1.3 Indicator brief description
Common tern annual diet and productivity at seven Gulf of Maine colonies managed by the National Audubon Society’s Seabird Restoration Program
1.4 Indicator visualization
GOM common tern average productivity (fledglings per nest) across 7 colonies has varied over time. The pattern is similar to that observed for fish condition (high before 2000, lower 2001-2009, higher/variable since 2010. Productivity is affected by both food and predation mortality. While data on predation is lacking, productivity lows in 2004-2006 were associated with the abundance of euphausiids, and the 2018 productivity low with butterfish in tern diets. The presence of butterfish in tern diets reflects the extension of this warm water species into GOM. Due to their thin, deep body form, butterfish are often difficult for small seabird chicks to ingest and swallow, causing chicks to starve and/or parent birds to increase foraging effort. 2020 was a challenging year for terns raising chicks. While diet composition was similar to the long term average, the quantity of food readily available was apparently less than normal, particularly around the time of chick hatching. This may have been confounded by cold, wet weather when chicks would normally be close to fledging in mid-to-late July. Anecdotal observations showed that feeding rates were low at both those times.

2.1.3 Are methods clearly documented to obtain source data and calculate indicators?
Yes
2.1.3.1 Can the indicator be calculated from current documentation?
Raw diet data were used to create time series of mean shannon diversity through time and across study sites using the vegan R package (Dixon 2003). Code for this calculation can be found here. Diet diversity is presented along with nest productivity (+/- 1 SE).
2.1.4 Are indicator underlying source data linked or easy to find?
Please email dlyons@audubon.org for further information and queries on this indicator source data.
2.1.4.1 Where are source data stored?
Common tern diet and nest productivity data were provided by the National Audubon Society’s Seabird Restoration Program.
2.1.4.2 How/by whom are source data updated? Are future updates likely?
Don Lyons, dlyons@audubon.org

2.2 Indicator analysis/testing or history of use
2.2.1 What decision or advice processes are the indicators currently used in?
Seabird breeding colonies in the Gulf of Maine (GOM) are monitored and managed to promote recovery of formerly harvested seabird species. Common terns are well-monitored and are considered good nearshore ecosystem indicators due to their wide distribution and generalist diet. Common terns breed on islands throughout the Gulf of Maine, feeding on a wide range of invertebrates and fish including Atlantic herring, juvenile (mainly white) hakes, and sand lance. As surface feeding birds, terns are sensitive to vertical distribution of prey as well as nearshore conditions in general, with a foraging distance of 10-20 km from a nesting colony.
2.2.2 What implications of the indicators are currently listed?
Declining productivity across multiple common tern colonies in the Gulf of Maine may indicate changes in the distribution, quality, and quantity of prey over time.
2.2.4 Have the indicators been tested to ensure they respond proportionally to a change in the underlying process?
No
