Distribution-wide morphometric data of Jungle Crows (Corvus macrorhynchos)

Here we present a dataset derived from standardised photography of museum specimens of Jungle Crows (Corvus macrorhynchos), a widespread Asian Corvid. We photographed 1105 crows, of which 1069 we managed to collect measurements of hard tissue (i.e., bill characteristics and tarsus length). We combined these measurements with museum curated data on the locality of the specimens, resulting in a geo-tagged dataset of crow morphology. The measured crows originated from across their distribution, representing the most comprehensive morphometric dataset for Corvus macrorhynchos to date.

The data consists of three .csv files:

• Museum Crow Measurements Metadata.csv contains the information on the columns contained in Museum Crow Measurements.csv split into Column and Details, where column names match those found in Museum Crow Measurements.csv, and details provide information on the data within that column.
• Museum Crow Measurements.csv represents the core data table containing all hard tissue measurements of C. macrorhynchos alongside museum derived field and manually review location fields. Each row equals an individual specimen and missing data are denoted with <NA>.
• Museum Crow Measurements Epicollect.csv contains the information collected alongside the images taken via Epicollect. The data was used to link photos and subsequent measurements to museum metadata.
