eBird users have the option of specifying breeding bird atlas codes for their observations, for example, if nesting building behaviour is observed. Use this filter to select only those observations with an associated breeding code. This function only defines the filter and, once all filters have been defined, auk_filter() should be used to call AWK and perform the filtering.

auk_breeding(x)

Arguments

x

auk_ebd object; reference to basic dataset file created by auk_ebd().

Value

An auk_ebd object.
