I think these are Great crested terns but I am having trouble deciding between Great and Lesser crested. Confirmation or correction much appreciated.
There were about 7 terns in total sitting on posts about 50 to 100 feet from shore near the Gung Yu temple on Koh Samui.
Thank you in advance
steve

Yes great crested. The photos are under exposed but you can make out the yellowish bill rather than orangey of lesser crested. Structure and crest are other pointers
