That is a novel idea. I had not at all thought of migration being just about moving from cooler to warmer. That is a possibility but at best a very narrow view. In general it is regular movements of most or all of populations from one place to another. If the birds wanted the warm, they would be sedentary in the tropics. Most of the international or trans-equatorial migrants move to follow the patterns of longer day length. The Arctic Tern, which goes the furthest, by-passes the warmth, to go towards the poles. As for the Friarbirds, whilst position is not always regular, timing of movements generally is.
