The Australian magpie (Gymnorhina tibicen) is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is placed in its own genus Gymnorhina and is most closely related to the black butcherbird (Melloria quoyi). It is not, however, closely related to the European magpie, which is a corvid. The adult Australian magpie is a fairly robust bird ranging from 37 to in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings. The male has pure white feathers on the back of the head and the female has white blending to grey feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground. Described as one of Australia's most accomplished songbirds, the Australian magpie has an array of complex vocalisations. It is omnivorous, with the bulk of its varied diet made up of invertebrates. It is generally sedentary and territorial throughout its range. Common and widespread, it has adapted well to human habitation and is a familiar bird of parks, gardens and farmland in Australia and New Guinea. This species is commonly fed by households around the country, but in spring (and occasionally in autumn) a small minority of breeding magpies (almost always males) become aggressive, swooping and attacking those who approach their nests. Research has shown magpies can recognise at least 100 different people, and may be less likely to swoop individuals they have befriended. Over 1000 Australian magpies were introduced into New Zealand from 1864 to 1874,Haether, B.; Robertson, H. (2015). The Field Guide to the Birds of New Zealand. p. 413 but have subsequently been accused of displacing native birds and are now treated as a pest species. Introductions also occurred in the Solomon Islands and Fiji, where the birds are not considered an invasive species. The Australian magpie is the mascot of several Australian (and New Zealand) sporting teams, most notably the Collingwood Magpies, the Western Suburbs Magpies, Port Adelaide Magpies and, in New Zealand, the Hawke's Bay Magpies.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Gymnorhina tibicen has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
Besides the big genome in the nucleus, cells carry a small, circular loop of DNA inside the cell's energy factories — the mitochondria. It is inherited almost only from the mother and is a leftover from ancient bacteria that moved into the cell. The mitochondrial markers above (ND*, COX, CYTB…) are read from exactly this loop. Outer ring = one strand, inner ring = the other.
The complete instruction manual Gymnorhina tibicen carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The solid bar is the fossil range: the span between the oldest and the youngest fossil that palaeontologists have assigned to Gymnorhina tibicen. Above itBeside it, each dot is one dated fossil find — few enough to count, so they are drawn individually rather than as a graph. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil. Where the DNA reaches further back than the oldest fossil, the gap is hatched: the ghost lineage. It means the lineage was already out there, but has left us nothing we have dug up yet.

Where the DNA of Gymnorhina tibicen was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
