Many other animals such as lorikeets, honey-eaters, flying foxes and nectar-eating bats are fully dependent on pollen as a protein source. Each of these animals will have their own essential amino-acid requirements and each species will need to obtain their requirements from the pollen.

A small sample of eight floral sources and all the amino-acids tested indicated that proline and glutamic acid are major amino-acids of eucalypt pollen.

The following tables sets out the maximum, minimum and mean for all amino- acids tested in these eight pollen floral sources.
