The vertebrate prey of the Cattle Egret
Ardea ibis was determined from 850 boluses regurgitated by advanced
chicks over 12 breeding seasons from 1981 to 1993, at three heronries in the Lockyer Valley, south-east
Queensland. Vertebrates comprised one species of mammal, 16 species of reptile and nine species of amphibians
and included the locally rare skinks
Ctenotus eurydice and
Eremiascincus richardsonii and Grey Snake
Hemiaspis
damelii. In large numbers were the Cane Toad
Bufo marinus, the native Eastern Dwarf Tree-frog
Litoria fallax
and skink
Lampropholis delicata. Almost 50 per cent of the amphibian and reptilian species recorded for Lockyer
Valley pastures and cultivation were discovered in the Cattle Egret regurgitates.
