Marigold Lorikeets eat fruit, nectar, buds, pollen, and small amounts of grains and seeds. They can be very loud because calls help them locate their flock. Like other lorikeets, they spend a lot of time foraging for food in Eucalyptus forests and mixed forests. Their tongue has special bristles that spread out like a paintbrush, aiding them in consuming liquid nectar from flowers. The genus name Trichoglossus is derived from ancient Greek terms meaning "hair" and "tongue", reflecting the unique features of their tongues. Due to their frequent interactions with flowers, they play a significant role as pollinators.

 

The population of Marigold Lorikeets is declining due to unsustainable levels of exploitation, particularly for the pet trade. Since their listing on CITES Appendix II in 1981, over 100,000 individuals have been captured from the wild for international trade.

 

Marigold Lorikeets have an average lifespan of 15 to 25 years.
