Norfolk Island - White Tern

April 7th 2011 06:17
... and some young birds live precariously ...

White Terns, or Fairy Terns as they are commonly known, are a small, brilliant white sea bird, with a long, black beak and big black eyes. Their eyes look big because they're ringed with black.

We were walking the track in Rocky Point Reserve on Norfolk Island when our attention was captured by two White Terns who were paying attention to each other. They were on a bare branch of a Norfolk Island Pine and appeared to be carrying bark in their beaks. We assumed they were building a nest, but the branch seemed an unlikely place.

A few days later we were on a walking tour in Norfolk Island National Park when we saw a White Tern sitting on a thin branch. We were very interested to hear the Tour Guide explain that White Terns often lay their one speckled egg in a slight hollow on a branch of a tree, or in the fork of a tree where two branches meet. This Tern was a regular to this spot. Of course the egg and later on the chick are in a precarious situation, but the chick has well developed feet to help it cling to the branch to enhance its chances of survival. If an egg or chick is lost the female soon lays another egg.

As White Terns don't build nests, the pair we spotted in Rocky Point Reserve were probably courting. Perhaps they were lining the hollow with bark?
In the White Tern world both parents incubate the egg and the parents feed their young for up to two months.
White Terns feed themselves and their young on small fish.

Tortoise on a Lily Leaf

This is one of my favourite photos.

While visiting Vietnam we were wandering past a pond, amidst the gardens in the grounds of the Presidential Palace, when my eye caught sight of this small tortoise resting on a lily leaf in the pond.

This blog shows the life cycle of a butterfly called Doleschallia bisaltide, commonly known as Autumn Leaf. It is found in some parts of Asia and Australia, and has been found in Singapore for about ten years.

This caterpillar was found in a garden in Singapore and its various stages of development photographed, giving you the privilege of observing its transformation from a caterpillar to a butterfly.

The caterpillars grew till they were about 7 or 8 cm long. Then eventually, each caterpillar climbed to the highest point it could find and attached itself, tail end, by spinning some find thread, and hung upside down. The caterpilars all chose the evening to attach themselves, and hung there, upside down, overnight. While hanging, the caterpillars curled themselves around, as in the photo below, and seemed to scrunch up like an accordian, shortening in length and filling out width-ways.

In the morning, the caterpillars shed their skins. They all wriggled violently during this process, as the skin came off, making it very difficult to photograph.

The skin fell off, discarded, leaving a raw-looking, wriggling mass (the chrysallis) hanging.

Over the next day or so, the covering of the chrysallis hardened and darkened.

About one week later, the colour of the chrysallis darkened, and the next morning there was a butterfly.
