Migratory behaviour

This measurement type should be used to record either the fact that a species exhibits migratory behaviour or, if available, the extent of migrations. If a source only indicates that migratory behaviour has been observed then the user should choose ‘NA’ from Units and type ‘Yes’ in the Data Value field. If a source gives the extent of migratory behaviour then choose the approprriate units and enter the distance or areas in Data Value.

Generic value types: Data Value, Data Range, Measure, Sample Size, Captivity Status, Sex and Source Type.
