Abstract
Methods
Data collection details are described in the associated publication (Sofaer et al. Journal of Avian Biology). Data are based on video recordings of orange-crowned warbler (Leiothlypis celata) incubation behavior, and observations of incubation period length. The data on nest attentiveness are summarized from the on and off bout data.
Usage notes
Definitions of data columns:
OCWA_OnOffBouts.csv: This file contains on and off bout data transcribed from video recordings, and associated hourly temperature from nearby weather stations.
- Pop: AK or CA, corresponding to Alaska or California
- NestID: nest identity
- OnDate: date of start of on-bout; format is m/d/yyyy
- OffDate: date of end of on-bout; format is m/d/yyyy
- IncStartTime: time at start of on-bout; format is hh:mm:ss
- IncEndTime: time at end of on-bout; format is hh:mm:ss
- ExcludeON: binary; has value of 1 if on-bout duration should be excluded from analyses (e.g., because incomplete)
- ExcludeOFF: binary; has value of 1 if off-bout duration should be excluded from analyses (e.g., because incomplete)
- NOTES: description of any uncertinaty in video observation or other notes
- Overnight: binary; 1 if the on and off times correspond to an overnight period
- OnMin: duration of on-bout (min.)
- OffMin: duration of off-bout (min.)
- StartHour: integer hour of on-bout start time
- TempC_mean: mean temperature (degrees C) during the hour starting at StartHour
- TempC_max: maximum temperature (degrees C) during the hour starting at StartHour
- TempC_min: minimum temperature (degrees C) during the hour starting at StartHour
- Precip_mm: total precipitation (mm) recorded during the hour starting at StartHour
OCWA_DaytimeAtten.csv: This file contains hourly nest attentiveness during active hours (i.e., excluding the overnight period) and associated weather.
- Pop: AK or CA, corresponding to Alaska or California
- NestID: nest identity
- Date: date of observation; format is m/d/yyyy
- StartHour: integer hour over which atteniveness is summarized
- Atten.min: number of minites on the nest during that hour (maximum of 60)
- TempC_mean: mean temperature (degrees C) during the hour starting at StartHour
- TempC_max: maximum temperature (degrees C) during the hour starting at StartHour
- TempC_min: minimum temperature (degrees C) during the hour starting at StartHour
- Precip_mm: total precipitation (mm) recorded during the hour starting at StartHour
OCWA_IncPeriod.csv: Incubation period duration data
- Pop: AK or CA, corresponding to Alaska or California
- NestID: nest identity
- NumEggs: number of eggs observed in nest
- NumHatched: number of young hatched
- clutch_yearday: day of year of clutch completion date
- hatch_yearday: day of year of first egg hatching
- IncLength: duration of incubation period (number of days)
