A. 1. Check the app settings for an option related to recording behavior, such as 'append' or 'overwrite'. 2. If available, select the 'append' option to ensure new recordings are added to existing tracks instead of overwriting them. 3. If no such option exists, consider manually saving each recording with a unique name before starting a new one.

B. 1. Create a habit of stopping the recording after each segment and saving it immediately. 2. Use a separate audio recording app that allows for multiple tracks if BirdNET does not support this feature.
