Supplemetary Information from Generational shift in spring staging site use by a long-distance migratory bird

Contains tables S1, S2, S3, S4 and figure S1

Yearly Black-tailed Godwit Return Rates

This data includes data on whether or not an individual godwit that was seen in one year, returned to their breeding grounds the following year. All data is categorized in reference to individual godwits (signified by their Colour Code). The initial year in which an individual was seen is not marked, only the following year is denoted with a 0 (not seen) or a 1 (seen). It also includes a column denoting each molecular individual's sex--0 (unknown), 1 (female), and 2 (male)

Breeding Propensity

This files contains data on the breeding propensity of Black-tailed Godwits seen in our study area prior to the initiation of the first nest from 2005-2014. A 0 denotes that an individual was not found nesting, a 1 that it was found nesting, and a blank that it was not seen in that year

All nests 2005-2014

This file contains data on nests found in our study area in Friesland between 2005-2014. It includes their hatching success, fledging success, clutch size, average egg volume, and initiation date, as well as the colour code of the corresponding adults. In all cases, 0 denotes a negative result (i.e., nest failed to hatch), and 1 a positive result (i.e., nest hatched)

2013 March-May Resightings of Black-tailed Godwits

This file includes the date and location of all resightings of individually colour-marked Black-tailed Godwits from March-May 2013 north of Iberia. The colour codes listed in this file match up with those used in all other files for this publication

Polder Counts

This file contains data on the number of territorial Black-tailed Godwits seen during our weekly survey of every parcel of every polder in our study area in Friesland during the pre-breeding period. In this file, NA = 0 territorial godwits during a survey period

Response Data

This file contains data pertaining to the behavioral response of all individual Black-tailed Godwits that were seen in our study in Friesland during the spring of 2013. It includes their reproductive parameters in both 2013 and 2014, as well as their individual arrival date history. Response type is coded as: 1 (stayed), 2 (reverse migrated), 3 (delayed arrival), and 4 (normally late arriving). For all other categories, 0 denotes a negative result (e.g., nest failed), while 1 denotes a positive result (e.g., fledged successfully)
