12. Load lightening describes lower overall levels of investment in the presence of helpers. Mothers may increase clutch size in the presence of helpers (26) and to do so may reduce the size of each egg, but this is not load lightening because increases in clutch size will usually be associated with increases (not decreases) in maternal investment.

22. Experimental removal of helpers in superb fairy-wrens close to the onset of egg laying causes females to abandon their attempt (17), consistent with the prediction that females use helper presence as a cue for egg investment.
