Meeting Abstract 54.9  Tuesday, Jan. 6  Protein requirements of seasonally frugivorous songbirds decrease during migration LANGLOIS, L.; MCWILLIAMS, S.**; Univ of Rhode Island; Univ of Rhode Island srmcwilliams@uri.edu Many songbirds are seasonally frugivorous in that they switch to eating primarily fruit during migration and then eat insects or seeds during nonmigratory periods. Previous work suggests that most […]
