Corellas: Villains of the Bird World

Birding time out

From time to time I take out a few minutes from my day to go birding. Sometimes these few minutes stretch into a few hours. I recently took off a whole afternoon. During this time, I visited six birding spots around my home town of Murray Bridge which is about an hour’s drive south-east from Adelaide.

Sturt Reserve

One of the spots I visited was Sturt Reserve. This lovely spot is on the banks of the Murray River. It is named after Captain Charles Sturt who explored the river in 1830. The reserve has large areas of lawn for picnics, a large playground and a restaurant. It also plays host to a wide variety of birds.

Little Corellas

On my recent visit, there were quite a few Little Corellas in the trees along the river. In flocks of 30 – 50 they can be annoyingly noisy. In recent years, these flocks have grown into the hundreds on many occasions. They are known to be high on the list of the Villains of the Bird World.

Havoc

In large flocks like one can see at Sturt Reserve – and other spots around the district – they can wreak havoc on trees, stripping leaves, twigs and bark from trees until little is left but for a carpet of gum leaves on the ground below. The nearby lawn-tennis courts have also been a target of these destructive birds. They have sometimes left the courts unusable after the sharp beaks of several hundred birds have visited. Various methods to disperse the flocks have been tried, but without much success. This is a widespread problem in many places in South Australia.

Large flock

Later, I drove a few kilometres to the southern edge of town to visit Swanport Reserve, also on the banks of the river. Here I witnessed flocks of several hundred corellas flying along the river and then out onto recently cultivated farmland across the river. Because of the distance, I was only able to estimate their numbers. After many smaller flocks had joined into one large flock, there must have been at least 1200 birds – possibly as many as 2000.

The photos below were taken at Sturt Reserve. They show the playfulness of some of the birds on the street lights. While I couldn’t see any damage to the lights from their beaks, they are quite capable of causing the local council some expensive headaches.

What are these Galahs up to?

Galah, Mudgee, NSW

Galah, Mudgee, NSW

On our return trip from Sydney last year, we didn’t take the direct route home to Murray Bridge. Instead of taking two days to get home, we took a circuitous route through north-western New South Wales. We drove through Lithgow, Capertee Valley, Mudgee, Dunedoo, Cobar and Broken Hill. We saw some parts of the country we had never visited before, which is always an interesting way to travel.

On our first night away from Sydney, we stopped at one of the caravan parks in the town of Mudgee. We arrived late in the afternoon. After we had unpacked and settled into the cabin, we sat on the front deck of the cabin enjoying the balmy evening and a nice cuppa. As we were sitting there I had my notebook and binoculars at the ready, as well as my camera. My attention was soon drawn to a Galah perched in a nearby tree. This tree was about 30 metres from where we sat.

I noticed that the Galah was not attempting to fly away, but it was interested in what was happening further down the trunk. Another Galah, presumably its female mate, had emerged from a hollow there (see photos below). It looked as if the female was preparing the hollow ready for nesting. This was last Septemeber, right about the time they begin preparing nesting hollows for their next brood. I have no evidence that this pair went ahead and had a brood of young because we moved on elsewhere next morning.

The Galah is one of Australia’s most recognisable parrots. We have many colourful parrots in Australia – you can see photos of some of them by doing a search on this site. I have written frequently about parrots over the years and have included many photos of them. Some of these posts are included in “Further Reading” below.

Sulphur-crested Cockatoos in Lane Cove

Sulphur-crested Cockatoo

Sulphur-crested Cockatoo

One of Australia’s most recognised and common birds would have to be the Sulphur-crested Cockatoo. I have included a series of photos of this species in this post today. It is found along the north, east and southern coasts of Australia, and in Tasmania. It has been introduced to the south of Western Australia, and in New Zealand.

Large flocks

Throughout its range, it can often be found in large flocks numbering from a few dozen through to many hundreds. In my travels around different parts of Australia, I have observed this species in large numbers, especially where there is an abundance of seed for them to feed on, such as pastures. I have seen large flocks settle in paddocks, making the ground look like snow has fallen. When a flock is feeding on the ground, one or more birds will perch in a tree or on a fence post watching out for any danger. A large flock can also add colour to a dull grey looking gum tree when they all perch together.

