“The calci worms are larger and fatter than the mealworms: I mix them in with the sunflower hearts and they seem most popular both on the bird tables and on the ground.”
“I wasn't sure if our garden birds would take to them, as they have been fed mealworms before, but I needn't have worried! After a day or two, the worms are now being hoovered up by several different species - starlings, blackbirds and robins - as soon as I put them out (mixed in with seeds).”
