Résumé :	In our rapidly urbanizing world, species utilizing anthropogenic resources would have positive population trends more than others, although its effect might depend on their ability to cope with environmental change. We tackled this issue using a phylogenetic comparative analysis of hirundines (Aves: Hirundininae). We found that species nesting on buildings, on average, showed more positive population trends than others but, population trends of species nesting on buildings decreased (and even becoming negative) with increasing tail fork depth—an ornament that makes species susceptible to environmental change. Utilizing anthropogenic resources might deteriorate population trends of swallows with deeply forked tails.
