| Much of Portugal's work has focused on [[Bird flight|avian flight]] and [[aerodynamics]]. His research has shown how birds fly in [[V formation|V-formation]], using [[Northern bald ibis]] (''Geronticus eremita'') that were part of a European reintroduction scheme. His team has worked extensively with [[Homing pigeon|homing pigeons]] (''Columba livia''), demonstrating how individuals compromise on speed to stay together as a flock, and the increased energy expenditure required to fly as a group. | Much of Portugal's work has focused on [[Bird flight|avian flight]] and [[aerodynamics]].

| Other work has focused on the eggshell collection at [[Natural History Museum, London|The Natural History Museum]], where Portugal is a Scientific Associate, demonstrating how eggshell properties have evolved.
