Suet Cake
Suet cakes or fat balls are nutritional supplements for wild birds used in bird feeders. They commonly consist of sunflower seeds and wheat or oat flakes mixed with suet, pork fat, or coconut oil. Further blends may also contain nuts, fruits, mealworms and other insects. In North America, they are one of the most popular choices for bird food, after seed mixes. Next to balls, which are predominantly common in Northern and Central Europe, suet cakes may take various shapes such as rectangles, rings, or wheels. Fat balls are often sold within a fine plastic net allowing their suspension, such as on branches or in bushes. The nets can, however, be a danger to other species, such as deer, who may find the balls and eat them whole. Other forms of suet cakes can be placed within suspendable cages. Composition Suet is the hard fat found around the kidneys and loins of cattle and sheep. Because animal fat is high in energy and easily digested, many birds feed on it, especially in win ...

Parus Caeruleus 5 Luc Viatour
''Parus'' is a genus of Old World birds in the tit family Paridae. It was formerly a large genus containing most of the 50 odd species in the family Paridae. The genus was split into several resurrected genera following the publication of a detailed molecular phylogenetic analysis in 2013. The genus name, ''Parus'', is the Latin word for "tit". Taxonomy The genus ''Parus'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae''. The genus name is Latin for "tit". Of the 12 species included in the genus by Linnaeus, the type species was designated as the great tit (''Parus major'') by George Robert Gray in 1840. Species The genus now contains the following three species: Fossil record *''Parus robustus'' (Pliocene of Csarnota, Hungary) Kessler, E. 2013. Neogene songbirds (Aves, Passeriformes) from Hungary. – Hantkeniana, Budapest, 2013, 8: 37-149. *''Parus parvulus'' (Pliocene ...

Downy Woodpecker
The downy woodpecker (''Dryobates pubescens'') is a species of woodpecker, the smallest in North America. Length ranges from . Downy woodpeckers primarily live in forested areas throughout the United States and Canada, with the exception of deserts in the southwest and the northern tundra. The bird nests in tree cavities and feeds primarily on insects, although it supplements its diet with seeds and berries. The downy woodpecker is very similar in appearance to the hairy woodpecker, although they are not closely related. Taxonomy The downy woodpecker was described and illustrated with a hand-coloured plate by the English naturalist Mark Catesby in his ''The Natural History of Carolina, Florida and the Bahama Islands'', which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition, he included the downy woodpecker, coined the binomial name ''Picus pubescens'' and cited Catesby's book. The specif ...

Invasive Species
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotw ...

Starling
Starlings are small to medium-sized passerine (perching) birds known for the often dark, glossy iridescent sheen of their plumage; their complex vocalizations including mimicking; and their distinctive, often elaborate swarming behavior, known as murmuration. All members of the family ''Sturnidae'', commonly called sturnids, are known collectively as starlings. The Sturnidae are named for the genus '' Sturnus'', which in turn comes from the Latin word for starling, ''sturnus''. The family contains 128 species which are divided into 36 genera. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for ...

Bluebird
The bluebirds are a North American group of medium-sized, mostly insectivorous or omnivorous passerine birds in the genus ''Sialia'' of the thrush family (Turdidae). Bluebirds are one of the few thrush genera in the Americas. Bluebirds lay an average of 4 to 6 eggs per clutch. They will usually brood two or three times in a year. Bluebirds nest from March all the way through August. Bluebirds have blue, or blue and rose beige, plumage. Female birds are less brightly colored than males, although color patterns are similar and there is no noticeable difference in size. Taxonomy and species The genus ''Sialia'' was introduced by the English naturalist William Swainson in 1827 with the eastern bluebird (''Sialia sialis'') as the type species. A molecular phylogenetic study using mitochondrial sequences published in 2005 found that ''Sialia'', '' Myadestes'' (solitaires) and '' Neocossyphus'' (African ant-thrushes) formed a basal clade in the family Turdidae. Within ''Sialia'' t ...

