Given that interest is now stirring over how the ‘official’ Australian list will be maintained in the future, it’s worth a look back over the long-simmering arguments around the species status of the Western Fieldwren.
|Western Fieldwren Calamanthus [campestris] montanellus from the Stirling Ranges. Note the olive toned and heavily-streaked back; creamy-buffy underparts; russet on head confined to forehead; limited rufous in rump and tailbase; brown (not chestnut) lores; dull tail tips. This individual has a little more rufous than a ‘classic’ montanellus, notably in the cap and fringing on the wings. |
