Description of the data and file structure

Birds were captured in order to sample blood for DNA barcoding. Standard morphological measurements were taken. 

Files and variables

File: MorphologyData.csv

Description: Each row represents a capture event. Individuals captured repeatedly have data in the NHMO and QAVES columns only once, because we did not take repeated genetic samples. Values of "none" in the QAVES column are for repeated captures without blood samples. Values of "none" in the NHMO column also include some individuals where blood samples were taken but not accessioned to the NHMO. In the other variables, "not taken" indicates individuals where measurements were not taken (e.g., due to the weight being outside the range of the scale). 

Variables

• Genus: Genus name
• species: specific epithet
• Ring number: leg ring number applied (from the Stavanger Museum in Norway)
• QAVES: Process ID from BOLD dataset QAVES (for all samples successfully DNA-barcoded; the sample with failed amplification lacks this label)
• NHMO: Accession number at the Natural History Museum of Oslo (NHMO). Only captures associated with physical specimens accessioned to the NHMO are labelled here. 
• Date captured: date captured
• Tarsus length (mm): taken with dial calipers accurate to 0.1 mm, from the notch of the intertarsal joint to the distal end of the tarsus, with toes bent down at a 90 degree angle
• Wing chord (mm) (not flattened): taken with a standard wing ruler to the nearest mm
• tail length (mm): taken to the nearest mm by inserting a clear ruler between the central rectrices until it touched the bird’s body. The length of the longest tail feather was noted.
• Bill length (mm): taken with dial calipers to the nearest 0.1 mm, from the bill tip to the distal point of the nares
• Bill width (mm): taken with dial calipers to the nearest 0.1 mm, at the distal point of the nares
• Bill depth (mm): taken with dial calipers to the nearest 0.1 mm, at the distal point of the nares
• Mass (g): taken with a spring scale, with accuracy depending on the scale’s weight range
• Fat (scale 0 - 5): roughly following the description in DOI: 10.2307/1368248
• Molt: comments on the status of molting
• Latitude (North): latitude of the center of the field location of capture
• Longitude (East): Longitude of the center of the field location of capture
