I really didn't want to take the ornaments off and put them away.
However, there are some very cute bird ornaments I wouldn't mind knitting. I really like these round little fellows from Chiwaluv Amigurumi Critters. I think the only thing stopping me is I don't have DK or other lightweight yarn in the right colors.
There is also this little adorable bird from Knitting For Your Home.
Audrey's Knits on Ravelry gives you a lovely flying bird.
Another dove-like bird, one I like from Knit Cafe Toronto.
Yet another dove pattern. I don't want to be accused of leaving one out! This is Picasso's Peace Dove from Nicole A. Davis .
You'll have to think about what you want in your dove in order to choose a pattern.
With a little more effort you can make these felted birds, designed by Marie Mayhew and available at Marie Mayhew Designs
This little guy isn't very realistic--he doesn't even live on my continent--but he's definitely very cute and cheerful. He'd be great to find waiting for you on a package.
He comes from Jacquie Turner. Here's a whole flock:
Some enterprising knitters made some clever variations. I had fun looking through them on Ravelry.