Kinglet
A kinglet is a small bird in the family Regulidae. Species in this family were formerly classified with the Old World warblers. "Regulidae" is derived from the Latin word ''regulus'' for "petty king" or prince, and refers to the coloured crowns of adult birds. This family has representatives in North America and Eurasia. There are six species in this family; one, the Madeira firecrest, ''Regulus madeirensis'', was only recently split from common firecrest as a separate species. One species, the ruby-crowned kinglet, differs sufficiently in its voice and plumage to be afforded its own genus, ''Corthylio''. Description Kinglets are among the smallest of all passerines, ranging in size from and weighing ; the sexes are the same size. They have medium-length wings and tails, and small needle-like bills. The plumage is overall grey-green, offset by pale wingbars, and the tail tip is incised. Five species have a single stiff feather covering the nostrils, but in the ruby-crowned k ...

Thrush (bird)
The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates, and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family. Characteristics Thrushes are plump, soft-plumaged, small to medium-sized birds that inhabit wooded areas and often feed on the ground. The smallest thrush may be the shortwings, which have ambiguous alliances with both thrushes and Old World flycatchers. The lesser shortwing averages . The largest thrush is the great thrush at and ; the larger, commonly recognized blue whistling thrush is an Old world flycatcher. The Amami thrush might, however, grow larger than the great thrush. Most species are gre ...

Junco
A junco (), genus ''Junco'', is a small North American bird in the New World sparrow family Passerellidae. Junco systematics are still confusing after decades of research, with various authors accepting between three and twelve species. Despite having a name that appears to derive from the Spanish term for the plant genus '' Juncus'' (rushes), these birds are seldom found among rush plants, which prefer wet ground, while juncos prefer dry soil. Their breeding habitat is coniferous or mixed forest areas throughout North America, ranging from subarctic taiga to high-altitude mountain forests in Mexico and Central America south to Panama. Northern birds usually migrate farther south; southern populations are permanent residents or altitudinal migrants, moving only a short distance downslope to avoid severe winter weather in the mountains. These birds forage on the ground. In winter, they often forage in flocks. They eat mainly insects and seeds. They usually nest in a well-hid ...

American Goldfinch
The American goldfinch (''Spinus tristis'') is a small North American bird in the finch Family (biology), family. It is Bird migration, migratory, ranging from mid-Alberta to North Carolina during the breeding season, and from just south of the Canada–United States border to Mexico during the winter. The only finch in its subfamily to undergo a complete molt, the American goldfinch displays sexual dichromatism: the male is a vibrant yellow in the summer and an olive (color), olive color during the winter, while the female is a dull yellow-brown shade which brightens only slightly during the summer. The male displays brightly colored plumage during the breeding season to attract a mate. The American goldfinch is a Seed predation, granivore and adaptation, adapted for the consumption of seedheads, with a conical beak to remove the seeds and agile feet to grip the stems of seedheads while feeding. It is a social bird and will gather in large flocks while feeding and migrating. ...

Canada Jay
The Canada jay (''Perisoreus canadensis''), also known as the grey jay, gray jay, camp robber, moose bird, gorby, or whisky jack, is a passerine bird of the family Corvidae. It is found in boreal forests of North America north to the tree line, and in the Rocky Mountains subalpine zone south to New Mexico and Arizona. A fairly large songbird, the Canada jay has pale grey underparts, darker grey upperparts, and a grey-white head with a darker grey nape. It is one of three members of the genus '' Perisoreus'', a genus more closely related to the magpie genus ''Cyanopica'' than to other birds known as jays. The Canada jay itself has nine recognized subspecies. Canada jays live year-round on permanent territories in coniferous forests, surviving in winter months on food cached throughout their territory in warmer periods. The birds form monogamous mating pairs, with pairs accompanied on their territories by a third juvenile from the previous season. Canada jays adapt to human ac ...

Nuthatch
The nuthatches () constitute a genus, ''Sitta'', of small passerine birds belonging to the family Sittidae. Characterised by large heads, short tails, and powerful bills and feet, nuthatches advertise their territory using loud, simple songs. Most species exhibit grey or bluish upper parts and a black eye stripe. Most nuthatches breed in the temperate or montane woodlands of the Northern Hemisphere, although two species have adapted to rocky habitats in the warmer and drier regions of Eurasia. However, the greatest diversity is in Southern Asia, and similarities between the species have made it difficult to identify distinct species. All members of this genus nest in holes or crevices. Most species are non-migratory and live in their habitat year-round, although the North American red-breasted nuthatch migrates to warmer regions during the winter. A few nuthatch species have restricted ranges and face threats from deforestation. Nuthatches are omnivorous, eating mostly insec ...
