MMH applies virtually exclusively to specialist feeders. Other taxa, e.g. lizards, are more of a generalist type of feeder that is not dependent on any one type of food resource. Instances where either a match or mismatch is proposed always rely on the predator that is highly dependent on a singular type of resource (Visser et al. 1998, Visser &amp; Holleman 2001, Cushing 1990). However, even more generalist species suffer from mismatch if their main food source is highly seasonal. The European pied flycatcher for example compensates a lack of caterpillars with flying insects, but this negatively affects offspring condition (Samplonius et al. 2016). Whilst, the generalist diet of the wood warbler "Phylloscopus sibilatrix" is also thought to be why no effect was observed in a mis-match between peak caterpillar biomass and breeding success. Also, the predators and the prey must be relying on different abiotic cues (Durant et al. 2007). Typical instances also have the predator relying on an annually fixed abiotic cue, and the prey tends to use a cue that varies year to year (see above citations).
