The £1m campaign, created by TBWA\Manchester, focuses on the food's nutrients and uses the strapline "bring more birds to your table".
Spots will air across ITV1, Channel 4, Channel 5, Nickelodeon, Disney XD, Sky1 and Sky Atlantic until 27 November.
Media planning and buying was handled by MEC.
Keith Nicholson, marketing director of Westland Horticulture, said: "The advert is really striking and it will certainly capture the imagination.
"The media campaign deployed around it will definitely help Peckish to gain a great share of voice and hopefully inspire a whole new set of bird feeders in the UK."
The campaign was directed by Chris Gaffey at The Mob Film Company, and created in association with visual effects company Jellyfish.
The spot's copywriter was Lisa Nichols; editor, Rob Featherstone; art director, Gary Fawcett; producer, Mark Collins; planner, Helen Davies; media planner, Alex Heywood.
Post-production work was completed by Envy Post.
In 2004, Westland Horticulture launched its biggest ever TV and press activity as part of a three-year £17.5m campaign.
