Lovely weather for ducks!

We’ve had lovely weather for ducks in the last week – ever since I posted about last year’s rainfall, in fact, although I don’t think my post was the cause. I visited the Town Common on Wednesday morning and enjoyed sloshing around in intermittent drizzle before the really heavy rain started about 11 o’clock. Everything was beautifully green and the waterbirds were feeding happily.

Most of this group were Cattle Egrets – more precisely Eastern Cattle Egrets (Bubulcus coromandus) – which are pure white in non-breeding plumage and rufous in breeding plumage. The bigger pure white birds are Intermediate Egrets (Ardea intermedia).

I met an old friend who was very excited at seeing a Pied Heron amongst them – a really rare sighting, she said, but I had to admit that I don’t know enough about birds to fully appreciate the rarity. I did get a (bad) photo of the bird, however.

For better photos of the Pied Heron (Ardea picata), you could visit Birdway.

The other unusual sighting was a Jabiru aka Black-necked Stork, Ephippiorhynchus asiaticus, fully-grown but still in juvenile plumage.

Also seen in this short trip: small flocks of Magpie Geese were moving around; a single White-faced Heron and a few White Ibis and Spur-winged Plovers amongst the Cattle Egrets; Crimson Finches, a greenish honeyeater and a Dollarbird near the Freshwater bird hide; a couple of terns; and (heard but not seen) a Pheasant Coucal (links are to older photos on this blog).

Ducks? I’m sure there were but I can’t remember them.

I think I will have to start making lists like real birders do.

Jacanas (family Jacanidae) have adapted to, and specialised in, one particular kind of habitat, shallow freshwater lakes and ponds with floating vegetation. They live right across the tropics, with various species in South and Central America, southern Africa, India and South-east Asia through to New Guinea and northern Australia. We only have one species in Australia, the Comb-crested Jacana, Irediparra gallinacea, and it is found in northern and eastern coastal areas from the WA-NT border to about Sydney.

They were new and exotic to me when I first came to Townsville from Victoria but are not too uncommon here; I’ve seen them on Ross River, for instance, and on the Town Common, and I spotted this one on the lagoon in Anderson Park, one of Townsville’s three Botanical Gardens. They don’t move very fast but they can still be hard to observe because they tend to stay well out from the edge of the water, where they are safer.

Their adaptation is in their feet. The toes are enormously exaggerated and spread their weight so widely that they can walk on floating lily pads or other water weeds and exploit the food available on them or just under the surface of the water. The penalty is that they are somewhat clumsy when walking anywhere and can’t fly as well as they otherwise might.

The Jacana is not very big – its body isn’t much bigger than the lotus bud behind it.
