One of John Young's original Night Parrot pics from western QLD in 2013. Used with kind permission.

More happy news about the Night Parrot (Pezoporus occidentalis) today and few people will be surprised that it has again come from John Young. He has found yet another population of Night Parrots, the first in South Australia since Shane Parker and Rex Ellis’ sighting in 1979, and these birds appear to be using samphire (Tecticornia and Sarcocornia spp.).

An update was published on the Australian Wildlife Conservancy (AWC) website this morning detailing John’s work with colleague Keith Bellchambers in the Kalamurina Sanctuary between the northern shore of Kati Thanda-Lake Eyre and the Simpson Desert Regional Reserve. All available details regarding John’s latest work are on the AWC website so I won’t recount it all here except to note John Young’s uncanny ability to locate these birds in the vastness of potential habitat. Sticking to a well-known technique, John located a Night Parrot feather in the lining of a Zebra Finch’s nest. This was after he identified a Night Parrot-like shape in a camera trap image from the same area. The image is barely identifiable as a bird but John’s experience with the bird allowed him the suspicion that the image had several features suggesting the possibility of a Night Parrot.

This find is significant for a few reasons. Obviously, the more populations of Night Parrot that we know of, the better. This SA population now forms a huge triangle of potential occurrence between where the birds are found in central and western Queensland and the birds located in Western Australia. Then there is the isolated Night Parrot signal located by Mark Carter and myself in the Northern Territory. This lies somewhere in the middle of this scalene triangle. That location is also close to extensive stands of samphire. This new site on Kalamurina Sanctuary is choked with samphire. That the birds might be using samphire is not too surprising but this is only the second time John has confirmed it. (He found birds using samphire in Diamantina NP in western QLD but those birds also had access to healthy stands of spinifex in close proximity. There is no available spinifex near to the site discovered by John this time: just lots and lots of samphire.) This is important because samphire is less susceptible to damage from fire. Young plants will not burn. Old plants, while they will burn fiercely, will only do so in large tracts when there is spinifex nearby to fuel a sufficiently vigorous fire-front which can span bare patches between samphire plants (Latz, 2007).

Lake Mackay in NT/WA. Spinifex and samphire in abundance. The mind boggles.

So at Kalamurina John has found birds which can be studied in a very different habitat and with one of their key threatening processes if not totally absent, at least significantly reduced. As always, feral predators remain a possible danger to the birds here but, as with sites in QLD, a healthy population of dingoes is likely to go some way toward minimising the threat posed by both cats and foxes (Ripple, 2014; Letnic, et al., 2011; Moseby, et al., 2012; Newsome, et al., 2015).

Congratulations to John and Keith for another important discovery and all credit to AWC for their continuing great work and their support of Australia’s greatest living naturalist.
