Seals and their habits

A group of seals is seen regularly around Red Head peninsula on the New South Wales South Coast - most often drifting near the rocks with their fins erect to adjust body temperature. Recently, and for the first time, I saw several seals basking on the rocks, and also some signs that they may have been feeding on seabirds.

The seals at Red Head have previously been identified as Australian Fur Seals.

This is the rock on which the following photographs were taken, all within a few metres of each other at the flat ridge near the top of the rock.

Remains of a seabird, its body largely eaten.

A hollow about 75 cm diameter forming a ‘‘nest” lined with feathers. A nice size for a resting seal?

Deposits - regurgitated or scats? with a high content of feathers.

The Cuckoos Arrive

We heard the first Koel calling in our area of Sydney about two weeks ago and since then a number of cuckoos have arrived. At Bendalong on the NSW South Coast there have been several Channel-billed Cuckoos, as well as Common Koels. A first Fan-tailed Cuckoo was sighted nearby. On the Bendalong headland there was a group of around six cuckoos squabbling and calling; from fleeting glimpses, the trilling and chorus of descending calls they were identified as Shining Bronze-Cuckoos. The very poor picture below appeared to confirm this identification.

What appears to be a Shining Bronze-Cuckoo sighted at Bendalong on the NSW South Coast. It was one of a group of six squabbling and calling together.

More "Bush Birds" in South Coast, NSW township

My garden bird species list in the coastal township of Bendalong is still growing as birds adapt to changes due to the Currowan Bushfire and the heavy rains that have followed.

The Brown Thornbill (10 cm) is the most common of the “Small Brown Birds” that frequent the Shoalhaven area and is currently visiting the garden more often than before.

Figbirds are reasonably common near the coast during summer but this female and her mate were the first I had recorded.

The Eastern Spinebill is a regular visitor but it has been having a tough time recently due to a build up in numbers of Little Wattlebirds, who compete for the nectar from these Salvia flowers.

The Eastern Koel is a regular over the summer. This rather ragged young male is losing the last of his (brown) juvenile colours. Together with the Figbirds the Koels should be making their way north at this time of the year. Koels, being a cuckoo, are often raised by Red Wattlebirds in this area but this is a species that has almost disappeared locally losing out to the Little Wattlebirds after the bushfires.

Bushfire devastation made worse

The need to protect trees remaining after the Currowan bushfire seems obvious. However for some the bushfire has given reason to cut down more trees.

On returning after the NSW lockdown to two survey sites in Conjola National Park I was dismayed at the first to find a large shelterbelt had gone and that the roadside treeline had been cut back a further ten to twenty metres from the road. This occurred some time between June 2021 and October 2021, during the lockdown period - over a year and a half after the fires!

The Bendalong Mountain Road Birdata survey site extends from this point close to the Bendalong Road corner to the far corner 200 metres down the road. On the left hand side of the road a shelterbelt of mature eucalypt trees has been totally removed and replaced by the barbed-wire fence. On the right hand side of the road the treeline has been cut back ten to twenty metres from the power lines.

At the second site on nearby Nerringillah Road the trees had again been cleared a further ten to twenty metres from the road. In addition there has been extensive clearance of trees along the Bendalong road, for approximately two kilometres the bush has been cleared 10 to 20 metres back from the road.

On enquiry it seems that this clearance is legal. There are a number of regulations that might have allowed removal of these trees. Electricity companies have powerful “rights” to clear land where there are above-ground powerlines. Under the Electricity Supply Act 1995 and even the the Biodiversity Conservation Act 2016, they have an absolute power to remove trees.

Then in August this year the NSW government introduced new rules that allow landowners to clear rural land within 25 metres of their boundary with very few restrictions; the Rural Boundary Clearing Code under the Rural Fires Act 1997. If the land has not been previously protected there is little requirement to consider environmental impact and no need to offset the loss of vegetation.  

The Bendalong Mountain survey site is a standard Birdata two hectare site for conducting 20 minute surveys. This older map of the site was prepared on Google Maps. It shows the shelter belt at the road side and the bush on the left hand side, part of Conjola National Park.

The reason for this clearing is likely to be given as “ bush fire risk management” but it seems highly unlikely that these clearances would have protected anything or in any way changed the course of the devastating Currowan fire last year.

I started monitoring these survey sites after the fires, to get an idea of bird numbers in the central area of Conjola National Park. At that time the park was still closed so road-side sites were the only way you could do this.

There are not a lot of birds in this area, at least this has been the case during the surveys I have done since the fires. The most recent survey, conducted after tree removal, counted eight and seven total birds on the sites respectively in a 20 minute count. It will be difficult to see if the removal of trees has any effect on bird numbers in this small area. Nevertheless clearances like this are part of the insidious decline in habitat, responsible for the decline of bird species generally.

Beach-side survey sites

A bird survey by the sea last week had some unexpected visitors. A group of Australian Fur Seals basking close to the rocks and then Humpback Whales on their trip north.

At first glance it looked like seaweed dancing in the waves - but it was a group of twelve or more seals - close to the rocks on this South Coast NSW beach.

The Australian Museum identified the photos as Australian Fur Seals and said that they were actually cooling off by raising their fins in the air - their fins have blood vessels close to the surface forming useful heat-exchangers.

Two (or more) Humpback Whales pass close to the beach on their way north to warmer waters.

This young Australasian Gannet flew over while I was taking the seal photos.

NSW South Coast Bush Shows Green Shoots

Ten weeks after the bush fire there are green shoots to soften the bleak colours of the burnt bush. The heavy rain of the past few weeks has been very timely but a lot questions remain about the fire’s impact on wildlife.  Bird species numbers on the bush survey sites I monitor are not showing any increase since the fires. But this week a flock of Thornbills feeding in the fresh green foliage increased the total number of birds counted.

The “Path” site photographed in my January 28 blog showing the magic effect of time and rain. Unfortunately there were very few birds to match its green appearance.

There do seem to be more birds around the townships and some less common birds have taken up residence. The photos below show some of the newcomers.

This Wonga Pigeon has taken up residence in the vegetable garden, here seen exploring the compost heap.

Another pigeon, the White-headed Pigeon has turned up, not often seen in these coastal towns.

This Glossy Black-Cockatoo was at Garrad Reserve, Narawallee.

NSW South Coast Birds after the Bush Fires

The trepidation of our trip down the Princes Highway from Nowra was relieved to some extent by green patches along the burnt out roadside. Then turning onto the Bendalong road this devastating scene; these barren and charred remains.

Bendalong road, January 2020

The seaside towns of Bendalong and Manyana are intact despite being burnt on all sides, a tribute to the firies. Even the bush along the Bendalong beach-front has been burnt out. The dawn chorus was subdued, a pair of Magpie-larks and then a Sulphur-crested Cockatoo’s screeching. The numbers of town birds are well down; ones or twos where previously there had been a dozen.

The “Path” Birdata bird survey site, 95% burnt out.

The two Birdata Survey sites I set up in 2017 were burnt so I wanted to see how bird numbers had changed. On the “Path” site survey I found it a relief to hear a lone Little Wattlebird calling, later to be joined by two Lewin’s Honeyeaters and then some Striated Thornbills. On the “Bush Track” it was fifteen minutes before the first birds arrived; two Eastern Yellow Robins and then a Rufous Whistler.

The two sites were already badly affected by drought and bird numbers dropped off during 2019, as seen from the survey results below. The birds are going to need all the help they can get to recover from this double whammy to bird life.
