Cover image: Thousands of nomadic banded stilt (Cladorhynchus leucocephalus) at an ephemeral desert salt lake in Western Australia. This flock contains a satellite-tagged bird which had just completed a >2,200 km cross-continental flight in <2.5 days. Satellite tracking reveals that banded stilt move to and from inland desert salt lakes in response to unpredictable rainfall, with extensive, rapid and synchronized movements used to exploit ephemeral wetland resource pulses across the stochastic Australian desert (see Pedler RD, Ribot RFH & Bennett ATD. 2014 Extreme nomadism in desert water birds: flights of the banded stilt, http://dx.doi.org/10.1098/rsbl.2014.0547; article due online 22 October 2014).
