A juvenile Oriental Ibis Threskiornis melanocephalus (accidental in Japan) was observed at a Little Egret Egretta garzetta roost in Nara City between February and June, 1983. On 16 out of 19 occasions, it landed on the pre-roosting site before roosting, roosted and departed from the roost together with the Little Egrets.
