Hello everyone,
When it comes to using a protopatagial tag in birds, I wonder if it is essential to tag both wings to retain birds‘ "balance", or if one tag is alright. While browsing papers, I could come across both alternatives, individuals carrying only one protopatagial tag or birds with both wings marked. Thank you for sharing your experience and clarification.
Protopatagial tags are small, lightweight tags that are attached to the primary feathers (also known as flight feathers) of birds' wings. These tags are used for identification and tracking purposes, and are commonly used in research studies on bird migration and behavior.
It is generally recommended to tag both wings of a bird with protopatagial tags in order to maintain the bird's balance and ensure that it can fly properly. This is because the primary feathers on both wings work together to provide lift and propulsion during flight, and attaching a tag to only one wing could potentially disrupt this balance.
However, it is possible that some birds may be able to fly normally with a single protopatagial tag, depending on factors such as the size and weight of the tag, the species of bird, and the individual bird's body size and wing shape. Some studies have found that attaching a protopatagial tag to just one wing has minimal or no impact on a bird's flight ability, while other studies have reported that attaching a tag to one wing can cause a slight reduction in flight performance.
Ultimately, the decision to tag one or both wings with protopatagial tags will depend on the specific research goals of the study, as well as the potential impacts on the birds' behavior and welfare. It is important to carefully consider these factors and follow any guidelines or regulations that may be in place for tagging birds.
