A collapsible bird feeder having a tubular lower chamber with feed ports near the bottom of the lower chamber and side walls extending from the top of the lower chamber to the bottom of the lower chamber is disclosed. A lip extends inwardly from the side walls near the top of the lower chamber. A tubular upper chamber has feed ports near the lower end of the upper chamber and side walls extending from the top of the upper chamber to the bottom of the upper chamber. A lip extends outwardly from the side walls of the upper chamber near the bottom of the upper chamber. A fill tube extends from the top of the upper chamber through the bottom of the upper chamber to allow material to pass from near the top of the upper chamber into the lower chamber. The lower chamber has an inner perimeter and the upper chamber has an outer perimeter. The outer perimeter is of similar cross sectional shape and slightly smaller than the inner perimeter to allow the upper chamber so that the upper chamber may slide within the lower chamber.

We claim: 1. A collapsible, multi-chamber bird feeder, comprising: a first chamber enclosing a first volume, the first chamber having at least one feed port in fluid communication with the first volume; a second chamber enclosing a second volume, the second chamber having at least one feed port in fluid communication with the second volume, the first chamber being extensibly carried in the second chamber; and a fill tube located within the first volume, the fill tube extending from an outer portion of the first volume and being in fluid communication with the second volume for allowing material to pass through the fill tube and into the second volume; wherein the first chamber is movable between a retracted position, in which at least a portion of the first chamber is located within the second chamber, and an extended position, in which the first chamber substantially extends from the second chamber; and wherein the first and second volumes are separated to prevent fluid communication between the volumes. 2. The feeder according to claim 1, further comprising: retention means for retaining the first and second chambers together by preventing movement of the first chamber beyond the extended position. 3. The feeder according to claim 2, wherein the retention means comprises a lip on each of the chambers, the lips being configured to engage each other when the first chamber is moved to the extended position. 4. The feeder according to claim 1, wherein the first and second chambers have a circular cross-sectional shape. 5. The feeder according to claim 1, further comprising: a handle attached to one of the first and second chambers. 6. The feeder according to claim 1, further comprising: at least one perch cage attached to an exterior of one of the first and second chambers. 7. The feeder according to claim 1, further comprising: a removable lid configured for covering the outer portion of the first volume. 8. A collapsible, multi-chamber bird feeder, comprising: a first chamber enclosing a first volume, the first chamber having at least one feed port in fluid communication with the first volume; a second chamber enclosing a second volume, the second chamber having at least one feed port in fluid communication with the second volume, the first chamber being extensibly carried in the second chamber; a first perch cage attached to the first chamber and spaced from a perimeter of the first chamber; and a second perch cage attached to the second chamber and spaced from a perimeter of the second chamber; wherein the first chamber is movable between a retracted position, in which at least a portion of the first chamber is located within the second chamber, and an extended position, in which the first chamber substantially extends from the second chamber; and wherein the first and second volumes are separated to prevent fluid communication between the volumes. 9. A multi-chamber, collapsible feeder, comprising: a lower chamber having a feed port and a lip at an upper end of the lower chamber; an upper chamber slidingly engaged with the lower chamber, the upper chamber having a feed port and a lip at the bottom of the upper chamber, the upper chamber also having a fill tube extending through a bottom of the upper chamber for communicating the lower chamber with the interior of the fill tube; a first perch cage attached to the upper chamber and spaced from a perimeter of the upper chamber; and a second perch cage attached to the lower chamber and spaced from a perimeter of the lower chamber; wherein the upper and lower chambers are separated to Prevent fluid communication therebetween; and wherein the lips cooperate to prevent the upper chamber from separating from the lower chamber. 10. The feeder according to claim 9, wherein the upper and lower chambers have a circular cross-sectional shape. 11. The feeder according to claim 9, further comprising: a handle attached to the upper chamber. 12. The feeder according to claim 9, further comprising: a removable lid configured for covering an end of the upper chamber located opposite the lower chamber. 13. A collapsible bird feeder, comprising: a tubular lower chamber with feed ports near a bottom of the lower chamber; and a tubular upper chamber with feed ports near a lower end of the upper chamber, the upper chamber being slidingly carried within the lower chamber and movable between a retracted position and an extended position; and a fill tube extending from the top of the upper chamber through the bottom of the upper chamber for allowing material to pass from the top of the upper chamber into the lower chamber; wherein the lower chamber has an inner perimeter and the upper chamber has an outer perimeter, the outer perimeter being of similar cross-sectional shape and slightly smaller than the inner perimeter to allow the lower chamber to slidingly carry the upper chamber within the lower chamber. 14. The feeder according to claim 13, wherein the upper and lower chambers have a circular cross-sectional shape. 15. The feeder according to claim 13, further comprising: a handle attached to the upper chamber. 16. The feeder according to claim 13, further comprising: a first perch cage attached to the upper chamber and spaced from the outer perimeter of the upper chamber; and a second perch cage attached to the lower chamber and spaced from an outer perimeter of the lower chamber. 17. The feeder according to claim 13, further comprising: a removable lid configured for covering the top of the upper chamber.
