Reel Draggin' Tackle Humming Birds and Big Birds are our own design. Birds add action to your spread. They can be particualy effective on calm days. The 4.5 " Humming bird is a solid plastic mold, designed specificaly for spreader bar and daisy chain applications. Our 9" RDT Chick Birds are ideal birds for just about any rigging option you have. They have a single wire running the lenght of the bird. Looking for a bigger bird teaser? Our 13" Big Bird was designed for long rigger or way back down center use. It is very effective with a daisy chain behind it. Both the 9" and 13" birds are light weight teasers designed to generate maximum surface noise. These two birds have a single stainless steel wire that runs the lenght of the bird.
