Brigid Taylor Jackson named this bird this morning on Facebook ‘Haaa de Haa’ and that is more or less exactly the sound of the shrieking once high up in the air (are they afraid of heights Brigid or are they laughing at us?). The common name is Hadeda or Hadada Ibis (Bostrychia hagedash) and although originating from Sub-Saharan Africa you see them all over here in our village.
See also this YouTube. And this is my version:
The Cape Cormorant (Phalacrocorax capensis. Fam. Phalacrocoracidae) is a common sea bird along the Southern coast of South Africa. Usually they sit on rocks along the shore. Fairly easy to approach but not closer than 7-8 meters before they get restless and migrate to another rock.
I made several pictures of the group and processed these, except for one image (=as is) in different ways in Photoshop. Not sure which photo to choose for this post so I publish them all.
