This replaces an earlier dataset that covered 1999-2001 (MON-EX-PRNWR-Salt-Marsh-Birds.01, knb-lter-pie.58.3) . PWRC considers this current dataset to be a more reliable estimation of bird numbers at the Parker River National Wildlife Refuge than the previous dataset. Version 02 created 22Feb2011.

(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Standard breeding bird censuses with 100 m radius counting circles. Observing periods divided into 0-3 min, 3-5 min, and 5-10 minutes for comparison with other censuses. For 3-5 min period, only additional birds not recorded in the 0-3 period are recorded. For 5-10 min period, only additional birds not recorded in the 0-5 min period are recorded. Birds recorded either visually or by sound. Counting circle boundaries set a minimum of 200 m from each other. Observer distinguished between birds within 50 m of the center point, birds from 50-100 m, and those beyond 100 m. Counts carried out from late May through August over a three-year period. Placement of circles within vegetated salt marsh habitat. NOTES AND COMMENTS: Temperature inconsistently recorded Variable description clarification- Beaufort scale: whole numbers from 1-12 with increasing wind based on observations of trees, waves, etc. (http://en.wikipedia.org/wiki/Beaufort_scale) AlphaCode- Four-letter codes, based on English names, broadly following the rules and strategies adopted by the U.S. Bird Banding Laboratory (BBL), http://www.birdpop.org/AlphaCodes.htm.

(508) 289 7485 pie_im@mbl.edu Information Manager The Plum Island Ecosystems (PIE) LTER is an integrated research, education and outreach program whose goal is to develop a predictive understanding of the long-term response of watershed and estuarine ecosystems at the land-sea interface to changes in climate, land use and sea level. The principal study site is the Plum Island Sound estuary, its coupled Parker, Rowley and Ipswich River watersheds and the adjacent coastal ocean, the Gulf of Maine. The PIE LTER focuses on how several aspects of global change influence organic matter and inorganic nutrient biogeochemistry and estuarine foodwebs. The inputs of organic matter and nutrients from land, ocean and marshes interact with the external drivers (climate, land use, river discharge, sea level) to dictate the extent and degree of nutrient and organic matter processing and determine the spatial patterns of estuarine productivity and trophic structure. This material is based upon work supported by the National Science Foundation under Grants OCE-9726921, OCE-0423565. Any opinions, findings, conclusions, or recommendations expressed in the material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. The Plum Island Ecosystems (PIE) LTER site, is located in northeastern Massachusetts, 42.72 N, 70.85 W. The PIE LTER lies at the interface of a thinly soiled, formerly glaciated New England land mass and the highly productive Gulf of Maine. Three watersheds comprise the estuarine drainage basin: Parker (155 km2), Rowley (26 km2) and Ipswich (404 km2). The Ipswich River watershed is highly urbanized with Boston "bedroom" communities encroaching in the headwater region while the Parker is less urbanized and retains a higher proportion of forest. -71.2198 -70.7568 42.8276 42.4965 0 100 meter uid=PIE,o=lter,dc=ecoinformatics,dc=org all public read MON-EX-PRNWR-Salt-Marsh-Birds.dat Census data on salt marsh birds using 100 m radius counting circles for the Parker River National Wildlife Refuge MON-EX-PRNWR-Salt-Marsh-Birds.dat 1 column , http://ecosystems.mbl.edu/PIE/data/MON/data/MON-EX-PRNWR-Salt-Marsh-Birds.dat PtName PtName Code name of individual counting circles Code name of individual counting circles SurveyDate SurveyDate The date of the survey dd-mmm-yyyy SurveyTime SurveyTime Time EST, 24 hour hh:mm Obs Obs Name of person making observations Name of person making observations TempC TempC Temperature at beginning of survey (oC).
