I really think you would save time by downloading a copy of Wings3D and having a go at making this stuff. There couldn't be a better first project than crude sticks and stones. Even if it takes an hour to figure out how to make a stone or a pointy stick, after an hour you'll have a pointy stick and an hour of modelling experience. Then the the plucked bird is a not-too-difficult next step, and before you know it you'll be making anything you need.

Wings has all the tools you need for a project like this and it is easy to learn: Start with a primitive and bash it into the shape you want. All the tools are in right-click context menus, so it only offers you tools appropriate to your current selection (rather than bewildering you with all the tools all the time). While a tool is active it gives you hints at the bottom of the screen. It has pretty good UV mapping tools too.
