Preheat the oven to 235°F (113°C). Line two baking sheets with baking paper. Set aside.
Add the egg whites and cream of tartar to a mixing bowl and beat with an electric mixer until the mixture is foaming like soap bubbles.
Start adding caster sugar 1 tablespoon at a time, letting it incorporate after each spoonful until the sugar is all added. It may take 10 to 15 minutes. The meringue should be thick and glossy, and the sugar dissolved. It is ready when you pull the beater away and a stiff peak remains and you can rub the mixture between your fingers with no gritty feeling.
Mix in yellow food coloring to desired color.
Put a 1 cm plain tip on a piping bag and a leaf tip on another piping bag. Spoon 3/4 of the meringue into the first bag and 1/4 into the bag with the leaf tip.
Squeeze mounds of meringue onto the prepared baking sheet. Each will have 2 layers, about 1 1/2 inches in diameter on bottom and slightly smaller on top. Then take the leaf tip and make wings on either side.
Push 1 orange carrot sprinkle or orange heart shaped sprinkle into the front of each meringue to form the beak.
Bake for 55-65minutes or until meringues are firm but not browned. Turn the oven off. Allow the meringues to remain in the oven until cool. Remove from the oven.
Dot on eyes with the gel frosting, keeping them small. If using a icing pen draw the eyes on.
