Yes, you can select your state and the time of year to help the app identify sounds using a list of likely species. From the main menu select “Species List” and at the top of that screen you should see selectors for location and date. Simply select your state or province, and select the appropriate half-month period (or set the date to “Auto” and let your device adjust to the current date). This limits the species under consideration to the list for that area and time of year.
