4-Fluoro-2-[(3-methylphenyl)iminomethyl]phenol

Abstract

The title compound, C14H12FNO, crystallizes as the trans phenol–imine tautomer. The two benzene rings are essentially coplanar, being inclined to one another by 9.28 (7)°. This is at least in part due to the intra­molecular O—H⋯N hydrogen bond between the hy­droxy O atom and the imine N atom. The crystal structure is stabilized by an array of weak C—H⋯O and C—H⋯F inter­actions, which link the mol­ecules into a stable three-dimensional network.

Social learning in nest-building birds: a role for familiarity

“…For our first-time builders, the identity of the watched bird was therefore important. This selective transfer of knowledge between some individuals, but not others, is a feature that promotes the formation and maintenance of cultural traditions [22][23][24][25]. For example, just as our birds learned which material to use based on its colour, so vervet monkeys (Chlorocebus aethiops) copy the colour choice of others feeding on pink or blue maize corn [23], and great tits (Parus major) copy the choice of door based on its colour (blue or red [25]).…”

In this study, we provide evidence that birds copy colour preferences for nest material expressed by familiar, but not unfamiliar, individuals even when this preference confers no mechanical advantage in terms of the final structure of that nest.…”
