Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
This workbook contains data related to the museum egg color analyses and only includes data from the eggs at the CSIRO museum in Canbera, ACT, Australia or eggs from the field in Sydney, NSW and Canberra, ACT that were blown prior to measuring. The first sheet contains the average spectrophotometric data at each wavelength for each clutch and koel egg, which was used to determine the color catch cone values (second sheet). The second sheet contains the color catch cone values for all four avian color cones (VS, SWS, MWS, LWS) and the double cone for luminance. These color catch cone values were used in the discriminate function analysis to determine if koels exhibit host-specific races in color and the color catchcone values were also used to calculate Just Notcieable Differences (JNDs) to compare egg colors and luminances between species. For more information about each clutch, please see the supplemental material in the manuscript. For more information about the analyses, please see the Methods and Results section in the manuscript.
