During 1978 and 1979 over 900 individuals of the mouse‐sized marsupial nectarivore Tarsipes spencerae were pitfall trapped in Banksia thickets on the south coast of Western Australia. In both years numbers were highest in spring, when nectar was most abundant and lowest during summer months when it was scarce. The larger number of males caught probably reflects their greater activity rather than their greater abundance.
