README This data file is published by the Movebank Data Repository (www.datarepository.movebank.org). As of the time of publication, a version of the published animal tracking data set can be viewed on Movebank (www.movebank.org) in the study "Toucan movement and seed dispersal, Gamboa, Panama (data from Kays et al. 2011)". Individual attributes in the data files are defined below and in the Movebank Attribute Dictionary, available at www.movebank.org/node/2381. This data package is an update of doi:10.5441/001/1.62r58302. It was discovered after publication that the timestamps in this original version were corrupted. In this corrected version, the timestamps are correct. In addition, reference data and a readme file containing additional information about the data were added to reflect our current archiving practices. This current package also includes data for 3 collared aracari (Pteroglossus torquatus) that were collected as part of the same study but not included in analysis or paper due to small sample size. Methods for these deployments were the same as described in the paper. This data package includes the following data files: Toucan movement and seed dispersal, Gamboa, Panama (data from Kays et al. 2011)-acc.csv.zip Toucan movement and seed dispersal, Gamboa, Panama (data from Kays et al. 2011)-gps.csv Toucan movement and seed dispersal, Gamboa, Panama (data from Kays et al. 2011)-reference-data.csv These data are described in the following written publication: Kays R, Jansen PA, Knecht EMH, Vohwinkel R, Wikelski R (2011) The effect of feeding time on dispersal of Virola seeds by toucans determined from GPS tracking and accelerometers.

This identifier can be a ring number, a name, the same as the associated tag ID, etc. If the data owner does not provide an Animal ID, an internal Movebank animal identifier may sometimes be shown. example: 91876A, Gary same as: individual-local-identifier attachment type: The way a tag is attached to an animal. Values are chosen from a controlled list: collar: The tag is attached by a collar around the animal's neck. glue: The tag is attached to the animal using glue. harness: The tag is attached to the animal using a harness. implant: The tag is placed under the skin of the an animal. tape: The tag is attached to the animal using tape. other: user specified deploy off timestamp: The timestamp when the tag deployment ended. example: 2009-10-01 12:00:00.000 format: yyyy-MM-dd HH:mm:ss.sss units: UTC (Coordinated Universal Time) or GPS time, which is a few leap seconds different from UTC same as: deploy off date deploy on timestamp: The timestamp when the tag deployment started. example: 2008-08-30 18:00:00.000 format: yyyy-MM-dd HH:mm:ss.sss units: UTC (Coordinated Universal Time) or GPS time, which is a few leap seconds different from UTC same as: deploy on date deployment ID: A unique identifier for the deployment of a tag on animal, provided by the data owner. If the data owner does not provide a Deployment ID, an internal Movebank deployment identifier may sometimes be shown. example: Jane-Tag42 duty cycle: Remarks associated with the duty cycle of a tag during the deployment, describing the times it is on/off and the frequency at which it transmits or records data. example: it turns off during the night units: Any units should be defined in the remarks. e-obs acceleration axes: This tells you about the enabled ACC axes, like X and/or Y and/or Z (definition from "e-obs GPS-acceleration-tags application note: How to use the acceleration sensor, interpret, analyse its data and how to get values in m/s^2", 2011). example: XYZ units: none e-obs acceleration sampling frequency per axis: This is the sampling frequency for one axis. Don't mix this up with the sampling frequency for all axes together. For example if you have three ACC axes enabled, then the sampling frequency for all axes together is three times the sampling frequency for one axis. The sampling frequency is measured in Hertz, which is the same as 1/second. For example a sampling frequency of 10 Hz means that you get 10 samples per second (definition from "e-obs GPS-acceleration-tags application note: How to use the acceleration sensor, interpret, analyse its data and how to get values in m/s^2", 2011). example: 5.93 units: hertz (Hz) e-obs accelerations raw: Acceleration along the X and or Y and or Z axes of the tag, depending on which axes were activated on the tag as described in the field e-obs acceleration axes. Measurements alternate one measurement for each active axis in alphabetical order. The values are digital readings between 0 and 4095 of the analogue digital converter on the tag, and can be converted to m/s^2 with proper calibration. These samples are made at the rate described by the field e-obs acceleration sampling frequency per axis starting with the first sample at the time described in the field e-obs start timestamp. Tags with numbers e-obs numbers 2242 and higher, which began being provided in spring 2012, have Y-axis values in the opposite direction from those in older tags (definition from "e-obs GPS-acceleration-tags application note: How to use the acceleration sensor, interpret, analyse its data and how to get values in m/s^2", 2011; Wolgang Heidrich, e-obs Digital Telemetry, personal communication, 2012). example: 1844 1889 1653 1845 1896 1653 1837 1897 1653 1842 1898 1650 1844 1899 1644 1840… units: none (values must be calibrated and converted) e-obs battery voltage: Unloaded