Final answer:
Birds do not use pheromones as part of their courtship advertisements, instead, they rely on vocalizations, visual displays, and other behaviors for mating communication.
Step-by-step explanation:
The animal that does NOT use pheromones as part of its courtship advertisements is birds. While dogs, bees, and snakes utilize pheromones for communication with potential mates among other functions, birds primarily rely on other modes of communication. A common example of bird communication is the release of chemical compounds to alert others of predators, but not typically for attracting mates. Instead, birds use a variety of other signals such as vocalizations, visual displays, and dancing to attract partners and communicate with each other. Pheromones play a crucial role in the communication systems of many animals, for instance, male snakes are able to detect the presence of a female ready for mating through pheromones that bind to receptors inside their vomeronasal organ, sending a cascade of signals that result in the recognition of potential mates.
