Songbirds, are a group of birds among which are grouped in the group of Passeriformes or with the name of Oscines, where they are composed of more than 5,000 species or even much more. In the following article we will know more about these birds and how they are taxonomically organized.

Definition of Songbirds

Songbirds are songbirds belonging to the Passeri clade of perching birds called Passeriformes. Another name that is sometimes seen as a scientific or vernacular name is Oscines, from the Latin oscen, “a songbird”. This group contains some 5,000 or more species found worldwide, in which the vocal organ is typically developed in such a way as to produce a diverse and elaborate bird song.

Songbirds form 1 of the 2 main lineages of perching birds, the other being the Tyranni, which is very diverse in the Neotropics and is absent in many parts of the world. The Tyranni have a Syrinx musculature that is simpler, and although their vocalizations are often as complex and as striking as those of the Songbirds, they are on the whole more mechanical.

There is a third lineage of perching birds, the Acanthisitti of the New Zealand regions, of which only 2 species remain alive today. Some evidence tends to suggest that songbirds came to evolve more than 50 million years ago in the part of Gondwana that later became India, Sri Lanka, Australia, New Zealand, New Guinea and Antarctica, before eventually spreading around the world.

The Songbird or Songbirds, also called passerines, are any member of the suborder Passeri or Oscines, of the order Passeriformes, which includes about 4,000 species and is almost half of the world’s birds from about 35 to 55 families. Most cage birds belong to this group.

Songbirds are similar in having a highly developed vocal organ, although not all use it to melodious effect. Classification in this suborder is currently much debated. There are 2 families that are very distinctive which are:


Song in this clade is essentially territorial, because it communicates the identity and whereabouts of an individual to other birds, and also signals the sexual intentions of the birds. Sexual selection among songbirds is highly based on mimetic vocalization. Female preference has been shown in some populations to be based on the extent of the song repertoire of male birds.

The larger a male’s repertoire, the more females a male individual attracts. Not to be confused with bird calls that are used for alarms and contact calls, and are especially important in birds that feed or migrate in flocks. While nearly all living birds give calls of some kind or type, well-developed songs are only given by a few lineages outside the Songbirds.

Other birds, especially those that are not passerines, sometimes have songs to attract mates or to maintain territory, but these are usually simple and repetitive, and lack the variety of many oscine songs. The monotonous repetition of the common cuckoo or small crake can be contrasted with the variety of a Nightingale or marsh warbler. On the other hand, although many of the Songbirds possess songs pleasing to the human ear, but this is not always the case.

Many members of the crow family ( Corvidae ) communicate with a squawk or squawk, which sounds harsh to humans. Even these, however, have a kind of song, a softer kind of chirping that occurs between courtship partners.

And although some of the parrots that are not songbirds can learn to repeat human speech, vocal mimicry among birds is almost entirely restricted to songbirds, some of which, such as dormice or mockingbirds, excel at imitating the sounds of other birds or even environmental noises.


Although the group is quite homogeneous, it is also very complex in detail, and the secondary divisions are often hotly debated at present. The order presents about 3 suborders in:

First a reduced basal group, the Acanthisitti, and 2 major groups that were traditionally established by the alignment of the legs and their song organ

Secondly the Tyranni or songbirds, which have a syrinx that is very simple

Third the Passeri, or songbirds stricto sensu, whose syrinx has a complex system of muscles to control it, although it includes among the species such as the crows, which do not sing. In the following we will name the orders with their respective groups:

Order Passeriformes

Suborder Acanthisitti

Suborder Passeri

Passeri basales

Superfamily Corvoidea

Corvoidea incertae sedis

  • “Pitohuidae”: traditionally included in the Pachycephalidae, but apparently they are more closely related to the Oriolidae and may come to be considered as a distinct family including Oreoica and possibly other members of the Pachycephalidae sensu lato.

Infraorder Passerida

Suborder Tyranni

Infraorder Eurylaimides: Old World suboscines.

Infraorder Tyrannides: New World suboscines; according to Ohlson et al. (2013), this infraorder can be organized as follows:

Superfamily Thamnophiloidea

Superfamily Furnarioidea

  • Furnariidae: horneros, ticoticos, pijuíes, espineros and related species.

Parvorden Tyrannida

Superfamily Tyrannoidea

  • Tyrannidae: flycatchers, tyrannids, flycatchers, flycatchers and related.

