Twenty-eight × Port Lincoln Parrot

“The south-western forest form, semitorquatus, with its all-green
belly and prominent red frons, intergrades sharply with the smaller,
inland and arid-country form zonarius, with its broad yellow-
breast-band and vestigial red frons, on the eastern margins of the
sclerophyll forest of jarrah-marr-kam (Fisher 1970; Serverty &
Whittell 1976; Forshaw 1981). Following widespread land clear-
ing, zonarius genes have now introgressed semitorquatus on the
Swan coastal plain (Fisher 1970).”

The Western Splendid Fairywren (Malurus splendens splendens) is a subspecies of the Splendid Fairywren found across the semi-arid inland midwest and the forested southwest of Western Australia.(*1)

There are 4 subspecies recognized (*2) with much geographic variation in males' breeding plumage. (*3)

M.s.splendens is the darkest, with bright violet hue to dorsum, bib and belly(*1)

Introduction:
Eucalypts are almost a defining feature of Australia. They are the dominant tree of the higher rainfall areas of the country, and sparsely represented in the driest regions. There are nearly 900 species which have adapted to nearly every environment. In EUCLID we include the long-standing genus Angophora, which is exclusive to eastern Australia excluding Tasmania, and the recently recognised Corymbia, occurring primarily in northern Australia.

Identifying eucalypts:
Identification has always been regarded as difficult, partly due to the lack of instruction on specific botanical characteristics. Understanding the eucalypt plant is a vital element in attempting the identification process.
Eucalypt leaf morphology provides a range of diagnostic features as well as injects a level of confusion in the change from seedling to juvenile to sapling to adult leaves that takes place in the majority of species.

In eucalypts there is a striking array of juvenile or seedling leaf types from opposite and completely connate pairs of leaves, to crowded and spirally arranged short linear leaves, to disjunct petiolate ovate leaves (many species, e.g. E. obliqua, E. ewartiana, C. terminalis), even leaves with peltate leaf bases (e.g. C. citriodora).

To aid identification the observer in the field also needs to take into account other aspects of the specimen, viz. the height of the plant, the number of stems or trunks, the colour of the crown, the overall appearance of the crown to determine if it is composed of juvenile or adult leaves, general size of the leaves (very small, e.g. E. parvula or E. kruseana, or very large, e.g. E. globulus) and the type of bark, basically, whether rough or smooth, and extent of coverage by the rough bark of the smaller branchlets. The observer also needs bear in mind there is often considerable variation in some characters between trees of the same species in one population, especially in size of parts, such as length and width of leaves, length of petioles, bud sizes, lengths of peduncles and pedicels, and fruit dimensions and position of the disc relative to the rim of the fruit.
