Agreement on the Conservation of Albatrosses and Petrels

UPDATED, No fooling about on 1 April! Return rate of Short-tailed Albatrosses to Mukojima from the 2008 translocation cohort reaches 60%

It's all go on Mukojima in the Japanese Ogasawara islands.  Two more colour-banded Short-tailed Albatrosses Phoebastria albatrus from the 2008 cohort have now been reported visiting the translocation site where attempts are being made to create a new breeding colony on the non-volcanically active island.

Red Y07 (male) and Red Y10 (female) were seen ashore on the first of this month (April Fools' Day) where they were photographed engaging in a mutual display.  Previously seen Red Y01 was also present.  This brings the number of returned birds from the 2008 cohort translocated as chicks from Torishima to six out of 10 - or 60%.

So far one bird of the 2009 cohort of 15 translocated chicks has returned to Mukojima (click here).

Red Y10 was previously observed and identified from a video photograph that showed its colour band on  4 August 2010 near Seguam Pass in the eastern central Aleutian Islands by Rob Suryan and  a Japanese TV crew.  For another record of a Mukojima STAL seen at sea after fledging click here).
