1. A top-fill hummingbird feeder comprising:

a nectar container having a lower end with a bottom opening and an upper end with a top opening;

a feeding basin removably coupled to the lower end of the nectar container and in liquid flow communication with said bottom opening;

a cap including a downwardly projecting annular rim on a bottom surface thereof; and

a sealing member separate from the cap and including an annular ring that encircles the cap rim with an inner edge of said sealing member being in abutment with an outer surface of said annular rim when the sealing member is mounted to the cap, the sealing member configured for an interference press fit with the top opening of the nectar container, the sealing member including at least one void to allow air passage so that liquid is able to flow from the nectar container into the feeding basin when the feeder is in use.

2. The top-fill hummingbird feeder as set forth in claim 1 , wherein an outer perimeter edge of said ring includes a plurality of fins vertically spaced from one another, each fin having at least one void therein.

3. The top-fill hummingbird feeder as set forth in claim 2 , wherein at least some of the voids in adjacent fins are vertically aligned with one another.

4. The top-fill hummingbird feeder as set forth in claim 3 , wherein the voids are formed as notches having a limited radial extent.

5. A top-fill hummingbird feeder comprising:

a nectar container having a lower end with a bottom opening and an upper end with a top opening;

a feeding basin removably coupled the lower end of the nectar container and in liquid flow communication with said bottom opening; and

a cap assembly for closing the top opening of the nectar container, the cap assembly including a cap and a sealing member configured for an interference press fit within the top opening of the nectar container, the sealing member including a plurality of fins each having at least one void therein to allow air passage through said voids so that liquid is able to flow from the nectar container into the feeding basin when the feeder is in use.

6. The top-fill hummingbird feeder as set forth in claim 5 , wherein the cap includes a downwardly projecting annular rim on a bottom surface thereof, said sealing member including an annular ring that encircles the cap rim with an inner edge of said sealing member being in abutment with an outer surface of said annular rim when the sealing member is mounted to the cap.

7. The top-fill hummingbird feeder as set forth in claim 5 , wherein at least some of the voids in adjacent fins are vertically aligned with one another.

8. The top-fill hummingbird feeder as set forth in claim 7 , wherein the voids are formed as notches having a limited radial extent.

9. A top-fill hummingbird feeder comprising:

a nectar container having a lower end with a bottom opening and an upper end with a top opening;

a cap including a downwardly projecting annular rim on a bottom surface thereof; and

a sealing member including an annular ring that encircles the cap rim with an inner edge of said sealing member being in abutment with an outer surface of said annular rim when the sealing member is mounted to the cap, the sealing member configured for an interference press fit with the top opening of the nectar container, the sealing member including at least one void to allow air passage so that liquid is able to flow from the nectar container into a feeding basin of the feeder when the feeder is in use.

10. The top-fill hummingbird feeder as set forth in claim 9 , wherein an outer perimeter edge of said ring includes a plurality of fins vertically spaced from one another, each fin having at least one void therein.

11. The top-fill hummingbird feeder as set forth in claim 10 , wherein at least some of the voids in adjacent fins are vertically aligned with one another.

12. The top-fill hummingbird feeder as set forth in claim 11 , wherein the voids are formed as notches having a limited radial extent.
