With about three species recognized, skimmers are widely known members of the family Laridae. The tern-like seabirds included in the biologically classified genus Rynchops are the black skimmer of North America, African skimmer, and Indian skimmer.
All three members are known distinctly for their peculiar anatomical designs, which include lower elongated mandibles in comparison to their upper beaks.
A combination of black, white, gray, and red shades is known to adorn the bodies of skimmers. Skimmers are migratory birds and show varying locomotive patterns encompassing their winter, summer, and breeding seasons.

Skimmer Interesting Facts
What type of animal is a skimmer?
A skimmer is a biologically defined group of seabirds belonging to the Laridae family. There are three species of these avians with anatomically uneven beaks, that is, black skimmer (Rynchops niger), African skimmer (Rynchops flavirostris), and Indian skimmer (Rynchops albicollis), which are classified under the genus Rynchops.
What class of animal does a skimmer belong to?
Skimmers are the classified members of class Aves; that is, the biological classification of organisms characterized by the presence of forelimbs modified into wings, and the body is covered with feathers.
How many skimmers are there in the world?
There are no exact details about the skimmer’s global population for the avians belonging to the skimmer realm. The population of black skimmer species is quite stable as they are classified as the Least Concern on the conservation list.
However, their relatives, the African and Indian skimmer, face dire population threats. As of now, the Indian skimmer is recognized as an Endangered species, and African members are categorized as Near Threatened.
Where does a skimmer live?
Skimmers are a category of seabirds and, therefore can be typically spotted along the shores and water bodies. Black skimmers avians of the Rynchops genus are distributed over a wide range of surface habitats.
They are widely distributed along the terrains of North America and South America. Additionally, following their migratory patterns, the dwellers of the north are known to inhabit the warm water of the Caribbean and Pacific coasts, whereas the southern members span as far as Costa Rica along with the north ranges.
What is a skimmer's habitat?
The black skimmer bird's habitat is along the aquatics biomes and wetlands such as estuaries, rivers or streams, coastal marshes, lagoons, and brackish water bodies. As in the case of terrestrial inhabitation, these avians can be located along with the salt marsh mats, beaches, pools, dredge spoil, mudflats, and coastal marshes.
These regions make skimming through water possible for the black skimmer.
Who do skimmers live with?
The black skimmer is a social avian and is known to flock together with other members of their species. Besides forming pairs with their partners, small to large colonies comprising as many as 50-60 members are observed.
How long does a skimmer live?
The average lifespan of skimmers forming the biological genera Rynchops and Lardiae family is about 20-25 years.

The black skimmer bird nests on sand or salt marshes. They are monogamous; that is, these birds mate with only one partner throughout the breeding season and in fact, are quite aggressively territorial when guarding their mates.
In order to further woo their partners for copulation, the male presents the female member with captured fish. The paired partner accepts and clenches the fishes in her beak, following which the male mounts the female for insemination.
These avians differ from their relatives of the terns’ clan, as in the case of terns, the female part generally swallows the offered feed before copulation, whereas in the case of Rynchops niger, feeding generally follows after the copulation. The black skimmer is to behold annual breeding procedures, usually during the warm summer months.
Following insemination and fertilization, the females lay about four or five eggs over a span of about eight days. The incubation period of black skimmer bird eggs ranges between 21-26 days.
What is their conservation status?
According to the IUCN’s (International Union for Conservation of Nature) Red List, black skimmers have been categorized under the conservation status of Least Concern. However, amongst their relatives, the Indian skimmer is recognized as Endangered species, and African members are categorized as Near Threatened.
Skimmer Fun Facts
What do skimmers look like?
Besides the uneven and distinguishing designs of the beaks or bill in the skimmer (which contributes to their nickname scissor bill), the black skimmer avian category (which can be called the black and white skimmer bird) is further bestowed with a distinctive anatomical design of slit-shaped large pupil.

The tails of black skimmers are short, and grey patterned with white tips or spots. The Rynchops niger possesses slender, red-shaded legs.
The shading of the underwing ranges from gray to white shades, while the forewings are black with white edges. Nicknamed as scissorbills, the lower mandible part of the bill of the members of black skimmers species are comparatively longer than their upper proportions.

They survive through skimming. The skimmer birds feed through skimming the water by dipping their lower part of the bill in water to catch fish. This way they can hunt even at night.
The skimmer's adaptations
A major adaptation observed in skimmer birds is the rightful selection of breeding grounds to keep in order with the climatic as well as human threats. Besides, the hunting skills in water (skimming) aided by anatomical structure also facilitates the survival of these avians.
What kinds of skimmers are there?
The three species of skimmer that are well known are black skimmer (Rynchops niger), African skimmer birds (Rynchops flavirostris), and Indian skimmer bird (Rynchops albicollis), which exhibit the distinctive uneven anatomical designs of their beaks. The lower mandible part of the bill in these avians is comparatively elongated than the upper parts.
This feature has led to the nickname scissorbills.
Also, a basic similarity difference in the structure of the pupils of the black skimmer of North and South America (which is large and slit-shaped) in comparison to its relatives is observed. Adding to the structural difference, a contrasting range is observed in the habitation of these birds.
