In the strictest sense, nuclear species are probably not needed for flock formation.
Besides being conspicuous, a nuclear species is often among the commonest ones (Hutto, 1994).
Other potential nuclear species, Icterus cayanensis and Molothrus badius, besides being intraspecifically gregarious, occurred for prolonged periods within mixed flocks.
Therefore, as found for most other studies, the organization of Neotropical bird mixed flocks is unrelated to foraging advantages, as well as the role of nuclear species being unrelated to feeding benefits (Hutto, 1994).
