The rain has lifted and we are experiencing a taste of fine, winter weather. Celebrating the dry weather the black butcher birds are at their melodious best and from the first glow of sunrise duets of song ring out across the mangroves.
The Black Butcher Bird is a master of mimicry and the songs of over 39 different bird species have been documented as copied by the black butcher bird.
However, this bird does not stop at just mimicking other birds he includes in his repertoire the sounds of lawnmowers, reversing trucks, telephone rings and the human voice. Scientist believe the black butcher bird hears sounds in the same manner as we do.
It is believed the bird song is used to mark out territory as the black butcher bird is sedentary. Song is also used to establish pair bonding and it is with their courtship songs the black butcher birds achieve their ultimate vocalisations. The song is often synchronous and the unison duets are performed with the head tilted back and the chest and breast feathers puffed out. The pair react to each others performance and their pleasure will often be demonstrated with a little 'dance' on a branch only to continue their song which resound across the forest in the increasing light of dawn. What a wonderful way to greet the day!
The black butcher bird nests between September and February and they build a bowl shaped nest consisting of sticks and twigs lined with rootlets. The nests are built in forked branches of tall paperbark trees between two and ten metres above the ground.
The male rainbow bee-eater has two extended central tail feathers. The female has shorter tail feathers.
The native nutmeg Myristica insipida is fruiting at Coquette Point. This is unusual as this tree normally sets fruit in Spring.
Rainforest wonders.
Ian Laidlaw from his property on the Palmerstone sent me
some amazing fungi photos. The rain has even frustrated
hardened local like Ian. Thanks for the photos Ian.
Lots of little green frogs are hopping around the nursery
and I noticed a red mite on some of the frogs. Can anyone
identify this creature and is it a problem or a food for the
frog?
Bill Farnsworth has identified the mite on the frog as a 'red velvet mite' an interesting little critter. Thanks Bill.

Hi Yvonne,
ReplyDeleteI believe that the red mite on the frog is a Trombidium, also known as a velvet mite. They are parasitic on small animals, but don't usually harm the host. http://en.wikipedia.org/wiki/Trombidiidae

The new spider you found is actually not Porta fimbriata, it is a Lichen Huntsman (Pandercetes gracilis). Still cute though :)
