The Blue Tit (Cyanistes caeruleusor Parus caeruleus) is a small passetine bird in the tit family Paridae. The bird is easily recognisable by its blue and yellow plumage.

Blue tits, usually resident and non-migratory birds, are widespread and a common resident breeder throughout temperate and subarctic Europe and western Asia in deciduous or mixed woodlands with a high proportion of oak. They usually nest in tree holes, although they easily adapt to nest boxes where necessary. The main rival for nests and search for food is the much larger Great Tit.The blue tit prefers insects and spiders for their diet. Outside the breeding season, they also eat seeds and other vegetable-based foods. Blue tits are famed for their skill, as they can cling to the outermost branches and hang upside down when looking for food.This is a common and popular European garden bird, due to its perky acrobatic performances when feeding on nuts or suet. It swings beneath the holder, calling "tee, tee, tee" or a scolding "churr".

The Bullfinch, Common Bullfinch or Eurasian Bullfinch (Pyrrhula pyrrhula) is a small passerine bird in the finch family Fringillidae. In Anglophone Europe it is known simply as Bullfinch, as it is the original bird to bear the name bullfinch.

This bird breeds across Europe and temperate Asia. It is mainly resident, but many northern birds migrate further south in the winter.

Mixed woodland with some conifers is favoured for breeding, including parkland and gardens. It builds its nest in a bush, (preferably more than 4 metres tall and wide),mature stands of scrub, or tree, laying four to seven eggs. The food is mainly seeds and buds of fruit trees, which can make it a pest in orchards. Ash and hawthorn are favoured in autumn and early winter. If wild bird cover is planted for it, Kale, Quinoa and Millet are preferred, next to tall hedges or woodland.

The House Sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. One of about 25 species in the genus Passer, the House Sparrow occurs naturally in most of Europe, the Mediterranean region, and much of Asia. Its intentional or accidental introductions to many regions, including parts of Australia, Africa, and the Americas, make it the most widely distributed wild bird. The House Sparrow is strongly associated with human habitations, and can live in urban or rural settings.Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. As an adult, the House Sparrow mostly feeds on the seeds of grains and weeds, but it is opportunistic and adaptable, and eats whatever foods are available. It will eat almost any seeds, but where it has a choice, it prefers oats and wheat. In urban areas, the House Sparrow feeds largely on food provided directly or indirectly by humans, such as bread, though it prefers raw seeds.Animals form another important part of the House Sparrow's diet, chiefly insects, of which beetles, caterpillars, dipteran flies, and aphids are especially important.

The Great Spotted Woodpecker (or Greater Spotted Woodpecker), Dendrocopos major, is a bird species of the woodpecker family (Picidae). It is distributed throughout Europe and northern Asia, and usually resident year-round except in the colder parts of its range.The Great Spotted Woodpecker is 23–26 centimetres (9.1–10 in) long, with a 38–44 centimetres (15–17 in) wingspan. The upperparts are glossy black, with white on the sides of the face and neck. A black line zigzags from the shoulder halfway across the breast (in some subspecies nearly meeting in the center), then back to the nape; a black stripe, extending from the bill, runs below the eye to meet this latter part of the zigzag line. On the shoulder is a large white patch and the flight feathers are barred with black and white. The three outer tail feathers are barred; these show when the short stiff tail is outspread, acting as a support in climbing. The underparts are dull white, the abdomen and undertail coverts crimson. The bill is slate black and the legs greenish grey.The food mainly consists of insects and grubs but also seeds, fruit, scraps, eggs, chicks and small rodents. The woodpecker usually alights on the trunk, working upwards, from side to side, but sometimes will perch in passerine style, when it sits well upright. During the ascent it taps the bark, breaking off fragments, but often extracts its prey from crevices with the tip of its sticky tongue. Beechmast, acorns, nuts and berries are eaten when animal food is scarce.

The Eurasian Nuthatch, Sitta europaea, is a small passerine found throughout temperate Europe and Asia. It belongs to the nuthatch family Sittidae.This bird is the most common and most widespread nuthatch, and is often referred to just as the Nuthatch.

It is a resident bird of deciduous woods and parkland, with some old trees for nesting. It feeds on insects, seeds and nuts. Its old name “nut-hack” derives from its habit of wedging a nut in a crevice in a tree, and then hacking at it with its strong bill.It has the ability, like other nuthatches, to climb down trees, unlike species such as woodpeckers which can only go upwards. It will come to bird feeding tables, and is then very aggressive, driving other species away.The Eurasian Nuthatch is 14 cm long and has the typical nuthatch big head, short tail and powerful bill and feet. It is blue-grey above, with a black eyestripe. Asian and north European birds (S. e. asiatica and S. e. europaea respectively) are white below except for chestnut in the vent area. The western European S. e. caesia has generally reddish underparts. Young birds are "washed out" versions of the adults.

The European Robin (Erithacus rubecula), most commonly known in Anglophone Europe simply as the Robin, is a small insectivorous passerine bird that was formerly classed as a member of the thrush family (Turdidae), but is now considered to be an Old World flycatcher (Muscicapidae). The male and female bear similar plumage; an orange breast and face (more strongly coloured in the otherwise similar British subspecies E. r. mesophilus), lined by a bluish grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly whitish, while the legs and feet are brown. The Robin is diurnal, although has been reported to be active hunting insects on moonlit nights or near artificial light at night.Well known to British and Irish gardeners, it is relatively unafraid of people and likes to come close when anyone is digging the soil, in order to look out for earthworms and other food freshly turned up. Robins also approach large wild animals, such as wild boar and other animals which disturb the ground, to look for any food that might be brought to the surface. In autumn and winter, robins will supplement their usual diet of terrestrial invertebrates, such as spiders, worms and insects, with berries and fruit.They will also eat seed mixtures placed on bird-tables.
