Flying the Flag …

Some more life histories …

Australian Pied Oystercatcher 5B was in its first year when it was banded in 2013 so is now coming up to its 12th birthday. It has moved 286km from where it was banded and it is in a relationship!

Australian Pied Oystercatcher DV was in its second year when it was banded in 2011 so is now in its 16th year of life. It was foraging by itself 343km from where it was banded.

Sanderling LAX was banded just metres from where I found it 3 years later but far from being lazy it has probably flown further than either of the Oystercatchers because it hatched in the high Arctic and may have been to and from the breeding ground in the interim. That’s more than 11,000 km each way. They run a marathon every day as well. Their foraging style is to chase the waves out, snatch some invertebrates from the sand and run back in front of the next wave.

I found and photographed this trio within a few days of each other on the beaches around Port Fairy. They show the value of using flags that are readable in the field without catching the birds. I just fire away with the long lens as they continue about their business. Clearly the flags are not an impediment. Occasionally you can even read the numbers on the metal band for large birds.

I report the sightings with or without photos to the Australian Bird and Bat Banding Scheme. If you give them your email address they will get back to you and to the bander with the whens and the wheres. Here’s the link ABBBS. If you come across a dead bird with a band you can let them know the number on the band at the same link. It doesn’t matter if you can’t identify the bird – the band will. If you’re not in Australia there will almost certainly be another authority that you can track down on the internet.

The flags do kind of ruin the photos, they are not going to end up on the wall, but when it comes to arguing the case for conservation pretty pictures are trumped by hard data (except maybe for koalas, pandas and polar bears.)

A Parrot …

Richard of York gained battles in vain. A mnemonic for the rainbow, red, orange, green, blue, indigo, violet. The male Red-rumped Parrot would be a living rainbow if I could only find the indigo and violet. I’m sure there in there somewhere, maybe under UV light. Birds can see further into the UV spectrum than we can.

The Red-rumped Parrot, Psephotus haematonotus, is fairly common in open grassy habitats in South East Australia. It feeds on the ground. The female, sadly, is quite drab.

Fur Seal …

There is a seal colony on Lady Julia Percy Island about 22km from Port Fairy and occasionally a seal or two will pay us a visit. I found one this morning in the mouth of the Moyne River playing with a fish fillet that looked more like it had been donated than caught. The seal was shaking it and throwing it and occasionally chewing on it. It was having a grand old time.

The Australian Fur Seal Arctocephalus pusillus doriferus is a subspecies of the Brown Fur Seal. It is found around the shores of Bass Strait and Victoria, it breeds colonially on smaller islands. Adult males will weigh between 190 and 280 kg (420–620 lb) the girls are a bit smaller. The nominate subspecies is found around the shores of southern Africa.

Kelp Gull …

Back in Port Fairy now and one of the first birds I encountered was the other large Gull that is frequently found around Australia’s southern coast. Points of difference from the Pacific Gull in adults include

  • The bill looks less of a weapon
  • The bill has a red dot on the lower mandible only
  • The legs are a different yellow
  • No black band in the tail
  • A white margin around the black in the wing

Immature birds of both species have black bands in the tail, bill shape is then your best guide.

This guy had a vigorous bath then flew to the rocks to preen. Birds use their bill to distribute oil from the uropygial gland through their feathers.

Pacific Gull …

I toddled down to Ricketts Point early, it’s good to get there before the dog walkers to the extent that you can. It was cold and very windy. I didn’t see a dog and indeed most of the birds were hunkered down, head into the wind, reluctant to fly. The exception was a young Pacific Gull that was not going to let the weather stop it from repeatedly dropping a mussel from a great height. It was at a bit of a distance and I’m not sure whether it succeeded in smashing it open or the wind carried it into the water.

When it found itself in need of a new mollusc it came quite close to me. I was able to photograph it coming in and while it tried to prise a mussel from a hollow in the rock. While I approved of its choice of mussel it didn’t work well for the gull. After a while it flew off with an empty beak to try further away.

It takes four years for a Pacific Gull to arrive at adult plumage and even then there may be some buff feather margins to give it away as a relative youngster. By my reckoning this is a second year gull. Back in March it would have been browner overall and the bill base would have been white. Now (November) the yellow parts have good colour but the bill tip is near black not red.

Wallaby …

A walk around Griffiths Island, especially early or late in the day will almost always turn up a few Swamp Wallabies. As long as you don’t go too close they tend to just stand and look at you. Occasionally you might also see an Eastern Grey Kangaroo, they are not so tame. When they’re bounding along Swampies tend to keep their heads low and travel in a horizontal posture. Eastern Greys are more upright.