With songbird calls ranging from sweet to demanding, there are many types of songbirds in North America. From the common American robin to the brightly colored Blue Jay.

Bird vocalization includes bird songs. In non-technical usage, bird songs are sounds that are melodious to the human ear. In ornithology and bird watching, songs i.e. relatively complex vocalizations come to be distinguished by functions from calls that are relatively simple vocalizations.

Vocalization in birds includes a wide variety of calls in addition to the song itself and provides a means of social communication. Song in songbirds is best regarded as the vocalization used in courtship and breeding, primarily by the male, to announce that he is ready to mate, to attract the female and perhaps to stimulate her sexually, also to keep the pair together, and to inform rival males that he has established a territory from which they will be excluded.

Male calls are also part of a kind of threat display that takes the place of actual combat in order to repel intruding rivals. However, a similar song sometimes occurs spontaneously when there is no obvious use for it. Occasionally, females sing, and especially this occurs in tropical species, pairs may duet, again perhaps as a kind of method of reinforcing the bond between the pair.

Often, the song is delivered from a series of regularly used perches. Some of the species, especially those inhabiting grasslands, possess the flight songs.

The song of the bird need not be pleasing to the human ear. The hooting of the owl, the monotonously repeated phrases of the North American whippoorwill, the maddeningly repeated whistling of a Malay cuckoo which has given it the name of the brain-fever bird, and the repeated notes of the African tinkerbird, which, by their similar hammering on metal, have given the bird its name; all must be called songs.

Courtship Songs

Sexual selection can come to be divided into several different studies of the various aspects of a bird’s song. As a result, song can come to vary even within a single species. Many tend to believe that song repertoire and cognition have a direct relationship. However, a study conducted and published in 2013 has shown that all cognitive ability may not be directly related to song repertoire in Songbirds.

Specifically, spatial learning is said to have an inverse relationship with song repertoire. So, for example, this would be an individual that does not migrate as far as others in the species, but has a better song repertoire. This suggests a kind of evolutionary trade-off between possible alleles.

The song repertoire can be attributed to male songbirds, as it is one of the main courtship mechanisms. Song repertoires differ from individual male to individual male and from species to species. Some of the species may have large repertoires, while others may have significantly smaller repertoires. Mate choice in Songbirds is an important field of study as song abilities are constantly evolving.

At present there have been numerous studies involving the repertoires of songbirds, unfortunately, there is still concrete evidence to confirm that each species of songbird prefers larger repertoires. It can be concluded that it may come to vary between specific species as to whether a larger repertoire is connected to better fitness.

With this conclusion, it can be inferred that evolution through natural selection, or sexual selection, During times of courtship, male songbirds or Songbirds are said to increase their repertoire by imitating songs of other species. Improved imitation ability, retention ability and the amount of other species imitated have been shown to have a positive relationship with mating success. Female preferences cause constant improvement in the accuracy and presentation of copied songs.

Migratory Songbirds

According to the strict definition given above, there are about 200 species of migratory birds that are neotropical. Most of them are songbirds, i.e., songbirds such as, for example:

But there are also several birds that are shorebirds which we can mention the:

We can also mention some of the migratory birds of prey such as:

And some types of aquatic birds such as the blue-green.

Most songbirds and long-distance migratory shorebirds, and some waterfowl, migrate at night when weather conditions are more favorable with cooler temperatures and calmer air and predators are few.

While nocturnal migrants, i.e., those that tend to migrate at night, travel through the air by flapping their wings, among them hawks and vultures fly in such a way that they soar and glide on rising air currents.

These soaring birds must migrate during the day, since the updrafts that allow them to fly form only during the day as the sun’s rays warm the earth. Swallows, swifts and nighthawks are also diurnal migrants, that is, they migrate during the day and not only at night because they feed on flying insects that are only active during the day.

In general, nocturnal migratory songbirds travel at higher altitudes than daytime migrants. Of the nocturnal migrants, most shorebirds and waterfowl fly higher on average than Songbirds. Most birds tend to fly higher when crossing large bodies of water than when flying over land.

The Nature of Your Journey

Songbirds winter in the tropics, coming north to spend the summer in the United States and Canada. These birds, dozens of species of warblers, thrushes, vireos, orioles, flycatchers, tanagers, grosbeaks, and many more, are the ones that migrate mainly at night.

