What does whistler mean?
Whistler most often names a person who produces a clear, high-pitched whistle. Depending on context, it can also denote a device that generates a whistle-like signal, a horse noted for jumping obstacles, or a naturally occurring radio phenomenon heard as a descending electronic tone. As a verb, to “whistler” means to make such a high-pitched sound, and in equestrian usage it can describe a horse clearing an obstacle. The word’s sound and meaning invite confusion with “whistle,” but the two are not interchangeable: the shorter word names the sound, act, or instrument, whereas “whistler” normally identifies the person or agent responsible for it. Common usage is informal and occasionally literary, while the radio sense is technical. The term is also evocative because lightning can excite the upper atmosphere to produce real, naturally generated radio “whistles.”

In technical writing, the word can denote a naturally occurring very-low-frequency radio signal associated with electrical activity in the upper atmosphere.
To make a high-pitched whistling sound; of a horse, to jump or clear an obstacle.

The verb is less common than the noun, and its equestrian sense is restricted to specialist usage.
The regular plural is used for multiple people, devices, signals, or horses.
"The street whistlers entertained the crowd with an improvised duet."
Lightning can make the upper atmosphere generate real radio “whistles” that sweep downward through the magnetosphere.

Where does whistler come from?
Whistler is formed from the English base whistle with the agent suffix -er. Whistle has Middle English roots and is generally treated as imitative of the sound produced through pursed lips; the related game term whist and its verb arose from the same whistling idea. The later specialized senses of whistler refer to devices, radio phenomena, and horses that clear obstacles, while its verb use developed from the idea of making the characteristic sound.
How whistler is actually used
The ordinary noun is informal and may sound playful or literary. The radio meaning is technical, referring to naturally generated very-low-frequency emissions, while the horse-related noun and verb belong chiefly to equestrian vocabulary.
