Definition of Pelicans and Storks

Pelicans:

Pelicans belong to the Pelecanidae family of water birds and can be distinguished by their large throat pouches and webbed toes, along with their distinct feeding behavior and distinctive appearance. Pelicans can be found all around the world in both coastal and aquatic habitats and are well known for diving from above into waterways with great grace in order to catch fish.

Their expandable pouches in their throats allow them to do just this while remaining graceful during flight. Pelicans play an integral part in ecosystems while their beauty makes them beloved animals in many cultures around the globe – pelicans are highly respected creatures!

Storks:

Storks, which belong to the Ciconiidae family of birds, are large wading birds with long legs adapted for wading in shallow waters. Storks possess distinctive appearance and nesting habits which set them apart. Storks can be found worldwide in wetlands, forests, grasslands and other environments.

Storks are generally carnivorous birds that feed on amphibians and insects – usually by stalking prey before probing it with their bills in water or land environments. Storks create large nests often constructed out of manmade or treetop structures. As monogamous birds, storks return year after year to their nesting spots for mating purposes and eventually return as adults each spring. Some species migrate long distances while in many cultures they are revered as graceful flyers.
