Two species of skinks (Fig. 1) occur in a 5-ha plot on Guam where we have been conducting intensive research on Brown Treesnake (Boiga irregularis) population biology for nearly a decade (Rodda et al. 2007). The Pacific Blue-tailed Skink (Emoia caeruleocauda [de Vis 1892]) is native to Guam, whereas the Curious Skink (Carlia ailanpalai Zug 2004) is invasive. On the evening of 27 November 2012, PML and MSP discovered a pile of vomited skinks (Fig. 2) inside the plot (UTM 55P: 269125 m E, 1508930 m N).
