverview Ave
Date:
December
2022
Sighted by:

Sighting Notes:
Over the years there have been at least 6 or so mutant King parrots on Dangar Island. Maybe being an island we get more mutation happening like the cross breeding that happened a few years ago between the Eastern and Crimson rosellas. The yellow mutant Kings may find it harder to hide from predator birds. Us humans having only 3 types of cones in our retinas cannot see the yellow glowing feathers on the King parrots' wings. Birds have 4 types of cones in their retinas. I wonder how the yellow mutation affects their ultraviolet colour.......Write about your encounter here

Rufous Net-casting Spider
Scientific Name:
Deinopis subrufa
Location:
In the ceiling of my studio on the eastern side of Riverview Ave
Date:
December
2022
Sighted by:
AP

Sighting Notes:
The way the net-casting spider catches its meals is amazing. It will spin a fuzzy web that expands when the net is cast from between its front legs. The spider waits till a cockroach, moth, ant or other insect comes close to its net. It can make special smells to attract the right sized insect meal to it and even places white target marks on its net to help its accuracy when casting its net like rings on a darts board. It is also a multi tasker as it can eat its catch while spinning the next web.
