e and beak shape of birds have also been shown to play a role in the sounds they produce. A bird with a larger body will produce sounds with longer wavelengths; a bird whose beak gapes widely will produce a sound of higher frequency. In closed habitats like the forest or the woods, where sound can be lost to the surroundings, it is advantageous to produce sounds of lower frequency than those produced by birds from open habitats such as the savannah or grasslands (García 2018). Thus, the habitat of a songbird may indirectly affect its body shape. As birds have incredible control over the sounds they can produce, this skill is used primarily in mating rituals. Although both male and female birds have the mechanisms to produce and perceive song, male birds are the primary performers of song as part of their attempt to attract a mate. In order to attract a mate, males must use increasingly complex songs; otherwise habituation will occur in the female birds. Habituation refers to a female bird becoming “used” to a sound, so that it no longer captures her attention. Song learning birds, who are able to develop and produce new sound patterns within their lifetime, have been shown to mimic the calls of other birds, perhaps in order to increase the complexity of their repertoire and appear extra impressive. However, this behavior is somewhat paradoxical. Female birds must be able to distinguish calls made by their same species, or conspecific songs, in order to mate with those individuals, and genetically prefer conspecific songs (Miyamoto 2006). The perception of song by other birds plays a crucial role in bird evolution; those males whose songs are successful will mate, reproduce, and pass down their superior song-making abilities. While the noises produced by dolphins are not technically considered song, they provide a fascinating contrast to the form of vocal communication used by birds. Rather than creating sounds via a syrinx, the sound organ of birds, dolphins vocalize by pushing air through their nasal sacs. Within the nasal region, dolphins have two sets of phonic lips, structures that cause the surrounding tissue to vibrate as the air passes through. However, because studying the anatomy of dolphins as they make noises is difficult, science is not certain about the exact nature of these structures (Dolphin Research Center). Dolphins use their sounds not for mating, as birds do, but in order to communicate. They have been observed to chatter extensively with each other and seem to have their own names- a unique series of clicks and squeaks created by themselves as young dolphins- which they use to signal each other. Their communication capabilities are complex, and many dolphins have been trained to perform tricks that can provide insight into the extent of their capabilities. For example, show dolphins can repeat a series of commands at the signal of a trainer, including a signal to “innovate,>GET ANSWER
