For the lower bird, most thought some kind of woodswallow, or perhaps butcherbird.  It is a Black-faced Woodswallow, one of our most widespread birds, replacing the Dusky beyond the SE corner.  This one was snapped recently north of Balranald.    I came across a half-dozen hunting over low herbland, hovering in stationary fashion at heights up to about 30m, looking for all the world like skylarks in song-flight.
