Yellow Robins

(from the Connecting Country website)

Eastern yellow robins. A common woodland species. Not endangered. No fancy breeding displays. Easy to spot. So why is Monash University putting so much effort into following every move of these birds?

Well, it turns out they are more remarkable than once thought.

Recently we discovered two unexpected genetic lineages in our familiar robins. These lineages lie neatly to the east and west of the Great Dividing Range. While they are genetically distinct, even with the best pair of Swarovski binoculars the two lineages look exactly the same to the human eye.

Here’s where it gets really interesting. Along the east and west boundary there are sites where the two genetic lineages coexist (e.g., Muckleford State Forest, Crusoe Reservoir, Bendigo). So, they are hanging out together but maintaining ‘genetic purity’. This means that while we can’t see the difference, the birds can.

We are witnessing the Eastern yellow robins split into two species!

This raises some interesting questions. How do the robins know that a potential mate is the same genetic lineage? What happens when they mate with a different lineage? Would they prefer to mate with a different lineage, or not at all? How successful are the hybrid offspring?

Later in May (date being finalised), Lana will be giving  a presentation  as she unpacks what is known (and not known) about the Eastern yellow robin. Volunteers are most welcome to join the field team from the 5-10 May on their colour banding project. Email lana.austin@monash.edu for more information.

Birds and more birds


Over the last few weeks, Muckleford Forest friends have been out doing bird surveys, based on our newly established 2ha 20minute survey areas.

Geoff Nevill has been coordinating this mighty effort, and the rest of us have been exploring and learning by trying – the best way to learn really.

Read about the collective efforts of birders across our area here, and the great leadership offered by people like Tanya Loos and Geoff. This link explains more of what they have all been up to https://connectingcountry.org.au/birds-get-a-boost-in-the-goldfields-region/

 

Birds in the Muckleford Forest

We’ve just started ten bird survey transects in the Muckleford Forest!

There is a new page on our website with all the details. Let us know if you want to join in! We’ll report on results via the website and posts.

Good ‘swiftie’ news from Tassie too – Birdlife Australia is reporting that the Tasmanian Upper House has voted down the proposal to allow logging in 356,000 hectares of forests including 12,000 ha of Critically Endangered Swift Parrot habitat.