They take off just after dusk, fly during the night and land near dawn, if they are over land at that point, if they are over water, of course, they continue. They can cover 321,869 km or more during a night flight, and when they come down, they need to rest, feed and build up their strength for the next flight.

These birds have incredible navigational powers. A blackburnian warbler, for example, might fly from Maine to Ecuador in the fall, returning in spring to the same tree in Maine where it sang the previous year. But during their night flights they are subject to wind and weather, so in the morning they can descend virtually anywhere. If they still have energy left, they may fly several miles after sunrise, looking for a patch of woods, marshes or meadows.

But eventually, each bird will settle for any place it can find, and that place will have to serve as its temporary stopover habitat.

Where to Find these Migrants

Most migratory Songbirds inhabit trees and shrubs, so they will settle for even a tree or shrub, at least temporarily, if they have no other choice. A Horned Woodpecker and 2 American Redstarts were once seen in the bushes of a small planter in a bank building in downtown Philadelphia.

Small city parks very often tend to host a good variety of songbirds i.e. migratory Songbirds; the surrounding square miles of concrete serve to concentrate the birds, as weary migrants gravitate to the small patches of greenery. Isolated trees in city yards or hotel courtyards can act as stopover habitat for small birds passing through.

Very large patches of habitat, such as large parks or wooded areas, may be better for birds but more challenging for birders, as migrants become more difficult to find in those surroundings. Songbirds in stopover habitat often gather in large mixed flocks, so if you don’t find yourself seeing birds, keep moving until you can find a migrant bird, then look around to see if you have any company.

When to look for these Birds

Because these birds travel at night, early morning is when they are most likely to be seen in marginal habitats.Later in the day, they may have continued to look for other locations with taller trees or thicker brush. If a person has a backyard or nearby park with only a few trees, he or she can try checking them first thing in the morning to see if new visitors have arrived during the night.

Some nights produce much more bird traffic than others. The weather should be watched to look for good flying nights. The ideal night in the spring will be when areas to the south have clear skies, warm temperatures and steady southerly winds. If storms move in during the latter part of the night, rain will cause birds to drop wherever they are at that point. A wet morning after evening showers can produce a bonanza of new migrants in your local trees.

Most people don’t see migratory birds because they aren’t looking for them. You can increase your chances simply by being aware of the possibilities. You should obtain a list of birds from your local Audubon chapter. If you want to see migratory songbirds, you should find out which birds pass through the regions where you live and be prepared for the migration times of migratory bird groups.

And, above all, take a second look at any bird you notice. That brown bird under the hedge might not be one of the local town sparrows, it could be a Swainson’s Thrush just in from Panama. That yellowish bird in the tree might not be a local goldfinch; it could be a Cape May warbler that just arrived from Jamaica. This time of year, migratory songbirds are everywhere, pausing for a moment in virtually every tree. Just by paying attention, you can get to know some amazing world travelers.


The famous taxonomy of Sibley and Ahlquist divided the Songbirds into 2 “parvorders”, Corvida and Passerida. Standard taxonomic practice would classify these as infraorders. Subsequent molecular studies, however, show that this treatment is somewhat erroneous. The Passerida is a broad lineage, including more than ? of all bird species around some 3,885 Passerida species in 2015.

These are divided into 3 main superfamilies although they do not correspond exactly to the arrangement made by Sibley and Ahlquist, plus some minor lineages. On the contrary, Sibley and Alquist’s “Corvida” is a phylogenetic grade, and an artifact of the phenethymethodology.

Most of these form the large superfamily Corvoidea i.e. of about 812 species in 2015, which is a sister group of the Passerida family. The remaining ones which are 15 oscine families consisting of about 343 species in 2015 form a series of basally branching sister groups to the Corvoid – clade Passerid.

All of these groups, which form at least 6 successively branching basal clades, are found exclusively or predominantly in Australasia. Australian endemic species are also prominent among the basal lineages in the Corvoids and Passerids, suggesting that songbirds or songbirds originated and diverged in Australia.


Songbirds range in size from small kinglets and solitary birds to comparatively large crows. They are primarily terrestrial birds that live in a wide variety of situations, from open grasslands to woodlands. Although songbirds include some of the best singers, such as thrushes, some have harsh voices like crows, and some sing little or not at all. Songbirds are distinguished from other roosting birds by certain anatomical features, especially the more complicated vocal organ, the osyrinx.
