Data from: The Amazon Basin's rivers and lakes support Nearctic-breeding shorebirds during southward migration

Shorebird movement data used in habitat analyses for "The Amazon Basin's rivers and lakes support Nearctic-breeding shorebirds during southward migration." Data were collected between 2016-2022 using Argos Platform Terminal Transmitters or Pinpoint GPS Argos transmitters affixed to six shorebird species: American Golden-Plovers (Pluvialis dominica), Hudsonian Godwits (Limosa haemastica), Lesser Yellowlegs (Tringa flavipes), and Buff-breasted (Calidris subruficollis), Pectoral (C. melanotos), and Upland Sandpipers (Bartramia longicauda). The devices were deployed by various research groups at sites outside the Amazon Basin. Data has been subset to the Amazon Basin and the approximate timeframe of southward migration (July-December) and filtered to relevant individuals. 

The CSV file contains the following variables:

'individual local identifier': a unique alphanumeric identifier for the individual

'timestamp': date-time of the location, in YYYY-mm-dd HH:mm:ss format

'location.long': longitude

'location.lat': latitude

'species': shorebird species alpha code

'lc': location quality class for Argos PTT (3, 2, 1, 0, A, B, Z) or GPS (G) locations

'argos.semi.major': the length of the semi-major axis of the error ellipse for Argos locations, in meters

'argos.semi.minor': the length of the semi-minor axis of the error ellipse for Argos locations, in meters

'argos.error.radius': one standard deviation (sigma) of the isotropic location error for Argos locations

'argos.orientation': the orientation of the semi-major axis of the error ellipse for Argos locations, in degrees clockwise from north

'gps.fix.type.raw': the type of GPS fix (2D, 3D)
