Dear Mr. Yong-Chang Jang, Warm greetings from Busan. Finally, I heard back today from David James, the well-known Australian expert on frigatebird identification who earlier confirmed Korea's first Great Frigatebird record. Based on the single image, he wrote that he believes the Jeju 2007 bird most probably to be a first calendar year (juvenile) Great Frigatebird. While ruling out Lesser Frigatebird, he cannot 100% rule out an unusually plumaged Christmas Island Frigatebird (a species recorded VERYrarely as far north as Japan, therefore being very much rarer in Japan than either Great or Lesser Frigatebirds which are both recorded annually there I believe). Are there any more images of the same Jeju frigatebird to check the pattern of the belly patch and dark breast band? With best wishes and birding, Nial Moores Birds Korea PS His email was as below: I¢®¯m pretty sure this is a juvenile (1st yr) Great Frigatebird. The lack of axillaries spurs eliminates lesser and most but not all CI. The shape of the belly patch is then the only thing left that is visible. Although not strictly ¢®¢çoval-shaped¢®¯ it is rather ¢®¢çcurvy¢®¯ especially bordering the breast band. CI tens to have straighter lines and better defined angles at the front of the belly patch. Nevertheless, the angle of the photograph is not ideal for judging this. Thus most likely a great, possibly but unlikely a CI frigate (at the conservative end of the scale [i.e. with a great-like belly patch and no spurs]) caught at the wrong angle. 1³â»ý Å«±ºÇÔÁ¶°¡ °ÅÀÇ È®½ÇÇØ º¸ÀÔ´Ï´Ù. °Üµå¶ûÀÌÀÇ Èò»ö µ¹ÃâºÎ°¡ ¾ø±â ¶§¹®¿¡ ÀÛÀº±ºÇÔÁ¶´Â Àý´ë ¾Æ´Õ´Ï´Ù.
