Of course! But first, you say, what is Draw a Bird Day? According to Wikipedia, it started in the U.K. in the 1940, takes place on the 8th of April every year, and…you guessed it…you have to draw a bird. Then you share it! Perfect for Sunday Art!
For more info, see http://en.wikipedia.org/wiki/DABDay
This Sunday the theme for Sunday Art is Shapes. This Sunday is also Easter Sunday. See if you can combine this all some how! Have fun!
