The Mudlarks

The Mudlarks is a local bird-watching group of Mudcrabs that regularly surveys the Cooks River Valley. We meet once a month (on the 2nd Tuesday morning) to perform a 2 hour survey of birdlife along the Cooks River. We started in early 2019 and have collected birdlife data each month. We survey 2 different routes so as to get a broad picture of the birdlife for different environments. We alternate these circuits monthly.

The Wave Rock circuit goes from the Lang Road footbridge, east along the Earlwood side of the river and returns along the Marrickville Golf Course side past Wave Rock..

The Boat Harbour circuit goes from the Lang Road footbridge, west alongside Ewen Park and Boat Harbour to the Flourmill then crosses to the Cup and Saucer Creek wetlands before returning along the south bank of the river to the Lang Road footbridge.

Survey data for the 2 survey routes since Feb 2019

The Mudlarks record all species confirmed along with the count and other useful information. We are lucky to have pockets of well used breeding areas for our waterbirds and other species. By monitoring these sites regularly we are able to gather information regarding the arrival of new species and the impacts of Mudcrabs activities along the Cooks River.

Doug takes each months survey data and updates a detailed cumulative spreadsheet (link below). The birds are divided into a number of groups that represent the differing habitats that are provided along the Cooks River namely Waterbirds, Birds of the Woodlands and the highflying Birds of the Open Skies.
We are lucky to have talented ornithologists, nature photographers and eagle eyed enthusiasts (both experienced and novice birdwatchers) on the surveys.
Now we have a few years data and the bird population dynamics are appearing and these trends are reflected in the cumulative spreadsheet.
