I just had the same experience like you did with your first zebra-finch: this strange little bird was sitting in front of the garage looking for food for the last couple of days. I did a little research on the internet and quickly found that it was a zebra-finch. Today it was exhausted and I was able to catch it with a small net. Since it is sunday today, the shops are not open so I must be quick tomorrow to buy some food for it. For the moment, I feed it with bread-crumbs and chicken-meal.
Thanks for your website. I will start building a big cage next week...
Greetings from Belgium,
