Where are Pelecaniformes found?
GEOGRAPHIC RANGE. Since most of the birds in the Pelecaniformes order are seabirds, they can be found in oceans, at seashores, and on ocean islands all around the world. A few of the birds live inland near big lakes and rivers. Because they eat only water animals, none of them can live in dry areas.

How are tropic birds different from other pelecaniforms?
In particular, the tropic birds (Phaethontes) differ in many ways from the other members of the order Pelecaniformes and may well be wrongly placed in this order. They are united to the others primarily by the totipalmate condition, but the first toe in Phaethontes is distinctly more elevated on the tarsometatarsus than in the other groups.
What kind of noise does a pelecaniform make?
Most pelecaniforms are gregarious, gathering in colonies for breeding and roosting in large groups. Pelecaniforms are notably noisy when in large groups. Vocalizations are variable with species, and range from the sharp piercing whistle of the tropicbirds to the guttural grunting of cormorants.
