    Use our quick, clickable guide for identifying backyard birds by the sounds they make! Chose any of these popular species to hear its typical bird sounds, from vocalizations of parrots to the chirping of songbirds. As you?re gardening in your backyard or wandering in the woods, you might be able to use our guide to identify a few distinctive bird calls. Identification of songbird sounds has a rich history; in the past, it was fairly complicated and frequently required mnemonics. For instance, the blue jay is recognized for singing ?queedle, queedle, queedle,? and the mourning dove sound can be written as ?hooo-ah hoo-hoo-hoo.? The northern flicker sounds like ?squeechu-squeechu-squeechu,? which might be easy to confuse with ?queedle? unless you?ve heard it in the wild yourself! It?s also helpful to consider where you are when you?re trying to identify birds; check out the maps to see if a particular bird is actually found in your area.
    Today, identification is easier when you can listen to birds singing in short sound clips. Click a bird to hear birds tweeting their ?language.? Note that some of these birds have different sounds based on the situation, too. For instance, many songbirds have an ?alarm? noise along with its normal tittering that can sound a little different. Tweets can also have a different tune than full calls. But this list of 50 birds should certainly be able to get you started!
    There are plenty more migratory bird sounds to discover, too. If you really want to become a pro bird-sound-identifier, you'll want to learn more about the pitch, rhythm, and repetition of birdsong!
