Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Mostly smallish herbivores, near-global distribution centered on Palearctic and Americas. Often pronounced sexual dimorphism with males among the most colorful birds alive. Songs tend to be fairly simple warbling and chirping, with many species relying as much or more on visual mating displays.
The thrush is one of the many kinds of small bird that have in the past been trapped and eaten in much of Europe; the practice is now rare. [11] Among traditional ways of cooking thrush were with polenta or grilled on a skewer, in Italy; with juniper berries in Belgium; and made into a pâté or terrine. [11]
The bird feeds on crustaceans, bits of plant material, aquatic insects, mollusks, frogs, newts and very small fish (such as minnows) ignored by larger waders. [ 24 ] [ 25 ] [ 26 ] In Brazil, researchers found roseate spoonbill diets to consist of fish, insects, crustaceans, mollusks, and seeds, all foraged from limnetic /freshwater habitats.
The taxonomic treatment [3] (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) Check-list of North American Birds, the recognized scientific authority on the taxonomy and nomenclature of North America birds.
Buphagus erythrorhynchus on an impala. The oxpeckers are two species of bird which make up the genus Buphagus, and family Buphagidae.The oxpeckers were formerly usually treated as a subfamily, Buphaginae, within the starling family, Sturnidae, but molecular phylogenetic studies have consistently shown that they form a separate lineage that is basal to the sister clades containing the Sturnidae ...
A small number of species are known to make smaller migratory movements, particularly montane species which move to lower altitudes during different seasons. This has been demonstrated using radio tracking in the resplendent quetzal in Costa Rica and evidence has been accumulated for a number of other species. The Narina trogon of Africa is ...
Their soft plumage is cryptically coloured to resemble bark or leaves, and some species, unusual for birds, perch along a branch rather than across it, helping to conceal them during the day. The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings.
