At this time of year, people are thrilled to see the first signs of early spring – jonquils and the first silver wattles in flower. But for me – it’s the sound of chip chip, chip chip – the arrival of the Striated Pardalotes that give me that spring thrill.

Pardalotes are tiny birds with big heads and little tails – described as cigar-shaped in the bird books! We have two kinds locally – the Spotted Pardalote and the Striated Pardalote. Spotted Pardalotes are covered in lots of delightful white spots, whereas the Striated Pardalotes lack spots and have a greyish back and a distinctive yellow black stripe above the eye.  Both species are 10 centimetres or under in length!

Spotteds tend to be heard in our forests and woodlands all year round with their sweet sleep- de-de call which is musical and surprisingly loud. The Striateds are a complex species with a number of subspecies in different parts of the country – including a Tasmanian form that migrates to south-eastern Australia in Autumn and Winter.

So where are “my” Striated’s from? Are they always here, high up in the canopy but silent until late August when breeding begins? Or are they calling as they gather together in flocks before heading back to Tassie?

In Porcupine Ridge I usually hear one or two birds on my usual walk. But the other day whilst birdwatching on Bald Hill near Kyneton I had the great pleasure of being surrounded by a flock of at least a hundred pardalotes!

There were a few Spotted Pardalotes calling, but also the calls of the Striateds, and most of the birds I could see in my binoculars were Striated Pardalotes. As the tiny birds bustled busily over the leaves of the huge old narrow-leaved peppermints, these pop pop pop sounds filled the air.

The popping was the sound of the pardalotes crunching up and eating Psyllids and lerps. Lerps are the sugary coatings of the psyllid bug, which feeds on eucalyptus leaves. Pardalotes perform an essential ecosystem service by making sure trees do not get high numbers of these sap sucking bugs!

According to my Australian Bird Guide – the Tassie subspecies breeds on the island in summer and spends autumn winter on the mainland, and the other subspecies of Striated Pardalotes breeds in Victoria in Summer but then moves north up the coast in autumn-winter. Both kinds may gather in large flocks during migration or the non-breeding period. Were these birds coming from or on their way to Tasmania? Or perhaps local Victorian birds flocking together just before breeding season commences? It is amazing how much we have to learn about even our common birds!

Editor’s note:An earlier version of this story incorrectly indicated “Spotted Pardalotes” in the headline. Spotted Pardalotes can be found locally year round. It is the appearance of Striated Pardalotes that signal spring. The editor apologises for the error.
