Comment | Immature bird. Immatures of all three species of frigatebird are difficult to tell apart. The tour leader said that the Lesser Frigatebird is quite rare on Christmas Island - perhaps only half-a-dozen, whereas there are hundreds of Great and Christmas Figatebirds there. This bird was perched with many similar ones in the vicinity along with adult Great Frigatebirds. The Great Frigatebird is also significantly larger than the Lesser Frigatebird and would have stood out amongst the others if it had been a Lesser. The immature Christmas Frigatebird has a narrow dark band separating the tan head and white breast and so can probably be eliminated. I suppose it was a combination of all these factors, along with a long familiarity with all three species which caused the experts on the trip to have little doubt about its identity. | ||||||||||||||||||
