I found a similar bird on the web somewhere and my attempt ended up as a modified slice form. Made a mistake by starting out too big: slice forms don't reduce well at all! I had hoped the 150% reduction in attached file might fit in a card (tabs would need to be added) but it is very very difficult to put together now. However I was quite pleased to discover the large version would stand on it's own. Birds are held together with a dot of glue at beak, top of head, and back. Bird on slice form base is supported with a double layer of paper glued inside tree trunk.
