Conservation Magazine's Journal Watch Online reports on the latest efforts to help the last few Kakapo Parrots breed, by comparing natural nutritional supplements such as nuts with other special formulas.

A group led by Glasgow University's David Houston describe how supplementary feeding can increase clutch sizes, but only if it’s the right supplement. A mixture of nuts – which the birds like – had no effect, whereas a specially formulated, more nutritionally-balanced pellet supplement led to significantly larger numbers of eggs.
