Tits are cavity-nesting birds, typically using trees, although Pseudopodoces builds a nest on the ground.

Marsh and Willow Tits are difficult to identify on appearance alone ; the races occurring in the UK ( P. p. dresseri and P. m. kleinschmidti respectively ) are especially hard to separate.

Note the glossy cap, smaller bib and uniform wings which help distinguish it from the Willow Tit. In mixed winter tit flocks, seldom more than one or two Marsh Tits are present, and parties of this species alone are infrequent.

The hidden seeds are prone to being stolen, by other Marsh Tits or other species, so birds often fly from one site to another before deciding on a hiding place.

Marsh Tits are monogamous and often pair for life ; one pair stayed together for six years.

Coal Tits from Asia follow Bergmann's Rule, being larger in colder regions ; those from further west, however, do not, as the birds from the uplands around the Mediterranean are larger than those from northern Europe.

The prison officers, or " screws " as they are called by the women, comprised the firm but fair governor Erica Davidson ( Patsy King ), flanked by the diametrically opposed dour Deputy governor Vera Bennett ( Fiona Spence ), dubbed " Vinegar Tits " by the inmates, and compassionate senior officer Meg Jackson ( Elspeth Ballantyne ).

Research published in 2007 found that Blue Tits on the eastern Canary Islands of Fuerteventura and Lanzarote are indistinguishable from those in North Africa and so the subspsecies degener should be regarded as a synonym of ultramarinus.

Young Blue Tits are noticeably more yellow.

Blue and Great Tits form mixed winter flocks, and the former are perhaps the better gymnasts in the slender twigs.

Blue Tits are able to culturally transmit learning to other Tit species.

Blue Tits are known to be host to feather mites, and rarely lice and flat flies.

Other than those species formerly considered to be subspecies, the Great Tit's closest relatives are the White-naped and Green-backed Tits of southern Asia.

Mixed-forests are one of the habitats Great Tits use in Europe.

Great Tits are primarily insectivorous in the summer, feeding on insects and spiders which they capture by foliage gleaning.

Great Tits are monogamous breeders and establish breeding territories.

Great Tits are seasonal breeders.

Great Tits are cavity nesters, breeding in a hole that is usually inside a tree, although occasionally in a wall or rock face, and they will readily take to nest boxes.

The nests of Great Tits are raided by Great Spotted Woodpeckers, particularly when nesting in certain types of nest boxes.

Tits proved a remarkable theorem: all spherical buildings of rank at least three are connected with a group ; moreover, if a building of rank at least two is connected with a group then the group is essentially determined by the building.

Tits proved that all irreducible spherical buildings ( i. e. with finite Weyl group ) of rank greater than 2 are associated to simple algebraic or classical groups.

For example, Great Tits and House Sparrows are vulnerable to attack.

A study of Marsh Tits in Białowieża Forest, Poland, looked at which factors affected birds ' choice to re-occupy a nest hole used the previous year.

Insularity also affects clutch size, with Great Tits on offshore islands laying smaller clutches with larger eggs than mainland birds.

The Gardens provides homes for a number of birds, including Great Tits, Robins, Magpies, and Blackbirds.

Most burrow-nesting birds excavate their own burrows, but some use those excavated by other species ; Burrowing Owls, for example, sometimes use the burrows of prairie dogs, ground squirrels, badgers or tortoises, China's endemic White-browed Tits use the holes of ground-nesting rodents and Common Kingfishers occasionally nest in rabbit burrows.

The Azure Tit frequently hybridizes with the Blue Tit in western Russia ; the resulting birds are called " Pleske's Tits " ( Cyanistes × pleskei ) and were once considered a distinct species.

A study of the foraging ecology of alpine forest birds on conifers in the Taroko National Park found that, when compared with Eurasian Nuthatches, Coal Tits, Green-backed Tits and Black-throated Tits, Flamecrests were the most generalised foragers, utilising almost all of the crown of a tree, rather than specialising in parts of it as with the other species, with which it associates in mixed-species foraging flocks during the non-breeding season.

The park has a rich flora and fauna: birds include: Blue Tits, blackbirds, swallows, robins, magpies and the omnipresent sparrows and pigeons on the north and northwestern edge of the park.

The position was given to Jacques Tits.

Variations in the exploratory behaviour of Great Tits ( Parus major ) have been found to be linked with a gene orthologous to the human gene DRD4 ( Dopamine receptor D4 ) which is known to be associated with novelty-seeking behaviour.

*: The Tits group is generally considered of this form, though strictly speaking it is not of Lie type, but rather index 2 in a group of Lie type.

The alder carr and willow carr support the Swallowtail Butterfly and the Norfolk hawker dragonfly Aeshna isosceles, as well as Marsh Harriers, Bearded Tits and most of the country's Cetti's Warblers.

The Critical Mass rides have inspired a number of other bicycle movements, that range from political movements to the " Critical Tits " ride during the yearly Burning Man festival.

In Britain, Great Tits and Blue Tits famously learned to break open the foil caps sealing bottles of milk that had been delivered to homes to get at the cream floating on top.

Tits also have a variety of methods for attracting mates, primarily through their intricate, bouncing mating dance.

Tits have settled North America twice, probably at some time during the Early-Mid Pliocene.

She wrote and drew short stories for Wimmen's Comix and many other anthologies, including Tits & Clits Comix, Wet Satin, and Anarchy Comics.

The Marsh Tit Poecile palustris is a passerine bird in the tit family Paridae and genus Poecile, closely related to the Willow, Père David's and Songar Tits.

Plumage characteristics include the lack of a pale wing panel ( formed by pale edges to the secondary feathers in the Willow Tit ), the Marsh Tit's glossier black cap and smaller black ' bib ', although none of these is ' completely reliable '; for example, juvenile Marsh Tits can show a pale wing panel.
