Step 3: Identify all the birds you see or hear within your planned time/location and use the best tool for sharing your bird sightings:

• If you are a beginning bird admirer and new to bird identification, try using the Merlin Bird ID app to tell us what birds you are seeing or hearing.
• If you have participated in the count before and want to record numbers of birds, try the eBird Mobile app or enter your bird list on the eBird website (desktop/laptop).
