The family Pelecanidae consists of large water birds known as pelicans, characterized by their distinctive long beaks and expandable throat pouches used for catching and holding fish. These birds are found worldwide, primarily in warm regions near coasts, lakes, and rivers. Pelicans are highly social and often nest in colonies, feeding mainly on fish which they scoop up with their pouches, sometimes working cooperatively to herd schools of fish. They have strong, broad wings that enable efficient soaring and gliding over water. Members of Pelecanidae exhibit strong parental care, with both parents involved in incubating eggs and feeding chicks. Their striking appearance, specialized feeding adaptations, and social behavior make them a unique and easily recognizable bird family.
