Interesting, but this kind of puts the whole study into doubt:

"Since these birds are so highly dependent on weather patterns, as the climate warms in response to human-caused global warming and atmospheric circulation is altered, frigatebirds may have different flight paths in the future, the study notes."

Unfortunately that is something they have to put into most studies these days in order to get funding.
