I checked Marnix’s cormorants this morning.  They were as below, roughly as he described.




A useful first resort for breeding info is Steve Wilson’s book, which for this species states: ‘Breeding has been recorded on the Molonglo River above the lake, the largest colony reported being 40 nests’.  This seems such a large number that one is inclined to wonder whether there was not some confusion with Little Blacks, but there it is.  Apparently on the basis of that entry, the species is labeled ‘Common resident, breeding in suitable habitat’ in the ACT checklist.  The observation would need to have been between 1999 (SW book) and 1992 when the ACT Atlas stated ‘’no confirmed breeding records for the ACT’.

I was surprised today to see 2 Great Cormorants nesting on a small pontoon in the main pond at Queanbeyan Sewage Ponds. Both sat quietly on separate large nests made of sticks for the half hour I observed them. Is this a first? Its the first time I have observed breeding in the ACT.
