A new arbovirus was isolated from ticks of the species A. robertsi collected on 3 January 1980 from trees in which B. ibis coromandus was breeding. The breeding site is located in a swamp at latitude 27�S.,longitude 152"E. in south-east Queensland. Larvae, nymphs and adults of A. robertsi were observed to feed on egrets. The serum of 29 out of 37 egrets from the same colony contained neutralizing antibodies to the virus. No information is available on the pathogenicity of this virus for cattle egrets, or other species of bird. Lake Clarendon virus is suggested as the name for this new virus.

Bubulcus Ibis

Abstract The copulatory behavior of the Cattle Egret (Bubulcus ibis) was observed in a heronry in central Japan. In 38 of 147 extramarital copulation (EC) attempts with seven females, the males seemed in ejaculation. There were relatively few complete ECs prior to egg laying, because females responded aggressively to approaching males and because the mates of the females stayed in the territories for 78.8% of the time and protected the females. After egg laying, the aggressiveness of females against approaching males decreased and their mates spent more time outside the territories, resulting in an increase in the occurrence of complete ECs. Fighting males that were approaching a female exhibited a dominance hierarchy. The most dominant male stayed in the territory for the longest time and copulated most intensively with his mate and other neighboring females. Extramarital copulations are likely to occur in colonial herons, but mate-guarding by the male and aggression by the female mate enhance the probability that copulations will be performed only between members of the pair during the fertilizable period of the female. Thus, the monogamous pair bond is maintained.
