Goliath and Grey Heron

© Gerda van Schalkwyk

Gerda's comments:

"During a recent visit to Lake Panic in the Kruger National Park we noticed a Goliath Heron Ardea goliath and a Grey Heron Ardea cinerea nesting together. The Goliath Heron would fly down from the nest to collect twigs which were then presented to the Grey Heron. They exhibited what would seem courtship behaviour and the Goliath Heron also got on top of the Grey Heron as if to mate. They repeated this behaviour over a number of days.

Comment from bird behaviourists would be appreciated as we think this is unusual behaviour."

Saw the same two at Lake panic on Thursday but although the Grey Heron was having a jolly good time on the back of a hippo and not on the back of the Goliath.

I directed Andre Botha of EWT to this post and he said: 
 
In my opinion, the Grey Heron (sitting on it’s nest) is clearly alarmed (raised crest) as the Goliath is wanting to make a snack of the nest contents, i.e. eggs or chicks. Look at the very interested glint in the GH’s eye!

Please refer Andre Botha to the following photos. I was with Gerda at Lake Panic, and I can confirm that that these two building a nest together, and that they Goliath Heron was most certainly not interested in making a snack out of nest contents! These two were clearly very interested in each other, and not in eggs! I would appreciate some expert opinion on whether this is normal behavior between different heron species. These photos clearly show mating behavior.

people, I have posted the links Willie provided in the main body of the blog post as the comment box automatically makes links unusable.
