[0002] Birds, as an important component of terrestrial wildlife and a vital part of biodiversity, can indicate changes in the environmental quality of natural ecosystems. Studying migratory bird patterns plays a crucial role in disease prevention and control. Bird banding is a fundamental method for studying avian conservation biology; however, currently, the selection of band sizes for birds often relies on personal experience or measurements using calipers. This method has limitations: firstly, measuring leg data using calipers requires binding the bird to ensure stable cooperation, a time-consuming process; secondly, relying on human experience can introduce errors, especially with closed leg bands. Choosing the wrong size band can lead to data loss, or worse, discomfort due to an undersized band, or even metatarsal necrosis, infection, or death due to an overly tight band. Utility Model Content

[0007] According to the bird leg banding matching device provided by this utility model, the model mark includes a number position and a letter position. The number position is the same as the integer position of the preset width dimension of the matching groove, and the letter position is the letter B, which represents 0.5 mm.
[0008] According to the bird leg banding matching device provided by this utility model, the matching groove is a rectangular groove, and the depth of the rectangular groove is greater than or equal to half of the preset width dimension of the corresponding matching groove.
[0009] According to the bird leg banding matching device provided by this utility model, the matching card is at least a rectangular card, a polygonal card, a circular card, or an elliptical card.

[0027] This invention provides a bird leg banding matching device, comprising a matching card with multiple matching grooves of different preset widths on its edge. Each matching groove has a corresponding model mark, which is identical to the model mark on a band of the corresponding size. In use, the bird's tarsometatarsus or tibia is first observed and its approximate diameter range is estimated. Then, several matching grooves within this diameter range are selected for trial matching. Finally, the model mark of the matching groove with the smallest preset width that allows the bird's tarsometatarsus or tibia to enter is read. The band with the same model mark is the most suitable for the bird. Compared to existing methods of dynamically measuring leg data using calipers, this bird leg banding matching device uses fixed-size matching grooves for trial matching, eliminating the need to bind the bird, greatly improving measurement efficiency. Furthermore, the fixed width of each test groove and the corresponding fixed band size eliminate errors caused by manual measurement, solving the problem of easily incorrect band size selection.
[0028] The following is combined Figure 1 and Figure 2 This invention describes a bird leg banding matching device.
[0029] An embodiment of this utility model provides a bird leg banding matching device, including a matching card 100. Multiple matching grooves 200 of different preset widths are provided on the edge of the matching card 100, and a corresponding model mark 300 is provided at the position corresponding to each matching groove 200. The model mark 300 on the matching card 100 is the same as the model mark of the corresponding size band.
[0030] During measurement, the diameter range of the bird's tarsometatarsus or tibia can be roughly estimated based on the bird species or through observation. Then, several matching grooves 200 with a preset width within that diameter range are selected for trial matching. Finally, the model mark 300 of the matching groove 200 with the smallest preset width that allows the bird's tarsometatarsus or tibia to enter is read. The band with the same model mark 300 is the band that best matches the current bird.
[0031] The bird leg banding matching device provided by this utility model uses multiple matching grooves 200 with different preset widths to match birds for banding. This solves the problems of easy error in banding size selection and long measurement time caused by the existing technology of matching bands by estimating based on experience and using dynamic measurement methods such as vernier calipers. Using the bird banding matching device provided by this application can greatly speed up the matching process and eliminate the problem of matching errors.
[0032] In some embodiments, the preset width of the matching groove 200 is between 3 mm and 25 mm, and the outer diameter of the tarsometatarsus or tibia of most common birds is within this size range, which can cover the tarsometatarsus or tibia sizes of at least 28 common birds.
[0033] For example, the matching grooves 200 can include 19, and the preset width dimensions of the 19 matching grooves 200 can be 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 8 mm, 8.5 mm, 9.5 mm, 11 mm, 13 mm, 14 mm, 15 mm, 16 mm, 18 mm, 19 mm, and 25 mm, respectively. Of course, more matching grooves 200 can be further subdivided, for example, including 3.1 mm, 3.6 mm, 4.2 mm, etc. The finer the dimensional precision, the higher the matching accuracy, but it will also take longer to try matching, resulting in an excessively long matching time.
[0034] In some embodiments, the model designation 300 may be in the form of numbers and letters, where the number part is the same as the integer part of the preset width dimension of the matching groove 200, and the letter part is the same as the decimal part of the preset width dimension.
[0035] For example, if the letter B represents 0.5 mm, then the model designation 300 corresponding to the matching groove 200 with a preset width of 6.5 mm is 6B. Or, if the letter A represents 0.2 mm, then 8A is the model designation 300 corresponding to the matching groove 200 with a preset width of 8.2 mm.
[0036] In some embodiments, the matching groove 200 can be a rectangular groove, and the depth of the rectangular groove must be greater than or equal to half of the preset width of the corresponding matching groove 200. This ensures that the widest part of the bird's leg bone enters the matching groove 200. If the depth of the rectangular groove is less than half of the preset width of the matching groove 200, the matched band size may be too small.
[0037] In some embodiments, the matching card 100 can be a rectangular card, a polygonal card, a circular card, or an oval card, etc.
[0038] In one specific embodiment, the matching card 100 is a rectangular card, and multiple matching grooves 200 are disposed on the four sides of the rectangular card. Of course, they can also be disposed on only one, two, or three sides of the rectangular card.
[0039] When the matching card 100 is a circular card, multiple matching grooves 200 can be evenly distributed on the outer periphery of the circular card.
[0040] In some embodiments, the dimensions of the plurality of matching grooves 200 may gradually increase along a certain direction, either clockwise or counterclockwise.
[0041] In some embodiments, at least the outer side of the matching card 100 is made of a flexible material, so as to avoid injuring birds during matching.
[0042] For example, the material of the matching card 100 can be a flexible material with support, such as rubber, or it can have a rigid support plate inside and a flexible outer film such as rubber on the outside.
[0043] Furthermore, the edges of the matching card 100 and the groove edges of the matching groove 200 can be chamfered to prevent birds from getting stuck or scratched during matching.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
