Spotted nightjar Eurostopodus argus

Small, widespread nightjar of drier inland areas, from woodlands to deserts. Fairly common in inland Australia. Primarily gray-brown with reddish-brown collar and extensive spots and barring. In flight, all-dark tail and prominent pale spots on outer wing visible. Most commonly seen when flushed from road at night. Song is an eerie wail that ascends in pitch and finishes in crescendo.
