A puzzling parrot

Colour variations in Australian Ringnecks (ssp Mallee Ringneck)

We have a small flock of about 6 Mallee Ringnecks resident in our garden. We see them every day and they have breed successfully nearby. The Mallee Ringneck is a race of the Australian Ringneck and is found in areas which contain predominantly mallee tree habitat. Our 5 acre block is half covered in mallee trees, so they probably feel quite at home.

In recent weeks I’ve been aware that one of them has some interesting colour variations. In the photo above, the bird on the left has a much darker head than normal, plus more yellow on the chest and blue cheek feathers rather than green. Throughout the broad range of the Australian Ringneck there is considerable colour variation.

The Western Ringneck (also called the Port Lincoln Parrot) has a particularly dark head – it’s black in fact. Port Lincoln Parrots have been recorded in the Adelaide metropolitan region, but it is suspected that they were aviary escapes or releases. I’m not claiming that this bird is of the race, Port Lincoln Parrot, but I suspect it may have escaped from someone’s cage as they are a common aviary bird. Another possibility is that it is the progeny of cross breeding between a Mallee and a Port Lincoln Parrot, thus accounting for the washed out grey head rather than a black one. Both races interbreed readily in the Flinders Ranges where their ranges overlap.

The photo below shows a close up view of the same bird. The third photo shows the normal colours of the Mallee Ringneck.

I’d be very interested in reader’s comments.

Adelaide Rosella

The Adelaide Rosella is a race of the widespread Crimson Rosella. It is confined to the Adelaide region, the Mt Lofty Ranges and through to the mid north of South Australia. It is relatively common in that range and shows considerable colour variations, ranging from a washed out orange through to almost red.

I live in Murray Bridge which is about 80km SE of the Adelaide CBD and about 40km from the ranges. When we first moved here 30 years ago I had to travel 30 – 40km west to see this species. Over the years the range appears to have drifted further east and sightings in and around Murray Bridge are becoming far more common. I can’t claim this as a resident species in our garden, but sightings are becoming quite regular every few months so it might happen in the future.

On the weekend just gone we had two land in the Eremophila youngii bush in our front garden. This bush has been in flower for some time and the local honeyeaters love feeding on the nectar. The resident Mallee Ringnecks also feed on the flowers. These visiting rosellas came early in the morning and sat there briefly in full sunlight. I was just emerging from showering and shaving, and my camera was at the other end of the house. Naturally they flew off before I could take a photo.

One day.

One day they’ll pose nicely for me and I’ll be able to improve on the photo above. Meanwhile, I’ve included a close up photo of the flower (see below) as well as one showing a New Holland Honeyeater in the bush.

Opportunistic Magpies

Australian Magpie gathering wool for nesting material

It never ceases to amaze me when I consider how enterprising and opportunistic birds can be, especially when it comes to nesting time. It’s that time again and our resident Australian Magpies having been busy fighting to establish their territories. Our 5 acre block on the edge of town is the intersection of three territories, so at this time of the year there are many disputes over boundaries.

One pair dominates the area around our house and sheds and they are the birds that come most frequently to our bird baths and close to the house. They will often come right up to the front or back doors and allow us to get quite close. They are also quite happy to search for food only a metre or two from where we might be working or sitting in the garden. This includes our back veranda area where we often cook a BBQ and eat a meal.This is despite never having fed them in any way.

A few days ago my wife had a fleece of coloured wool out in the sunshine to dry. She was preparing it for spinning but our resident female magpie found it. Soon she was taking big chunks to the nest tree. Incensed at this free-loading, my wife brought the fleece onto the veranda and draped it over the clothes horse. Undeterred, the magpie enterprisingly found it and continued her nest lining activities. The photographic proof is shown on this post.

Southern Boobook Owl

Southern Boobook Owl, Murray Bridge

A few nights ago I was collecting our mail from the local post office at about 10:30pm (don’t ask why I was getting the mail so late at night – it’s another story). As I emerged from the car I was delighted to hear the distinctive call of a Boobook Owl nearby. The sound was probably coming from the trees near back of the Town Hall, or perhaps the nearby railway station. I didn’t have a torch with to track it down, nor did I have a camera with me, so I’ve used the photo of one I took in our garden a few months ago.

I guess I was a little surprised at first to hear an owl right there a few steps from the town’s CBD. When I thought about it the owl was probably resident in that area for a very good reason: food. Around the various shops and businesses and several schools within 500 metres, the pickings would have been good. Rats and mice abound in the area so it would probably not be going hungry. About ten years ago some students in the school in which I was teaching noticed one in the tree at the front of the school and pointed it out to me. Nice to know it’s surviving in this location.

Nankeen Kestrel, Laratinga wetlands, Mt Barker SA

Earlier this week I took a mid-morning break to have a coffee and to do some reading. It was a beautiful day with bright sunshine, moderate temperature and no clouds. It was the complete opposite of some of the dreary,gloomy, drizzly weather we’ve had this winter. I was enjoying the warmth of the sun, and the coffee wasn’t bad either.

As I read, a bird call nearby attracted my attention from my book. I’d heard this call several times in the previous few days but had not managed to catch sight of the birds. I recognised the call as that of a juvenile Nankeen Kestrel begging for food from the parents. A few seconds later an adult bird flew overhead, closely pursued by two young ones begging as they flew.

They went across our garden so quickly it was only a brief glimpse. They didn’t land nearby so there was no opportunity for a photo or two, so I’ve included a photo of a different bird of the same species taken in nearby Mt Barker some months ago. I have observed that they had been landing regularly on the cross bar of a nearby electricity power pole. Getting close enough without disturbing them can be a challenge as they can see me coming.

I’ll keep trying.

Good birding.