Noisy birds

These birds have a very raucous call, and when a flock flies low overhead while calling, it is very hard to carry on a conversation. In some caravan parks we have stayed in where this bird is resident, a noisy flock can be an unwelcome alarm clock, particularly at first light when one wants to sleep in a little. In populated areas, this beautiful bird is often regarded as an unwelcome pest. With such an abundance of food, cockatoos can easily get bored and start chewing on timber work around houses and other buildings. Some of my readers have complained in the past about the destructive nature of this species. There is no easy solution to this problem because this species is a protected bird, like all of our native birds. If you are having a problem with cockatoos, please be in contact with your local National Parks and Wildlife office. It is an offence to destroy them.

Good pets

This species is also a common, long-lived pet for many people. They can be delightful pets and will often learn a range of words and phrases to mimic their owners. I am not familiar with the current regulations on keeping our native birds as pets, so it is best to talk to your local pet shop owners before buying a cockatoo as a pet. They are probably commonly available in pet shops in countries other than Australia. There should be no restrictions on keeping them outside of Australia.

The photos in today’s post were all taken of an individual in the Lane Cove National Park in Sydney. we were staying with our son spending time with our grandchildren during school holidays. On this occasion, we had a few hours break from the children, so we packed a picnic lunch and drove the short distance to the national park. Along the Lane Cove River, there are many lovely grassed picnic areas, complete with picnic tables and gas barbeques for the public to use.

Corellas v Cockatoos

Some people can easily be confused when trying to identify cockatoos and corellas. The three species of corellas in Australia are the Little Corella, Long-billed Corella and the Western Corella. Their ranges often overlap. I have even seen mixed flocks consisting of two species. Corellas are generally a little smaller and all corellas lack the yellow crest of the Sulphur-crested Cockatoos. The calls are also different, with the corellas’ calls being not as loud or as harsh.

A bunch of thirsty Galahs

Galahs near peterborough

Galahs near Peterborough

In my post a few days ago I posted several photos of several Mallee Ringnecks taken just north of Peterborough in the mid-north of South Australia. As I left the reserve where I took those photos, I drove slowly along the dirt road back towards the town. I stopped several times to take a few photos of the local birds.

This was early in March and we were having a particularly hot spell of weather. By the time I had left the nature reserve, the air was beginning to really heat up. I thought that it might be prudent to head back to my brother-in-law’s home and lay low during the worst of the heat. On my way home, I spotted several small flocks of Galahs having a drink at several old baths in the nearby paddocks. The local farmers had placed these bath tubs in their horse paddocks, brought the water pipe to the bathtubs, installed floats and thus provided a water source for their horses and sheep.

Naturally, the Galahs have endorsed this installation by also indulging in an early morning drink before the heat of the day to come. The second photo (the one immediately below) is unfortunately spoiled by the thin line of the fencing wire passing across the face of two of the birds. I did not notice this when taking the photo. It was only when I downloaded the photo and enlarged it on my computer that I noticed the wire. Such are the hazards of photography.

Some unexpected visitors

Sulphur-crested Cockatoo

Sulphur-crested Cockatoo

This morning I did a small load of washing. I actually enjoy doing this because it gets me outside and away from the computer for a while. It also has the benefit of getting me outside where the birds are, and with my eyes cast skywards I often see birds that I might have missed – like the time I saw a Peregrine Falcon overhead in the last moments of a very fast stoop. Awesome.

It also has the benefit of being able to hear more birds and I enjoy listening to all of their calls and trying to identify them without looking. This is a good way of honing one’s identifiction skills. After over 30 years of living on our little patch of mallee scrub here in Murray Bridge, I have become accustomed to our bird life and immediately notice something different calling. That’s what happened this morning.

I had just finished hanging out the washing when I heard a bird calling loudly. Two Sulphur-crested Cockatoos had flown in and landed in our of our pine trees. I had enough time to grab the binoculars and see that they were testing out some of the cones on one of the trees. Obviously the cones where not to their taste or not ready for eating because they flew off again a minute later. I didn’t get a photo so the one above was taken some years ago in Adelaide.

This was a significant sighting for the birds in our garden. I think my memory is correct – this is only the second time in over 30 years I have recorded this species in our garden. They are not usually seen here in Murray Bridge (80km east of Adelaide) though they are very common in the Adelaide region and throughout the Adelaide Hills zone. This is despite there being plenty of suitable feeding spots and nesting hollows, especially along the River Murray. I think I heard one screeching as it flew overhead a few days ago, but I was in the foggy early morning sleep zone. I initially thought it was a Little Corella, but now I am not so sure.

Perhaps these were some scouts looking for new places to live.
