Principal Investigator Contact Information Name: Fabio L. Tarazona-Tubens Institution: New Mexico State University Address: Email: fabio.tarazona08@gmail.com B. Associate or Co-investigator Contact Information Name: Martha J. Desmond Institution: New Mexico State University Address: Email: mdesmond@nmsu.edu 3. Date of data collection: Data was collected during the 2017-2018 YHPA breeding season. 4. Geographic location of data collection: All monitored nests were located in Belize, Central America. 5. Information about funding sources that supported the collection of the data: Field activities were made possible thanks funding provided by Loro Parque Fundación (contract PP-112-2018-1 awarded to Belize Bird Conservancy). Additional funding was provided by a grant through the USDA NIFA Hispanic Serving Institutions Program to M.J.D. (2015 38422-24068). SHARING/ACCESS INFORMATION 1. Recommended citation for this dataset: Tarazona-Tubens, Fabio et al. (2022), Data from: Temporal factors and distance to human settlement affect nest survival of the endangered Yellow-headed Parrot in Belize, Central America, Dryad, Dataset, https://doi.org/10.5061/dryad.9kd51c5kb DATA & FILE OVERVIEW 1. File List: Dataset is divided into three spreadsheets, named in relation to the fates of the nests contained in the spreadsheet. Each spreadsheet also contains nests that fledged successfully. Successfully fledged nests included in each spreadsheet are replicated (successful nests in predation spreadsheet are the same as those included in the abadonment spreadsheet). Each spreadsheet contains the encounter history for each nest, and other relevant information necesary to conduct daily nest survival analysis. Included are also the covariates included for each fate analysis, these are explained in detail below. 2. Relationship between files, if important: Each file can be analyzed independently. If a merged analysis between all fates is performed, successful nests need only be represented once. 3. Additional related data collected that was not included in the current data package: N/A 4. Are there multiple versions of the dataset? No, dataset as is can be utilized to conduct daily nest survival analysis. Any additional modifications on the covariates were conducted in R without modifying the original dataset. METHODOLOGICAL INFORMATION 1. Description of methods used for collection/generation of data: See Methods information on Tarazona-Tubens et al. (2022). Temporal factors and distance to human settlement affect nest survival of the endangered Yellow-headed Parrot in Belize, Central America. Ornithological Applications, duac010, https://doi.org/10.1093/ornithapp/duac010 2. Methods for processing the data: The dataset included here contains all the raw data. Any other necesary transformations on the variables were performed in R without transforming the dataset. 3. Instrument- or software-specific information needed to interpret the data: No specific software is needed to interpret the raw data. R and MARK programs were used to analyze the encounter history and obtain the nest survival probability. 4. Standards and calibration information, if appropriate: N/A 5. Environmental/experimental conditions: Dataset contains artificial and natural nests. Artificial nests were composed of wood boxes installed on trees. This study was observational and there were no manipulations done on the nests apart from the visual monitoring to determine if the nest was alive or not. DATA-SPECIFIC INFORMATION FOR: Yellow-headed Parrot (YHPA) Nest Survival Data Below is the information of the variables contained in each spreadsheet. The abbreviations included in the variable list match those included in the dataset, the description of each variable contains information on what the abbreviation stands for as well as a short description. Predation 1. Number of variables: 20 covariates 2. Number of cases/rows: 3. Variable List: Additional details on the variables and how they were collected can be found on the main text. FirstFound,LastPresent,LastChecked,Fate and Freq are standard variables required for nest survival analysis. Refer to MARK manual for their meaning and classification. Additional covariates include: Site- This variable was restricted on the dataset as not to provide any direct information on location of nests for this endangered species. SteOpenness- A measure of vegetation openness around the nest site at the landscape level. Year- Whether the nest was monitored in 2017/2018. AgeDay1- Nest age in days when the nest was first found. Height- Height of the nest cavity from the ground. Measured in meters. Depth- Distance from entrance of cavity to bottom. Measured in meters. Openness- Refers to canopy openness at the local scale. F.visibility- Frontal visibility from the nest entrance. Inclination- Inclination in degrees of the nest cavity. Entrance- Entrance width of the nest cavity. Measured in centimeters. ShrubCover- Percentage of shrubs on a plot around the nest tree. TreeDensity- Number of trees on a plot around the nest tree. Edge- Distance from the nest tree to the edge of nearest different habitat type. Abandonment 1. Number of variables: 18 2. Number of cases/rows: 3. Variable List: Additional details on the variables and how they were collected can be found on the main text. FirstFound,LastPresent,LastChecked,Fate and Freq are standard variables required for nest survival analysis. Refer to MARK manual for their meaning and classification. Additional covariates include: ShrubCover- Refers to the percentage of shrub cover around the nest tree. Site- This variable was restricted on the dataset as not to provide any direct information on location of nests for this endangered species. Condition- Refers to the condition of the nest tree- whether it was alive or dead. CortexDepth- Depth of the tree cortex at the nest entrance. CvtyDepth- Distance from entrance of cavity to bottom. Measured in meters. Aspect- Cardinal direction in which nest was facing. DBH- Diameter at breast height (cm) of the nest tree. Monitoring device- Whether the nest was monitored with a nest camera or an i-Button. CC- Canopy cover (%) around the nest. AgeDay1- Nest age in days when the nest was first found. * Covariates "Collapsed" and "Device" represent the same type of data presented in the Aspect and Monitoring device columns, respectively. Poaching 1. Number of variables: 16 2. Number of cases/rows: 3. Variable List: Additional details on the variables and how they were collected can be found on the main text. FirstFound,LastPresent,LastChecked,Fate and Freq are standard variables required for nest survival analysis. Refer to MARK manual for their meaning and classification. Additional covariates include: Height- Height of the nest cavity from the ground. Collected in meters. Depth- Distance from entrance of cavity to bottom. Collected in meters. Year- Whether the nest was monitored in 2017/2018. 0 = 2017 nests, 1= 2018 nests. PrevPchng- Whether the nest has been previously poached or not (yes/no). NestlingAge- Age of the nestlings when poached. For successful nests it has the age when fledged. AgeDay1- Nest age in days when the nest was first found. Road- Distance from the nest to the nearest road. Measured here in km. Settlement- Distance from nest to nearest human settlement. Measured here in km. Site- This variable was restricted on the dataset as not to provide any direct information on location of nests for this endangered species. SteOpenness- A measure of vegetation openness around the nest site at the landscape level. 4. Missing data codes: None contained.
