Relationship between young/adult ratio and summer red-legged partridge abundance.
Relationship between young/adult ratio and summer red-legged partridge abundance (total partridges observed within 300 m /number of count points). In white, data from the four estates eliminated from analyses (see methods). Also presented is the regression line and r2 of the relationship for considered estates.
