 in Leiden has 2 skins; one male (RMNH 110.061) and one female (RMNH 110.068). Both individuals originate from Philip Island. The male skin was acquired in 1863 long after the species' assumed disappearance, but it is unknown how it came to Leiden. It is more likely, given Phillip Island was already overrun with feral pigs, rabbits, goats and chicken in late 1838, that the 1863 specimen was purchased from another collection. The single unsexed individual from Philip Island at the Zoölogisch Museum Amsterdam http://www.science.uva.nl/zma/ (ZMA 3164) has been obtained before 1860, and originate probably from the same batch as the two specimens at Naturalis in Leiden. An old list of the specimens of birds present in the British Museum of Natural History list two individuals, both from Philip Island. One of the two specimens came from Mr. Bell's collection.
