1. Postnatal growth is an important life-history trait and can be a sensitive indicator of ecological stress. For over 50 years, monotonic (never-decreasing) growth has been viewed as the predominant trajectory of postnatal mass change in most animal species, notably among birds. However, prevailing analytical approaches and energetic constraints may limit detection of non-monotonic (or multi-phasic), determinate growth patterns, such as mass recession in birds (weight-loss prior to fledging, preceded by overshooting adult mass), which is currently believed to be restricted to few taxa. 2. Energetic surplus and shortfall are widespread conditions that can directly influence the degree of mass overshooting and recession. Thus, we hypothesize that in many species prevailing energetic constraints force mass change away from a fundamental non-monotonic trajectory to instead follow a monotonic curve. 3. We observed highly non-monotonic, mass change trajectories (overshooting adult mass by up to almost 20%) among ... : Chick growth data from NLME analysisThis file contains data used in the NLME analysis, including 4999 mass measurements across the 313 common tern chicks studied at two sitesin four years.Arnoldetal 2015 JAE NLMEdata.xlsxBrood Provisioning DataThis file contains data used in the LME analysis of brood provisioning rates, including 87 provisioning rate observations across the 36 common tern broods studied at two sites in three years.Arnoldetal 2015 JAE BroodProvisioningdata.xlsxIndividual Provisioning DataThis file contains data used in the analysis of individual provisioning rates vs. mass overshooting and recession, including 15 provisioning rate observations “prior to peak” and across the 36 common tern broods studied at two sites in three years.Arnoldetal 2015 JAE IndividualProvisioningdata.xlsxBird Island 1971 three-period comparisonsThis file contains provisioning data from Bird Island in 1971 used in in ESM 3 to demonstrate similarity in provisioning rate between three different time periods.Arnoldetal ...