battery voltage (definition from Franz Kümmeth, e-obs Digital Telemetry, personal communication, 2012). example: 3712 units: millivolt (mV) e-obs fix battery voltage: Loaded battery voltage, i.e. battery voltage when GPS module is acquiring a fix (definition from e-obs Digital Telemetry Manual for DataDecoder Software, 2010; Franz Kümmeth, e-obs Digital Telemetry, personal communication, 2012). example: 3535 units: millivolt (mV) e-obs horizontal accuracy estimate: A horizontal (in)accuracy estimate, calculated by the GPS module (definition from e-obs Digital Telemetry Manual for DataDecoder Software, 2010; Franz Kümmeth, e-obs Digital Telemetry, personal communication, 2012). example: 35.07 units: meters e-obs key bin checksum: A checksum of the original binary data, so that Movebank can quickly compare different lines by comparing their checksums (definition from "e-obs GPS-acceleration-tags application note: How to use the acceleration sensor, interpret, analyse its data and how to get values in m/s^2", 2011). example: 4152324118 units: none e-obs speed accuracy estimate: A speed (in)accuracy estimate, calculated by the GPS module. The speed accuracy estimate (better named "inaccuracy estimation") may show very high values, since the GPS module calculates a very conservative value. These speed measurements are potentially very inaccurate when interpreting the data (definition from e-obs Digital Telemetry Manual for DataDecoder Software, 2010; Franz Kümmeth, e-obs Digital Telemetry, personal communication, 2012). example: 6.58 units: meters per second e-obs start timestamp: The date and time of day when the acceleration burst belonging to this line begins. The exact time of the first sample is a little later (up to 1 second) for older e-obs tags, especially when the ACC-pinger is enabled (4 pings before the start of eah ACC burst) (definition from "e-obs GPS-acceleration-tags application note: How to use the acceleration sensor, interpret, analyse its data and how to get values in m/s^2", 2011). example: 2011-01-03 13:45:00.000 units: GPS time (GPST), which is a few leap seconds different from UTC (Coordinated Universal Time) e-obs status: The record status, from e-obs GPS/accelerometer tags (definition from e-obs Digital Telemetry Manual for DataDecoder Software, 2010). Allowed values are A = position and time within accuracy masks B = only time of week and weeknumber valid C = only weeknumber valid D = no valid data example: D units: none e-obs temperature: Temperature; this value is not calibrated and therefore very inaccurate (definition from e-obs Digital Telemetry Manual for DataDecoder Software, 2010). example: 45 units: degrees Celsius e-obs type of fix: The type of fix of data from e-obs GPS/accelerometer tags (definition from e-obs Digital Telemetry Manual for DataDecoder Software, 2010). Allowed values are 3 = 3D fix 2 = 2D fix example: 3 units: none e-obs used time to get fix: The amount of time that was needed for this GPS fix; interesting for estimating power requirements (definition from e-obs Digital Telemetry Manual for DataDecoder Software, 2010). example: 22 units: seconds event ID: An identifier for the set of information associated with each record or event in a data set. A unique event ID is assigned to every time-location or other time-measurement record in Movebank. example: 6340565 units: none ground speed: The estimated ground speed between consecutive locations. example: 7.22 units: meters per second heading: The direction in which the tag moved from this location to the subsequent location, calculated as the bearing between consecutive locations, in decimal degrees clockwise from north; for example, 0 = north, 90 = east, 180 = south. example: 315.88 units: decimal degrees height above ellipsoid: The height above the ellipsoid returned by the GPS unit. (If altitudes are calculated as height above mean sea level, use height above mean sea level.) example: 24.8 units: meters latitude (decimal degree): The geographic longitude of a location along an animal track as estimated by the processed sensor data. Positive values are east of the Greenwich Meridian, negative values are west of it. example: -121.1761111 units: decimal degrees, WGS84 reference system same as: location lat life stage: The age class or life stage of the animal at the beginning of the deployment. Can be years or months of age or terms such as "adult", "subadult" and "juvenile". Units should be defined in the values (e.g. "2 years"). example: juvenile, adult units: Any units should be defined in the remarks. longitude (decimal degree): The geographic longitude of a location along an animal track as estimated by the processed sensor data. Positive values are east of the Greenwich Meridian, negative values are west of it. example: -121.1761111 units: decimal degrees, WGS84 reference system same as: location long manipulation type: The way in which the animal was manipulated during the deployment. Additional details about the manipulation can be provided using manipulation comments. Values are chosen from a controlled list: confined: The animal's movement was restricted to within a defined area. none: The animal received no treatment other than the tag attachment. relocated: The animal was released from a site other than the one at which it was captured. manipulated other: The animal was manipulated in some other way, such as a physiological manipulation. sensor type: The type of sensor with which data were collected.
