Bates·i·an mimicry

A form of protective mimicry, especially in insects, in which a species that is palatable or harmless closely resembles an unpalatable or harmful species and therefore is avoided by predators.

[After Henry Walter Bates (1825-1892), British naturalist.]

These nest observations are only the second published for the cinereous mourner, and they fit with the proposal that mourners exhibit Batesian mimicry.
However, we consider the patterns observed in the juveniles of these two species (and the nestling of Laniisoma) strongly suggest either a chemical defense (toxic and/or unpalatable) or Batesian mimicry (e.
This pattern is typical in cases of Batesian mimicry, in which the mimic is relatively scarce, palatable and unprotected while the model is abundant and wellprotected.
Chapter 3 traps Henry Walter Bates in the Amazon for 11 years of hardship where he collected 14,712 animal species (8,000 of whom were new to science) and 550 different species of butterflies, which led to the discovery of Batesian mimicry.
The selection pressure exerted by predators is strong and, as a consequence, traits associated with Batesian mimicry are expected to evolve rapidly (Mappes & Alatalo 1997).

The theory of Batesian mimicry holds that edible species that look like dangerous species will be protected, because predators evolve to avoid dangerous species--even without previous, real-life, bad dining experiences.
That means clicking works both as Mullerian mimicry (two unpalatable species benefiting by making similar sounds that predators can learn by catching either one) and Batesian mimicry (edible prey borrowing an "unpalatable" signal), says Barber.
