Institution NA
Conditions of use/Licence Open Data, data are available for unrestricted use. However, the data owner asks to be notified when anyone downloads data during his lifetime. Data owner would also like to communicate with anyone who plans to use the data so that he can help with interpretation.
Data available via pipeline No
Quality check of the original data Several QA procedures were used in the field. Detailed QA checks were made during the preparation of the database.
Study site
Name Ram Island
ID RAM
Country United States of America
Size (ha) 1.5
Major site changes Yes. Erosion by storm waves reduced the area suitable for tern nesting by about 20% during the study period.
Latitude 41° 37' 05" N
Latitude 70° 48' 15" W
Number of nests (min) NA
Number of nests (max)

The largest number of nests was about 3,100.
Vegetation Type Scattered herbaceous vegetation on substrate of gravel, cobbles and rocks.
Description of study site Small island composed of glacial till.
Species
Species Common tern
Start year 1970
End year 2005 (continued by others, but not in this database)
Continuous collection of data No. Island was occupied by large gulls from 1974-1992; gulls were removed in 1992 and terns immediately recolonized.
Gap years 1973-1994
Longest data collection 12
Parental ID's recorded Yes, at some (but not all) numbered nests
List of basic breeding data collected Mate identity (in some but not all cases); laydates of each egg, clutch-size,  hatchdates of each egg, hatching success, chick growth and survival, productivity.
Description of the protocols for breeding data collection See Tims, J., I. C. T. Nisbet, M. S. Friar, C. Mostello and J. J. Hatch.  2004.  Characteristics and performance of Common Terns in old and newly-established colonies.  Waterbirds 27: 321–332.
Description of the protocols for taking individual level measurements NA
Experimental manipulations Yes
Description of experimental manipulations See Hatch, J. J. and I. C. T. Nisbet.  2011.  Costs of incubation in Common Terns: replication and extension of a clutch augmentation experiment.  Ibis 153: 185–189.
Predation events recorded Nest predation was rare at Ram Island during the observation period, but a few cases are recorded in the 'Notes' column.
How are second clutches recorded? Second clutches are very rare in common terns and replacement clutches were rare because common terns rarely failed during the study period.
Catching data
Individual data Yes
Type of individual data Parental body-mass, head-length, wing-length, chick growth.
Feeding data Yes
Type of feeding data See Tims, J., I. C. T. Nisbet, M. S. Friar, C. Mostello and J. J. Hatch.  2004.  Characteristics and performance of Common Terns in old and newly-established colonies.  Waterbirds 27: 321–332.
