After very recent heavy rainfall (48 mm on 9 April) water levels in all lakes, smaller water bodies and the dam have risen significantly. The large freshwater lake is providing favorable habitat for diving feeders including Little Pied and Little Black Cormorants, Australasian Grebes and Hardheads, all in increased numbers compared to last month. This especially applies to the two species of cormorants comprising a total of 41 birds, by far the largest number ever recorded in this lake since these surveys commenced in March 2007.
The saltwater lake is now pink, but supporting very few birds.
The abnormally low number of land based birds encountered during the survey, such as Superb Fairy-wrens and White-plumed Honeyeaters was most likely due to the strong south west wind.
- In mid March on the Large Freshwater Lake George saw a large circle of Little Black Cormorants feeding together, with a number of Silver Gulls picking up food in the centre. The prey was considered to be Mosquito Fish
- An estimated 10 to 15 Fairy and Tree Martins were seen flying around the western end of the Large Freshwater Lake with the 150 Welcome Swallows in very windy conditions. The majority were Fairy Martins, identified by their light brown heads as they flew rapidly by, but a small minority had black heads. This is by far the most martins ever seen in the park. Previous sightings, last recorded in October 2016 (a single Tree Martin) were of single or two to three birds.
- A pair of Flame Robins seen today in the new area along the Yarra River. One bird was a female, and the other appeared to be an immature male in the very early stages of developing adult plumage.
