Description

The Golden-shouldered Parrot (Psepholus chrsoterysius) is an endangered species endemic to Cape York, Queensland. This bird has particular significance to the Olkola People, an important totem, called Alwal in language. Bush heritage have been working in partnership with Olkola rangers for the last 5 years to protect and recover this endangered species. Alwal has particular nesting habits; it nests in specific chronical termite mounds constructed by Amitermes scolpulus. The Parrot is very particular in mound choice, only selecting those of certain size and width (170cm height to 70 cm width). This is believed to provide optimum incubation temperatures. Nest success is also thought to be reliant upon a symbiotic relationship with an Australian mallee motth (Trisyntopa scatophaga) which feeds on the parrots droppings and therefore keeps the nest clean, preventing risk of infections. This study eill assess nest chamber and ambient temperatures and humidity across the breeding season of 2021, using Hydrochron humidity and temperature loggers (DS1923), which will be placed inside and outside selected nests. FLIR heat sensing cameras will also be used to take pictures of all active and non active nests and their nearest neighbours. The data will be compared to early nest research carried out by Weaver (1986) who assessed nest temperatures in the 1970s. This study will provide insight into nest chamber thermal changes, and create a more reliable baseline longer term, due to the technnological constrictions when this study was first carried out in the 1970s.
