Morphological measurements taken during handling of birds under study. One row per animal sighting.
| Field name | Field type | Field length | Field description |
|---|---|---|---|
| bird_morph_id | integer | None | Unique record id number | sighting_id | integer | None | Refers to the associated animal sighting in the Sightings table. | culmen | double precision | None | Measured with calipers, the length of the bird's bill from the junction between the feathers and bill above the nares, to the bill tip. Measured in mm. | tarsus | double precision | None | Measured with calipers, it is the length of the bird's tarsal bone. Measured in mm. | max_bill_height | double precision | None | Measured with calipers, it is the maximum height of the bill, measured at the anterior end. Measured in mm. | min_bill_height | double precision | None | Measured with calipers, it is the minimum height of the bill measured posterior of the maximum bill height. Measured in mm. Pertains mostly to albatrosses. | shoulders | double precision | None | Measured with a tape measure, it is the distance between the bird's shoulder blades, with the tape held against the feathers. Measured in cm. | max_girth | double precision | None | Measured with a tape measure, it the maximum girth or distance around the widest part of the bird. Measured in cm. | wing_span | double precision | None | Measured with a tape measure, it is the maximum length of an outstretched wing, measured from the spine to the end of the outer primaries of a single wing. Measured in cm, then doubled for total wing span. | wing_length | double precision | None | Measured with a flat ruler, it is the length of the wing from the 'wrist' to the tip of the outer primaries with the wing press flat on top of the ruler. Measured in cm. | comments | text | None | Comments about these measurements. | flat_wing_length | double precision | None | Measurement from wrist to tip of primaries. |
