Does anyone know what the eBird codes ‘C1’ ‘C2’ ‘C3’ or ‘C4’ mean, under ‘reproductive condition’?
They are not listed as standard codes on the eBird websites that I can see.
Is the number appended to the ‘C’ some sort of qualifier for observations of courtship or copulation?
They have turned up in a database of royal spoonbill records downloaded from the Atlas of Living Australia, in all states and territories, from multiple observers.
Thanks in advance,
