Cormorant and Darter Notes
Apart from the Stewart Shag which is ‘Red List 2019’ assessed as ‘Vulnerable’ all other featured species are ‘Least Concern’. Photographed in Australia, New Zealand and Trinidad. The Stewart and spotted shags are NZ endemics. In New Zealand, the pied cormorant is called the little shag.
Anhinga and cormorants, including shags, are medium to large birds. They do not have waterproof plumage, so they sit low in the water; the lack of buoyancy allows them to dive deep in search of prey. Cormorants congregate in groups while shags are more solitary coastal birds.
Little shags have variable plumage including black (dark morph) and white-throated morph as featured in the gallery.
Cormorant Behaviour Notes
Cormorants are cosmopolitan birds found mainly in temperate and tropical regions.
The gallery displays a short photo essay of a little pied cormorant fishing and swallowing its captured prey. I photographed this bird at Campden Inlet in New South Wales together with a bird drying out at Lakes Entrance in Australia.
Included in the gallery are other images that show various behaviours, such as cormorants drying out and preening. One of the flightless Galapagos penguin images shows a bird drying out; compared with other species wings it’s not difficult to see why it can’t fly. For size comparison, I’ve included an image showing and Australian Pelican and a little black cormorant.
Darter Behaviour Notes
Images show a male, female, immature (juvenile) and young Australasian darters pruning and drying out. I photographed the birds at two locations: Kakadu National Park and Fogg Dam in Australia’s Northern Territories. One image shows a predator (white-bellied sea-eagle) and potential prey (Australasian darter) perched in the same tree at Kakadu. The eagle had been fishing so probably not interested in the darter. In Singapore, I’ve seen these eagles attack and try to take grey herons which are slightly larger and heavier than Australasian darters.
