We visited the breeding colony on the reserve for a second time this year to ring and colour-ring chicks. We managed 10 Cormorant and 3 Heron chicks before the weather began to turn. The fortunes of the Herons didn't look too promising with some mortality noted and none of the chicks vomiting on us, suggesting they did not have full stomachs. Small chicks and eggs could be seen in a couple of inaccessible nests, but overall it looks as if it will be another poor year for Herons.
