Characteristic Odour

The metasternal gland secretion of Phoracantha synonyma contains a diversity of volatile components, one of which, 2-hydroxy-6-methylbenzaldehyde (1), is of widespread occurrence in the genus. Threemajor components and several minor components are macrocyclic lactones, of which the following have been positively identified: decan-9-olide (2), (2)-dec-4-en-9-olide (3) and 11-hydroxytetradec-5-en-13-olide (4). The methyl and ethyl esters of 2-methylbutyric and related acids are also present and are responsible for the characteristic odour of the fresh secretion.

Metasternal Gland

The metasternal gland secretion of Phoracantha semipunctata contains five significant volatile components, of which the most abundant is 2-hydroxy-6-methyl-benzaldehyde (1). The second most abundant component, which has been named phoraoanthol, has been shown by synthesis to be (5-ethylcyclopent-1-enyl)methanol (2). The three other components are aldehydes, derivable from phoracanthol and cis- and trans-dihydrophoracanthols, respectively. Apparently all five components are related biosynthetically.

Branched Alcohols

The uropygial gland fats from four species of the family Corvidae are found to be mainly mono­ ester waxes, which consist of mono-, di-, and trimethyl substituted fatty acids and n- and methyl-branched alcohols. The positions of all methyl brandlings are even-numbered, the 2-position is preferred. About 2 - 40% of the secretions consist of triester waxes: Alkyl-hydroxy-malonic acids esterified with n-fatty acids and n-alcohols. Waxes of this type are very common in the uropygial gland fats of birds and therefore, in opposite to the monoester waxes, they are not usable for a chemotaxo­ nomy of birds.
