## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims benefit of priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 61/619,414, entitled “Goldfinch Feeder” and filed on Apr. 2, 2012, specifically incorporated by reference herein for all that it discloses or teaches.


BACKGROUND
Many bird feeders offer a number of fixed perches with corresponding feeding openings positioned relative to each of the perches. However, such bird feeders fail to consider that birds, particularly different species of birds, feed in a variety of positions. For example, the goldfinch often feeds upside down, while the house finch is unable to feed upside down. Accordingly, if an owner desires to attract goldfinches and exclude house finches and other birds, the owner generally must purchase a bird feeder having feeding openings positioned below each perch. However, if the owner changes his mind and wishes to attract house finches and other birds in addition to goldfinches, the owner must generally purchase another bird feeder entirely with feeding openings placed above each perch. Accordingly, many bird feeders fail to take into consideration the variety of positions in which different birds, particularly the goldfinch and house finch, feed.
It is with these observations in mind, among others, that various aspects of the present disclosure were conceived and developed.

DETAILED DESCRIPTION
Aspects of the present disclosure involve apparatuses and methods for providing different perch positions for feeding birds. In one particular aspect, a bird feeder with a rotating perch is provided. The bird feeder includes a reservoir configured to hold bird food. The reservoir has a wall and at least one opening in the wall providing access to the bird food. A feeding station is configured to be mounted on the wall relative to the opening. The feeding station includes a port through which a bird may access the bird food in the reservoir and a perch from which the bird may access the port. The perch is connected to the port such that the perch may be rotated to a plurality of positions relative to the port. The different positions allow birds that feed from different positions to access the bird food and further allow the owner to choose what birds to attract.
As can be understood from FIG. 1, which shows a perspective view of an example bird feeder 100, a reservoir 102 is configured to hold bird food, which may be a variety of different bird seeds of different sizes. In one implementation, the reservoir 102 includes a tube 104 and a mouth 106. The tube 104 has a generally cylindrical shape and the mouth 106 is tapered to accept bird food with minimal spillage. However, other shapes of the tube 104 and the mouth 106 are contemplated. The tube 104 includes a wall 108 having at least one opening providing access to the bird food. The bird feeder 100 includes a feeding station 110 configured to be mounted on the wall 108 relative to the opening. The feeding station 110 includes a port 112 through which a bird may access the bird food in the reservoir 102 and a perch 116 from which the bird may access the port 112. The perch 116 is connected to the port 112 such that the perch 116 may be rotated to a plurality of positions relative to the port 112. In some implementations, the feeding station 110 further includes a port plug 114. The port 112 is configured to receive the port plug 114 to mount the perch 116 on the bird feeder 100 such that it may be rotated to various positions. The bird feeder may include any number of feeding stations, including the feeding station 110. For example, as shown in FIG. 1, the bird feeder 100 may include four feeding stations to accommodate more birds.
The mouth 106 is configured to receive a lid assembly 120 to close or occlude the reservoir 102. In one implementation, the lid assembly 120 includes a lid 122 which extends past the edge of the mouth 106. The lid 122 is held to the mouth 106 by a cable 124, which attached to the reservoir 102 and passes through the lid 122 at a knob 126 that is located at the substantial center of the lid 122. The cable 124 extends upwardly to attach to an item, including, without limitation, a tree limb or a hook.
FIG. 2 illustrates another perspective view of the bird feeder 100, which includes a second feeding station 202 mounted on the wall 108 generally opposite the feeding station 110. The second feeding station 202 includes a port 204 and a perch 206, as described herein. As can be understood from FIG. 2, the perches 116 and 206 may be rotated to a plurality of positions relative to the ports 112 and 204, respectively. For example, the perch 116 is positioned near the top of the port 112, and the perch 206 is positioned near the bottom of the port 204. However, the ports 112 and 204 are stationary, and the position of the ports 112 and 204 does not change as the perches 116 and 206 are rotated.
