Hi, my name is Daan Vreugdenhil; I have a PhD in conservation ecology and dedicated my career of 4 decades to conservation, for which I visited more than 80 countries and learned 6 languages. I have always felt that conservation is a passion, not a profession.

As a child, my father would take me on his bicycle into the meadows in Holland, where he taught me to identify birds and plants. I caught frogs, butterflies and lizards as pets. As a teenager, I joined a youth club for nature study; every weekend, my fellow club  members and I we rode our bikes to study in nature reserves. Little wonder, when time came, I studied ecology and natural resources management.

I never got over my love for nature, wild places, forests, deserts and wild animals. I still love hitting the trail, kayaking down a river, the wind in my ears when skiing down a slope or riding my bike. Often people ask me if I don't get tired of traveling. How can one ever get tired of the beauty of the bright colours of Indian Summer (autumn), the thrill of an eagle soaring in the sky, the thunder of Iguaçu Falls, the smell of flowers, a jubilant Sky Lark in the spring, Elephants roaming the plains. My entire life has been dedicated to nature conservation.

This website - the result of 15 years of unpaid work - is my gift to you, so you can follow me in my passion and carry on the flame of conservation. If this website in any way was useful to you, then I invite you to make a donation to the  Adopt A Ranger  Foundation. The Adopt A Ranger Foundation is my latest contribution in my quest to save 10% of our planet as a home for birds, other animals and plants. Help spread the word with your "FB likes", etc.

Backyard birds and you

Millions of people like having birds in their gardens as part of the beauty, fun and entertainment in the immediate surroundings of their houses, and right they are! No matter if you have just started living in your own place, have your own nest full of little or taller chicks, are enjoying your home by yourself or are an empty nester, birds are a the crown jewels of your garden, a constant source of entertainment, giving you fun and exiting moments every day of your life. Did you know that in the US as more than 60 million people do something to attract birds to their gardens or houses? No doubt you are one of those people and thereby you are a birdwatcher! You may never have thought of yourself being one, but hey, you put up a birdhouse or birdfeeder to watch birds come to your garden and house. So......, you are a birdwatcher!

With our huge website giving lots of technical information, I thought I really should pay more attention to the millions of people who don't keep up a birdlist, who don't spend their weekends trotting through the woods. If you like looking out of your window and see birds on a birdfeeder, enjoy little birds busy around feeding their young, then this section of the website is for you. If you go to school, then I like you to feel that this part of the website is specially for you.

I just started this section and it will take a while until all the pages have been written with good information. I still need to get good pictures of birdhouses, birdfeeders, designs and ideas. There are many website selling birdhouses and feeders, and quite frankly I am appalled by the prices of the products on most sites. So over time, I hope to help you discover affordable ways of making your own birdhouses and bird feeders. At first you will find some links to sites, that I consider worth reading and consulting, but over time, most of the information will be from myself. But I can't do it alone. I need your help to help the millions of bird friends to help our feathered friends. Therefore, I would really appreciate if you could send me pictures and suggestions and comments on birdhouses and birdfeeders.. Not to do me a favour, but to share your pictures with others and help them with your ideas and pictures to get the joy of having those marvelous joyous feathered friends around their houses. Sometimes it takes a while, but so far I have always answered emails sent to this website email address at the bottom of this page. I hope you send me your ideas and pictures so it can show them on this website. As you can see, this is not a commercial website, and your pictures would be enjoyed by countless other bird friends, as we enjoy as many as 1 000 000 visitors per year and the numbers are growing at a rate of more than 30% per year! 

For bird friends in the USA, there is a great web project to help follow or monitor how breeding birds are doing: Anybody is welcome to participate in the project and share with scientists how the birds in your birdhouse have been faring. In turn you receive information on breeding success from others.


How to attract the 30 most common Australian backyard birds: Ideas and suggestions on how to attract birds to your garden

In the table below you find dimensions of birdhouses or nest boxes for a number of species of Australian backyard birds, although not all are backyard birds. The data come from different authors. These dimensions are not cast in stone, and when size ranges are given for the entrance diameter, I would start out with the narrowest diameter. If that works, then that is best. The smaller the hole, the safer the bird family. The sizes of the internal diameter and the length (height of the nest box) are probably not all that critical. So for those sizes, if the size seems rather large, chose the smaller one, or visa versa.
