The question of what bird does not tweet is a bit ambiguous, as there are many birds that do not make tweeting sounds. However, if we assume that the question is asking about a bird that is commonly associated with tweeting, the answer would be the common cuckoo (Cuculus canorus).
The common cuckoo is a bird that is found throughout Europe and Asia, as well as parts of Africa. It is known for its distinctive call, which is often described as a “cuckoo” sound. However, the sound that the cuckoo makes is not a tweet, but rather a series of two notes that are repeated over and over again.
The cuckoo’s call is actually a type of vocal mimicry, as the male cuckoo will often mimic the call of other birds in order to attract a mate. The male cuckoo has a unique ability to mimic the calls of many different species of birds, which allows it to fool females into thinking that it is a different type of bird.
Once the female cuckoo has been attracted to the male’s call, she will lay her eggs in the nests of other bird species. The female cuckoo will typically choose the nest of a bird species that is smaller than her own, as this makes it easier for her to lay her eggs without being detected. Once the cuckoo’s eggs hatch, the young cuckoo will push the other eggs out of the nest and demand all of the food and attention from the foster parents.
While the common cuckoo is known for its distinctive call, there are many other birds that do not make tweeting sounds. For example, the bald eagle (Haliaeetus leucocephalus) is a bird of prey that is found in North America, and it makes a variety of sounds, including screeches, whistles, and chirps, but it does not make tweeting sounds.
Similarly, the penguin is a bird that is found in the southern hemisphere, and it makes a variety of unique sounds, including braying, trumpeting, and growling, but it does not make tweeting sounds.
In conclusion, the bird that is commonly associated with tweeting is the common cuckoo, but it is important to note that there are many other birds that do not make tweeting sounds. The common cuckoo is known for its distinctive call, which is actually a type of vocal mimicry that allows the male cuckoo to attract a mate. While the cuckoo’s call is often imitated in cartoons and other media to represent tweeting, it is not actually a tweet, but rather a unique two-note call that is repeated over and over again.
