A bird feeder includes a feed container with a sidewall portion that diverges upwardly from a mouth. A framework nestably receives the container and has first and second support members extending around the container in parallel planes. The first and second support members are interconnected by rigid bars that may be curvilinear in shape. The container mouth attaches to a base that has a passageway with an outer opening that is thus placed in communication with the containers interior. A hanger assembly is used to suspend the feeder from a support. The base may have a plurality of passageways each with an outer opening that are spaced apart from one another. The rigid bars may be decorative, and decorative images may also be disposed on the framework. A method of feeding birds with this feeder is also disclosed.

The apparatus of claim 1, wherein said apparatus for decreasing drag force of a ship using the flexible air pipe is locally installed in a bow or stern of the ship to control local fluid flow around the ship. 4. The apparatus of claim 2, wherein said apparatus for decreasing drag force of a ship using the plates is locally installed in a bow or stern of the ship to control local fluid flow around the ship. 5. The apparatus of claim 1, wherein said pipe housing is installed in the interior of the hull of a ship. 6. The apparatus of claim 2, wherein said pipe housing is installed in the interior of the hull of a ship. 7. A method for decreasing drag force by controlling turbulent flow on a hull surface of a ship, comprising the steps of: sucking and ejecting fluid flowing along the hull surface of the ship to vary turbulent field of the fluid flow; and controlling an ejection angle with respect to the hull surface of the ship, the sucked fluid being ejected at the ejection angle, wherein friction resistance on the hull surface is decreased by performing the sucking and ejecting and controlling steps, wherein said ejection angle is in the range of about 60°＿120°, wherein the sucking and ejecting step includes: providing a container with a slit; sucking the fluid into the container through the slit; and ejecting the sucked fluid out of the container through the slit at the ejection angle. 8. An apparatus for decreasing drag force by controlling turbulent flow on a hull surface of a ship, the apparatus comprising: a pipe housing installed on the hull surface of the ship, the pipe housing including a plurality of slits through which fluid is sucked into or ejected out; first plates each disposed at one end of each slit; second plates each disposed at the other end of each slit; a first rod for connecting the first plates with each other; a second rod for connecting the second plates with each other; a motor for moving the first and second rods in opposite directions, respectively. 9. The apparatus of claim 8, wherein the apparatus for decreasing drag force is locally installed in a bow or stern of the ship to control local fluid flow around the ship. 10. The apparatus of claim 8, wherein the pipe housing is installed in the interior of a hull ship. wherein the boat cover includes stayput fasteners for securing the boat cover to the boat. 5. The combination according to claim 1 wherein the boat cover includes tie-down straps for securing the boat cover to a trailer when the boat is on a trailer. 6. The combination according to claim 1 wherein the boat cover includes at least one flap for covering the zipper means. port structure for supporting said tracks, comprising at least first, second and third track support surfaces at substantially right angles to each other, forming a channel in which said tracks are within the interior of said channel; a plurality of self-propelled containers having at least three surfaces for facing said first, second and third track support surfaces, each of said surfaces having track engagement means for selectively engaging said tracks on any of said first, second and/or third track support surfaces, said containers each further comprising container drive means for propelling said container along said tracks and container control means for controlling operation of said drive means, said control means being in operative communication with a central controller; a plurality of track switches to direct said container to switch between said tracks for changing the direction of travel of said container or for avoiding contact with a different of said containers, said switches being under the control of said central controller; and a central controller in operative communication with said switches and said drive means, said controller including signal processing means for receiving information corresponding to the location of said first and second locations, as well as the speed, location and direction of travel of each of said plurality of containers, and for providing instructions to said plurality of containers and switches to route said containers and to avoid undesirable contact between said containers. 2. A system as defined in claim 1 said plurality of tracks and track support structure comprises a branching network defined by of a plurality of regions. 3. A system as defined in claim 1, wherein said support structure comprises four support surfaces arranged in a substantially enclosed tube-like configuration, said plurality of self-propelled containers including track engagement means on at least four surfaces thereof for selectively engaging tracks on any of said four support surfaces. 4. A system as defined in claim 1, wherein said plurality of containers are modular and comprise individual containers for engagement with a lesser number of tracks and a greater number of tracks. 5. A system as defined in claim 1, wherein said first and second locations comprise stations for delivery and receipt of said containers. 6. A system as defined in claim 1, wherein said drive means of a said containers comprises an electric motor, driven by a power source selected from a battery within said car or an electrical current-carrying track associated with said tracks, said motor being operatively connected to at least one drive wheel. 7. A system as defined in claim 1, wherein said track engagement means comprises at least one slot recessed into a wall of said container, for engagement with a corresponding track. 8. A system as defined in claim 1 comprising a branching network of said track support structures and tracks wherein said channels comprise a plurality of interior cross-sectional areas within different regions of said network. 9. A system as defined in claim 1 wherein said switches are arranged to switch the track engagement of said containers on any of said support surfaces. 10. A system as defined in claim 1 for transporting said containers from point-to-point within said network, wherein said containers independently receive control information from said controller for uninterrupted movement from origin to final destination. 11. A system as defined in claim 8 wherein said containers are modular in size and independently controlled by said controller.
