We like to think that owls only hoot, but these sound a lot like human whistles and are easy to copy.
Marmots. Most marmots—found in mountainous areas in North America, Asia, and Europe—are social, using loud whistles to communicate with each other, earning many species the nickname “whistle pig.”
Carolina Wren. What is this? The Carolina Wren is a tiny bird with a loud, distinctive song that includes several trills and warbles. But if you listen closely, you'll also hear some notes that sound suspiciously like they were produced by a human whistle.
Songs. White-throated Sparrows sing a pretty, thin whistle that sounds like Oh-sweet-canada-canada or Old-Sam-Peabody-Peabody. The whistles are even but typically move slightly up or down in pitch by the second or third note.
Hill mynahs (tropical members of the starling family of birds) are renowned for their ability to mimic the human voice. It has been claimed that the hill mynah is the best talking bird and the best mimic in the world.

Male lyrebirds use their mimicking talents mainly for courtship, according to the National Audubon Society. During their breeding season, from June to August, male lyrebirds can be heard singing for up to 4 hours a day.

Whistling at night has long been considered a bad omen, but there are actually a few different interpretations of what it means.

The hoots have a deep, pure tone, with females' voices higher than males. To stay in contact, mated pairs also emit a hollow whistling sound that rises in pitch at the end.
The Wood Thrush's easily recognized, flute-like ee-oh-lay is actually only the middle phrase of a three-part song. It learns the phrase from other Wood Thrushes and sings several variants with 2 to 10 loud, clear notes.
Great horned owls make a meowing sound that can be described as cat-like. Here is a video with some of the distinctive sounds of a Great horned owl. Some birders have also reported that they have heard starlings making cat sounds.

In terms of vocal mimicry, they can imitate almost any whistle. A bottlenose dolphin taught to associate a particular whistle for "sargassum" even recently made that whistle after encountering some of the seaweed as it swam in the wild.
All animals with flapping wings make these sounds, but the hummingbird makes perhaps the most delightful sound of all: their namesake hum. Yet, how hummingbirds hum is poorly understood.
Air enters the whistle at one end. As the air reaches the other, closed end, all the air molecules "pile up" on top of each other and cause a high-pressure region. The air escapes out the little hole in the end, making the noise you hear. The frequency of the sound is dependent on the length of the whistle.
Improperly installed windows, worn weather stripping, changes in temperature and the simple passage of time can all cause an unwanted whistling inside the house.