Despite their name Swamp Wallabies are not regularly found in swamps. An alternative popular name is Black Wallaby but they’re not black. Their scientific name is also a dud Wallabia bicolor since they are rufous, black and cream.

Aurora …

While I’ve been living in the tropics the sun has had periods of stormy weather, space weather that is. A son who lives in Melbourne has developed a bit of a passion for photographing the Aurora. They never reach as far as Broome and I will confess to a little jealousy.

You need a few things to get a decent aurora photo. The sun needs to get excited, the weather has to let you see the sky, the sky needs to be dark, the moon has to be not too full, a decent composition and a lot of luck. From the south coast of Oz you do at least know which way to point the camera – south. High ISO, longish exposure, wide angle and on a tripod.

My son follows the aurora forecast closely. For a few days now he has been urging me to get out there after dark but the sky has been clouded and Port Fairy has seen a fair bit of rain. Last night we won the lottery. His vantage point was across Port Phillip Bay, Melbourne. Mine was Griffiths Island, Port Fairy. My first composition included the light house and you can see the aurora if you know what to look for! I was on the phone to my son. He was describing a better developed event and encouraging me to get a good view of the horizon. So I scrambled precariously across the rocks and hunted for more compositions as the event increased in intensity. Please click on the first picture to see them at their best.

The aurora looks better on the camera than to the naked eye. It’s all about the rods and cones. Rods make up about 95% of the photoreceptors in the retina. They do the heavy lifting in low light and see in black and white. The cones come in three flavours (usually) and give us red, green and blue. The aurora is faint and in colour. The camera sensor is all cones (figuratively speaking) and shows us what is really there.

Meet Junior …

Junior is an Australian Pied Oystercatcher that hatched on Griffiths Island. You can tell this is a youngster by the brownish feather margins and relatively subdued colours on legs, bill and eye ring. He or she was probably one of two or three but there has been no trace of siblings over the last few days. Life is hazardous for young birds. Junior is probing for food for themself but is still very ready to accept food from its parents which are still a bit bigger.

When danger threatens Junior pretends to be a bit of seaweed while Mum and Dad run into the open and pipe up a racket, a distraction display.

Around the corner I came across L9. I last saw L9 three years ago and I’m pleased to see them still going strong. They were in a relationship back then but do not seem to be paired up presently. The Australian Bird and Bat Banding Scheme tell me that L9 was banded on 17th May 2011 and was 3 years or older at the time. (First and second year Oystercatchers can be aged by examination of the pattern of their moult). Banding occurred 288km away. They are now at least 17yrs old.

Port Fairy …

The migration to our summer feeding ground is complete. What we need now is for summer to follow us.

By my reckoning the distance the van has traveled from camp site to camp site is 8,727km. Add in the running around at the longer stops and the trip meter in the car stands at 12,350km. It took 55 days. The AOR Quantum+ performed well. Some minor maintenance was required and easily accomplished. It is now agisted in a paddock between here and Warnambool. Hopefully it will get some minor workouts during the summer. It has a small wound in its side courtesy of a narrow farm gate which will be fixed when I get around to it.

En route we caught up with good friends and family and visited some places that were novel and some old favorites. I thoroughly enjoy a good road trip and that was a great road trip.

Including the day before we left Broome and two days in Port Fairy I encountered 274 species of bird and the odd mammal and reptile, surprisingly few snakes. Spring in Victoria should soon fix that deficit.

Port Fairy is a coastal town of about 3,400 people. The south coast of mainland Australia was first put to commercial use by whalers and sealers out of Van Dieman’s Land (now Tasmania). James Wishart captain of the sealing ship The Fairy gave the place its name in 1828. John Griffiths established a whaling station on what is now Griffiths Island in 1835. We are staying in an old bluestone mill dating to 1860. It has been renovated since. It’s a two minute walk to Griffiths Island.

The town is packed to the rafters with heritage listed buildings and boasts the oldest pub in Victoria (so do a couple of other places so take that with a grain of salt). The port is suitable for fishing boats. Prior to the foundation of Melbourne and Geelong it was an important point of entry for settlers coming from the old dart.

Warrnambool is about 28km away and a much larger town (33,000 people). That’s where the commercial development went, leaving Fairy to be a quaint picturesque backwater.

When the Rainbow Bee-eaters and Rufous Whistlers head north for the winter so will we. At this stage our intention is to complete the loop around the coast.
