The pattern is by Berroco and is available free here. The bird is only about 3 inches tall. I used aran weight yarn but the pattern calls for worsted weight yarn so should result in a smaller bird.
I made the beak of my bird shorter and fatter than the pattern because when I originally knitted it up, it didn't look right. The new beak fits just perfectly. The body is knitted in the round - so no seams. The wings and tail follow the same pattern. Quite quick to knit and very cute.