If an owner desires to attract goldfinches and exclude house finches and other birds, a perch of each feeding station of the bird feeder 100 are rotated to the position of the perch 116, as shown in FIG. 2. Specifically, each of the perches is rotated to a portion near the top of the ports. However, if the owner desires to attract house finches and other birds, the perches may be rotated to the position of the perch 206. The owner may also position the perches such that a first portion of the perches attract goldfinches and exclude other birds, including house finches, and a second portion of the perches attract house finches and other birds in addition to gold finches.
As shown in FIG. 3, the feeding station 110 is mounted on the wall 108. In one implementation, the feeding station 110 includes the port 112 and the perch 116, as described herein. In another implementation, the feeding station further includes the port plug 114. The perch 116 includes a surface 302 and a projecting portion 304 that extends from the surface 302. The port 112 is configured to attach the perch 116 to the wall 108 relative to an opening through which bird food may be accessed. In one implementation, the port 112 is configured to receive the port plug 114. As described with respect to FIG. 7, the perch 116 may be disposed between the port 112 and the port plug 114, thereby attaching the perch 116 to the wall 108. Once the perch 116 is attached to the wall 108, the projecting portion 304 extends outwardly from the wall 108.
In one implementation, the port plug 114 includes at least one access opening 306 sized to permit limited access to bird food held in the reservoir 102. For example, the bird food held in the reservoir 102 may be thistle seed, so the access opening 306 may be sized to permit limited access to thistle seed. In one implementation, the access opening 306 is approximately 9.6 mm tall and approximately 2.3 mm wide. However, other dimensions of the access opening 306 are contemplated depending on the size of the bird food held in the reservoir 102. Further, the perch 116 is attached to the port 112, such that as the perch 116 is rotated relative to the port 112. In one implementation, the projecting portion 304 is located at a constant distance relative to the access opening 306. For example, the projecting portion 304 may be consistently located approximately 34 mm away from the access opening 306.
As can be understood from FIG. 4, which is a cross sectional view of the bird feeder 100, the reservoir 102 may include one or more receiving portions for collecting bird food in the reservoir 102 and allocating the bird food to the one or more feeding stations. For example, a receiving portion 402 includes one or more angled surfaces to direct bird food at the feeding station 110. In some implementations, the receiving portions are configured to allocate bird food deposited in the reservoir 102 evenly to each of the feeding stations included in the bird feeder 100.
FIGS. 5 and 6 show a top cross sectional view 500 and a side cross sectional view 600, respectively, of a feeding station on the bird feeder 100. As described herein, each feeding station is mounted on the wall 108 relative to an opening 502 through which the interior of the reservoir 102 may be accessed. The port 112 is mounted on the wall 108 such that the opening 502 is not obstructed.
In one implementation, the perch 116 is connected to the port 112 using the port plug 114. Specifically, the port plug 114 snaps into the port 112, thereby piercing the wall 108 and retaining the perch 116. The surface 302 and the projecting portion 304 may then be rotated about an axis line 504 which lies at the approximate center of the port plug 114, near the access opening 306. As described with respect to FIGS. 7A-C, in one implementation, the port 112 and the port plug 114 remain stationary as the perch 116 is rotated. Further, as described with respect to FIG. 4, the reservoir 102 may include a receiving portion 506 for collecting and allocating bird food to the access opening 306. As shown in FIGS. 5 and 6, the receiving portion 506 may be a substantially thin wall having one or more surfaces for angling bird food at the access opening 306.
FIGS. 7A-C illustrate three perspective views of the feeding station 110 showing the perch 116 rotated to various positions. FIG. 7A shows the perch 116 rotated such that the surface 302 and the projecting portion 304 are positioned near the bottom of the port 112 below the access opening 306 on the port plug 114. The position shown in the view 700 may be used to attract house finches, other birds, and the goldfinch. FIG. 7B shows the perch 116 as the perch 116 is rotated counterclockwise towards the top of the port 112. During the rotation, the surface 302 and the projecting portion 304 are positioned at an angle relative to the access opening 306 on the port plug 114. Finally, FIG. 7C shows the perch 116 rotated such that the surface 302 and the projecting portion 304 are positioned near the top of the port 112 above the access opening 306 on the port plug 114. The position shown in the view 704 may be used to attract goldfinches and exclude house finches and other birds. As can be understood from FIGS. 7A-7C, in one implementation, as the perch 116 is rotated, the port 112, the port plug 114, and the access opening 306 remain stationary and are generally not affected by the rotation of the perch 116.
