End of the Line

It's that time of year when some of the big Golden Orb Weavers are in their last days. They neglect their webs and do not eat very much. Males are not found and females descend to the ground to lay their eggs. In addition, Black Butcherbirds seek them out and pull them from their webs. During previous weeks, the spiders seem to avoid being picked off by the birds. Perhaps, the untidy webs are a giveaway for the spiders late in the lives of the orb weavers.

They are beautiful spiders when you see them up close. And they can see you. They are quick to dart to the we's edge when you approach.

Cassowary Update

The three youngsters are still growing and they still continue their characteristic peeping. This becomes more enthusiastic when the food source is is to their liking.

But the end is neigh. The chicks are just about the right size for their lives to make the next change. That occurs when Pops decides enough is enough and he drives them away. This seems sad because the chicks do not seem to understand what is going on with their father. He was protective and attendant yesterday but today he is antagonistic. Actually this behaviour may be initiated by the female when she comes into season.

 Nice garden bird, eh?

Some colours beginning to appear and the wattles are developing

New Book

A new book has appeared on the scene and most people reading this post would probably not be aware of it because it is published privately.
Lynette Esnor has produced a very handsome volume, number 3 in her series. This one features birds of Northwest Queensland. The other volumes include #1 The Wet Tropics, Queensland, #2 The Gulf of Carpentaria, Queensland. Another volume is in the offing and the topic will be the brids of the Cape York Peninsula, Queensland.

The book is comprehensive in the sense that it, and the other volumes contain an introductory section  featuring the History of Bird Evolution, Anatomy and Physiology, Adaptations (in considerable detail)Torpor, Feeding Habits, Preening, Feather and Plumage, Senses, Seasons, Mating and Nesting, Family Life, Migration and Distribution. Most of these topics are generally not covered in other volumes and they are of interest to the casual birder. A glossary and comprehensive index are also included.

The volume is attractively presented and features Lyn's photos in the 205 pages. Detailed notes accompany each species.

My Bird Obsession is published privately and can be ordered from Lyn at her email address: Lynette Ensor
