 Honey is made by bees from the nectar of flowers, but it is not good to use in feeders because when it is diluted with water, microorganisms easily grow in it, causing it to spoil rapidly.Red food dye was once thought to be a favorable ingredient for homemade solutions, but it is unnecessary, and there is no point in adding it to the nectar.Some people speculate red dye could be bad for the birds, although this claim has not received scientific attention.
