Hi Philip


Quite right.  I was only reflecting on my own data and observations over the past ten or so years.  On the basis of that, it appears that this was a poor breeding season at my site.

Over the history of the GBS (although I don't know the last 10 years), sites with habitats for breeding of water birds have been few and far between. I would not think there is enough old data on water bird breeding to make a comparison. Such as I did in The GBS Report for the low level of breeding in year 2 (a drought year). Indeed  Appendix 2 shows the only water bird breeding records were Aust Wood Duck (24 records) & White-faced Heron (2 records) in the whole 21 years.

Reviewing my Garden Bird Survey numbers recently, it occurred to me that this season gone was a particularly poor breeding one for Jerrabomberra.  Our resident pair of Swans had a failed attempt in Spring and so far have not attempted an Autumn nesting.  We usually see around 20 young Swamp Hens per season, this year we had only 5 from two nests.  Moorhens produced only 2 young – usually at least 12-15.  No Coots produced at all.  Even our resident pair of Magpies produced only 1 young for the year and I did not see a Magpie Larks nest.  There were no Grebes nesting and only one family of Black Ducks. The exception has been Crimson Rosellas with significant numbers of green birds around.  I wonder if this poor season is reflected elsewhere?  A possible reason for the poor return on water birds may be the decline in typhus reeds around the local lake for which most birds rely on for nest sites.
