Note: Please take the following apps with several grains of salt; they utilize AI technology by comparing your photo/audio to others. While some of them are quite impressive, no app is perfect quite yet. Please use your own identification skills and other resources in addition to the following apps before making a definitive identification.
Google Lens - Photo ID (and a plethora of non-bird-related things)
Merlin Bird ID - Photo ID + Sound ID
BirdNET - Sound ID
