Walking Beeliar Wetlands Part3

This section of the walk was done two halves. Not because the walk was going to be too long! But as I do shorebird counts each winter and summer at Thomson’s Lake and Kogolup Lake. Doing shorebird counts takes more time as you need to get a good view of all (or nearly all) of the water birds at the lake. These counts for BirdLife Australia’s National Shorebird Program.

So on the 7 July I stepped off where I ended at the south end of Yangebup Lake to walk Kogolup Lake and Swamp and on 7 August I went around Thomson’s Lake.

The walk trail is on the west side of Kogolup Lake.

There were a few wild flowers in bloom but in July there are only a few flowers out. The birds were busy feeding in the bush but there was not many waterbirds. In late winter and early spring there is lots of water in most of the lakes and the water birds spread out over more wetlands.

There were a lot of Black Swans on Kogolup Lake.

In total I saw 38 species of birds with the most seen being 137 Black Swan, 67 Australasian Shoveller and 52 Australasian Swamphen. It was very pleasing to see and hear a Fan-tailed Cuckoo calling from a high tree branch.

Kogolup Lake has a lot of bullrushes growing on its western side.

The survey also recorded 26 Rainbow Lorikeet, only 1 Australian Ringneck parrot and no Red-capped Parrots. This is very sad reflection of how this invasive lorikeet is taking over habitat and pushing our native parrots out of the Perth area.

The path walked along the west side of Kogolup Lake. This has only recorded half of the walk as the app went a bit crazy on the return journey!

Thomson’s Lake is a Ramsar Wetland of International Importance and a much bigger open wetland than the twin wetlands of Kogolup.

Thomson’s Lake in early August was filling up but still had a large damp edge.

As the lake was still very shallow, the water bird diversity was quite poor. But there was 270 Black Swans present with a number of them constructing large nests. Virtually all of the Typha has been removed from the lake in the past few years and it is interesting to see the swan nests out in the open. This may make predation of the nests more likely.

There are hundreds of Western Grey Kangaroos in the Thomson’s Lake reserve. They often feed at the edge of the lake.

A total of 39 bird species was recorded for the National Shorebird count at Thomson’s Lake. The summer shorebird counts always have more species and a greater number of water birds.

The walk taken at Thomson’s Lake is marked in red.

It was interesting that at Thomson’s Lake there was only 6 Rainbow Lorikeet recorded, while 6 Australian Ringneck Parrots and 2 Red-capped Parrots were recorded. This wetland is surrounded by more bush and market gardens, rather than suburban house blocks.

Thomson’s Lake has a walk path that goes around the lake, however, in late winter and early spring you need to wear rubber boots as a section of the path is covered in water. This is because at this time of the year a drain from the east of the lake is flowing into the reserve and the water goes over the track.

There is one section left to walk but I will not be have time to do this section until some time in September. Now that the wildflowers are out I am very busy looking for new wildflower sites and species that I haven’t seen before. So I suspect that my next blog post will be a wildflower one! It is looking like a good wildflower season!