FIG. 7D illustrates an exploded view of the feeding station 110, which includes the port 112, the perch 116, and the port plug 114. In one implementation, the port 112 includes a surface 702 and a protruding portion 704 extending from the surface 702. The protruding portion 704 defines an opening 706. The surface 702 is shaped to minor the shape of the wall 108 such that the surface 702 fits snugly against the wall 108 once mounted. The protruding portion 704 has a generally circular shape. It will be understood by those of ordinary skill in the art that the protruding portion 704 may have a variety of shapes, including, but not limited to, rectangular, elliptical, triangular, and polygonal, and the surface 702 may have a variety of shapes, including shapes that do not minor the shape of the wall 108.
In one implementation, the perch 116 includes a ring 708 defining an opening 710. The ring 708 is sized relative to the protruding portion 704. For example, the ring 708 may be the same size as the protruding portion 704 such that when the protruding portion 704 is connected to the ring 708, the openings 706 and 710 create substantially one opening. However, in other implementations, the ring 708 is larger or smaller in size compared to the protruding portion 704. In one implementation, the protruding portion 704 is configured to receive the port plug 114 such that the perch 116 is disposed between the port 112 and the port plug 114. The general center of the openings 706 and 710 is positioned along the axis 504, which corresponds to the access opening 306 on the port plug 114. The access opening 306 provides the bird access to the bird food in the reservoir 102 via the openings 706 and 710.
FIGS. 8A and 8B illustrate a side view and a front view, respectively of the feeding station 110. In one implementation, the feeding station 110 includes the port 112 and the perch 116 configured to be mounted on the wall 108 of the reservoir 102 relative to an opening in the wall 108 that permits a bird to access bird food held in the reservoir 102. The perch includes a surface 302 from which a projecting portion 304 extends. The port plug 114 attaches the perch 116 to the port 112 such that the projecting portion 304 may be rotated to various positions relative to the access opening 306, as described herein.
As shown in FIG. 9, which is a side cross sectional view, the feeding station 110 is mounted on the wall 108 relative to an opening 502 through which the interior of the reservoir 102 may be accessed. The port 112 is mounted on the wall 108 such that the opening 502 is not obstructed. In one implementation, the perch 116 is connected to the port 112 using the port plug 114. Specifically, the port 112 includes a substantially flat portion 902 configured to engage a channel 904 of the flat portion 902. As described with respect to FIGS. 10-12, a barbed portion 906 is disposed between a portion of the port 112 and a portion of the port plug 114 such that the perch 116 is rotationally mounted to the wall 108. The surface 302 and the projecting portion 304 may then be rotated relative to the access opening 306. As described with respect to FIG. 7, in one implementation, the port 112 and the port plug 114 remain in the same position as the perch 116 is rotated. Further as described with respect to FIGS. 4 and 5, the reservoir 102 may include a receiving portion 506 for collecting and allocating bird food to the access opening 306.
FIGS. 10-12 illustrate back perspective views of various components of the feeder 110. In FIG. 10, the port 112 is shown, which includes the protruding portion 704 extending from the surface 702 to define the opening 706. In one implementation, the protruding portion 704 further includes the substantially flat portions 902 configured to engage the port plug 114. In one implementation, the surface 702 has a lip 1002, a first mounting portion 1004, and a second mounting portion 1106 each configured to engage a portion of the wall 108. For example, the lip 1002 extends from the surface 702 to provide a snug fit against the wall 108 along the length of the lip 1002. Further, the mounting portions 1004 and 1006 are configured to engage the reservoir 102 through an opening in the wall 108.
As can be understood from FIGS. 11 and 12, the port 112 may be configured to engage the port plug 114. In one implementation, the port plug 114 includes a tube 1104 and a lip 1102. The tube 1104 is inserted into the opening 706 such that the channels 904 to engage the flat portions 902 of the port 112. The port plug 114 may be inserted into the opening 706 until the barbed portion 906 of the perch 116 is engaged by both the lip 1104 and the port 112, thereby rotationally attaching the perch 116 to the port 112.
