After piping yesterday's teeny tiny little frog, I figured the time had finally arrived to tackle this bird in a nest in the Ateco Cake Decorating Reference Manual. As you can see, there aren't any instructions, other than tip #'s printed near it (and I definitely needed additional round tips other than #5!).
You'll need a flower nail, a glue stick, parchment paper squares, a piping bag filled with white medium consistency royal icing, a #133 multi-hole tip, and round tips #8 and #2. You may also need a dusting pouch filled with a 50/50 mix of powdered sugar and cornstarch.
Pipe a spiral of icing with the #133 tip. Slide this square off the nail and stick another square to it.
