Westland nutritional technologist Lorron Bright said: "This unique blend of seeds give a unique texture proven through field trials to attract a greater variety of birds, including smaller, more colourful species such as blue tits and songbirds.
"Also, our Peckish Complete Energy Balls are the only energy balls to be enriched with the extra energy of a 12 seed blend, plus Calvita, a supplement unique to Peckish, which enhances plumage colour and promotes healthier brighter birds."
Westland marketing manager Wendy French said: "The Peckish brand has a fun and vibrant personality, making it ideal to entice more people into feeding the birds.
"This brand new look and product offering will really stand out on shelf, making it even easier for customers to spot Peckish products and more importantly, put them in their basket."
