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.)

Oyk …

On a more serious ornithological note, the fair city of Broome (population 15,000) looks out over Roebuck Bay, Australia’s most important site for the waders, outnumbering the humans many times over. In Australian (and English) usage waders are birds in the order Charadriiformes. Americans tend to prefer the term Shorebirds and if you say wader they think of herons and such and it’s possible they might have a point. Herons do a lot of wading. Some waders do no wading at all, not all shorebirds live on the shore, but most do. But I digress. The Broome Bird Observatory is the hub of considerable research into the charadriiforms. So it was that on 1st December 2002 members of the Australian Wader Studies Group were in the field (on the beach, actually) using cannon nets to catch birds.

Among the catch that day was an Australian Pied Oystercatcher. It was weighed, measured and closely examined. It was in its third year of life or older. Smart ornithologists can age first and second year Oystercatchers by their moult. It went from being an anonymous Oyk to Oystercatcher 101-07877. Thus if it were encountered again something would be learnt about its movements and survival.

I was not in the field with the AWSG that day in 2002 although I have enjoyed that privilege on other occasions. I was on Gantheaume Beach on the 11th of August 2025 when I met 101-07877. When it faced west I was able to make out the first three band numbers, when it faced east I was able to get the last three. I had no luck getting two numbers in between.

I reported my sighting to the Australian Bird and Bat Banding Scheme. They had records of two Pied Oystercatchers 101-XX877 but the other one is also carrying a coloured flag. Thus we know the identity of this particular little bird, found alive and well just 20km from where it was banded 22 years 8 months and 10 days earlier. Its age is now 25 years or more.
