The script reads in data; and creates a base 1-degree ASCII grid ('MAPSgrid.txt'), a model file for WinBUGS ('spatialcjs.txt'), and objects needed to run the model in WinBUGS. The script calls WinBUGS and stores output in an R list called 'out'. The script also creates objects for creating spatial maps of survival and residency (as in Fig. 3) within R and writes ASCII grids for making maps with GIS software outside of R. </p> <p>The data in 'woth.txt' are capture histories derived from the Monitoring Avian Productivity and Survivorship (MAPS) program. Included are all records of adult birds (i.e., ‘after-hatch-year’) of both sexes at stations where the species is known to breed. Fields in ‘woth.txt’ include:</p> <ol> <li>SPEC – Species 4-letter code. WOTH = wood thrush (<i>Hylocichla mustelina</i>)</li> <li>STA2 – MAPS station 4-character code. Stations consist of about 10 mist nets that sample an area of approximately 20 ha. Multiple stations < 1 km apart were considered a single station</li> <li>BAND – USGS Bird Banding Laboratory band number</li> <li>R – Indicates whether predetermined resident (M) or not (U)</li> <li>Y1 – Indicator variable denoting whether captured (1) or not captured (0) in year 1. Y1 corresponds to 1992, the first year of the study (first year of standardized MAPS protocol)</li> <li>Y2 – Indicator variable denoting whether captured (1) or not captured (0) in year 2 (1993)</li> <li>Y3 – Indicator variable denoting whether captured (1) or not captured (0) in year 3 (1994)</li> <li>Y4 – Indicator variable denoting whether captured (1) or not captured (0) in year 4 (1995)</li> <li>Y5 – Indicator variable denoting whether captured (1) or not captured (0) in year 5 (1996)</li> <li>Y6 – Indicator variable denoting whether captured (1) or not captured (0) in year 6 (1997)</li> <li>Y7 – Indicator variable denoting whether captured (1) or not captured (0) in year 7 (1998)</li> <li>Y8 – Indicator variable denoting whether captured (1) or not captured (0) in year 8 (1999)</li> <li>Y9 – Indicator variable denoting whether captured (1) or not captured (0) in year 9 (2000)</li> <li>Y10 – Indicator variable denoting whether captured (1) or not captured (0) in year 10 (2001)</li> <li>Y11 – Indicator variable denoting whether captured (1) or not captured (0) in year 11 (2002)</li> <li>Y12 – Indicator variable denoting whether captured (1) or not captured (0) in year 12 (2003)</li> <li>LAT – Latitude of the MAPS station in decimal degrees</li> <li>LONG – Longitude of the MAPS station in decimal degrees</li> <li>CAP – Mean no. of within-year captures per individual at the station</li> </ol> <p>Note that although 6,645 birds are included in the woth.txt, only 6,241 of these birds that were captured for the first time prior to the last year of the study are read into the data object used in the model.</p> </blockquote

    <p>Predicted productivity (probability of capturing a hatching-year bird; <i>p</i>[<i>Y</i>]<sub><i>st</i></sub> ± 95% confidence intervals) in relation to deviation of the enhanced vegetation index (EVI) from 5-year mean values during the late dry season (Mar-May; <i>evi</i>.<i>d</i>.<i>dev</i><sub><i>st</i></sub>) at three levels of late wet season EVI deviation values (from previous Sep-Nov; <i>evi</i>.<i>w</i>.<i>dev</i><sub><i>st-1</i></sub>). Predictions are based on top-performing (lowest AIC<sub><i>c</i></sub>) models for the three target species using capture data collected during the 10 periods (11 April-19 July) sampled in each of the five years (2008–2012).</p

    <p>EVI values represent interpolated monthly EVI values over the four 1-km<sup>2</sup> pixels closest to station coordinates. EVI values are plotted (A) by month (individual points represent year-specific values for each station; boxplots delineate quartiles with whiskers bounding the 95<sup>th</sup> percentile) and (B-C) by year during the late dry (B: Mar-May) and wet (C: Sep-Nov) seasons.</p
