Cold and wet time of the year
(fertility season) June - July
Makaru is considered the coldest and wettest time of the year. Traditionally, this was a good time of the year to move back inland from the coast as the winds turned to the west and south bringing the cold weather, rains and occasionally snow on the peaks of the Stirling and Porongurup Ranges.
As the waterways and catchments started to fill, Noongar were able to move about their country with ease and thus their food sources changed from sea, estuarine and lake foods to those of the lands in particular the grazing animals such as the kangaroo. As well as a food source, animals provided people with many other things. 'Yongar' or kangaroos provided meat and 'bookas' (animal skin cloaks that were used as the nights became much cooler). Nothing was left; even the bones and sinews were used in the manufacturing of bookas and for hunting tools such as spears.
Makuru is also a time for a lot of animals to be pairing up in preparation for breeding in the coming season.You might now see pairs of 'Wardongs' (ravens) flying together and, upon the lakes and rivers of the South West, an influx of the Black Swan or 'Mali' will arrive to prepare to nest and breed.
Flowers that will start to emerge include the blues and purples of the Blueberry Lilly (Dianella revoluta) and the Purple Flags (Patersonia occidentalis). As the season comes to a close, you may also start to notice the white flowers of the weeping peppermint (Agonis flexuosa) as the blues start to make way for the white and cream flowers of Djilba.
