My research is a case study of the effects and interactions between habitat quality and human use of beaches on the breeding territory occupancy of the Western Hooded Plover Thinornis cucullatus tregallasi. This priority 4 resident shorebird is experiencing population decline and is highly faithful to breeding sites, with monogamous pairs returning to the same beach each year to breed. The study area of Cape Naturaliste to Cape Leeuwin in WA is an important breeding area for the species, but the northern portions of this region have an unexplained history of breeding abandonment.
The research seeks to investigate whether abandoned breeding territories differ in some way from those that are occupied. Are food resources poorer? Or is human use more intense on abandoned territories? Are there fewer options for shelter? Or has the physical environment of those territories changed in some way historically? Conversely, if these breeding territories provide equivalent habitat quality to those that continue to be occupied, do these abandonments imply a shift in the regional population stability of this species?
