Our pigeons favorite treat is safflower seeds. This is a jar that I keep by the door to the back porch. All I have to do is shake it and they come right away.
I did this with caran d'ache (water soluble crayons) and house paints. Some of my first paintings were done with house paint. I often return to this medium, it's feels refreshingly uncomplicated. I keep the palette simple---red, yellow, blue and white.
