  1. Hi, I'm at the stage of interpreting my results (after now having produced the beautiful maps). One thing that slightly troubles me is that, for most birds, the locations in Africa either side of the autumn equinox differ. I am wondering if this is real, or an artefact of the equinox. Most of the locations after the equinox are further S, but a couple are N. There is a similar effect for some birds in spring. I tried to insert some examples (lat-lon plot & map), but seem unable to insert pictures (unless they have a URL?) and I am unsure how to upload files (to my "media library") to attach. What are people's thoughts on such findings? Is this a common artefact of the equinox, or might this be a real shift in location? Thanks for your feedback. Louise
