Dipper - Cinclus Cinclus
aka Water Ouzel

Dippers are members of the genus Cinclus in the bird family Cinclidae, named for their bobbing or dipping movements. They are unique among passerines for their ability to dive and swim underwater.

They have a characteristic bobbing motion when perched beside the water, giving them their name. While under water, they are covered by a thin, silvery film of air, due to small bubbles being trapped on the surface of the plumage.

Dippers are found in suitable freshwater habitats in the highlands of the Americas, Europe and Asia. In Africa they are only found in the Atlas Mountains of Morocco. They inhabit the banks of fast-moving upland rivers with cold, clear waters, though, outside the breeding season, they may visit lake shores and sea coasts.

The high haemoglobin concentration in their blood gives them a capacity to store oxygen greater than that of other birds, allowing them to remain underwater for thirty seconds or more, whilst their basal metabolic rate is approximately one-third slower than typical terrestrial passerines of similar mass. One small population wintering at a hot spring in Suntar-Khayata Mountains of Siberia feeds underwater when air temperatures drop below −55 °C (−67 °F).

Dippers are completely dependent on fast-flowing rivers with clear water, accessible food and secure nest-sites. They may be threatened by anything that affects these needs such as water pollution, acidification and turbidity caused by erosion. River regulation through the creation of dams and reservoirs, as well as channelization, can degrade and destroy dipper habitat.

Dippers are also sometimes hunted or otherwise persecuted by humans for various reasons. The Cyprus race of the white-throated dipper is extinct. In the Atlas Mountains dippers are claimed to have aphrodisiacal properties. In parts of Scotland and Germany, until the beginning of the 20th century, bounties were paid for killing dippers because of a misguided perception that they were detrimental to fish stocks through predation on the eggs and fry of salmonids.

Blackcap - Sylvia Atrcapilla (M)

The Eurasian blackcap (Sylvia atricapilla) usually known simply as the blackcap, is a common and widespread typical warbler. It has mainly olive-grey upperparts and pale grey underparts, and differences between the five subspecies are small. Both sexes have a neat coloured cap to the head, black in the male and reddish-brown in the female. The male's typical song is a rich musical warbling, often ending in a loud high-pitched crescendo, but a simpler song is given in some isolated areas, such as valleys in the Alps. The blackcap's closest relative is the garden warbler, which looks quite different but has a similar song.
The blackcap feeds mainly on insects during the breeding season, then switches to fruit in late summer, the change being triggered by an internal biological rhythm. When migrants arrive on their territories they initially take berries, pollen and nectar if there are insufficient insects available, then soon switch to their preferred diet. They mainly pick prey off foliage and twigs, but may occasionally hover, flycatch or feed on the ground. Blackcaps eat a wide range of invertebrate prey, although aphids are particularly important early in the season, and flies, beetles and caterpillars are also taken in large numbers. Small snails are swallowed whole, since the shell is a source of calcium for the bird's eggs. Chicks are mainly fed soft-bodied insects, fruit only being provided if invertebrates are scarce.

In July, the diet switches increasingly to fruit. The protein needed for egg-laying and for the chicks to grow is replaced by fruit sugar which helps the birds to fatten for migration. Aphids are still taken while they are available, since they often contain sugars from the plant sap on which they feed. Blackcaps eat a wide range of small fruit, and squeeze out any seeds on a branch before consuming the pulp. This technique makes them an important propagator of mistletoe. The mistle thrush, which also favours that plant, is less beneficial since it tends to crush the seeds. Although any suitable fruit may be eaten, some have seasonal or local importance; elder makes up a large proportion of the diet of northern birds preparing for migration, and energy-rich olives and lentisc are favoured by blackcaps wintering in the Mediterranean.

The German birds wintering in British gardens rely on provided food, and the major items are bread and fat, each making up around 20% of the diet; one bird survived the whole winter eating only Christmas cake. Fruit is also eaten, notably cotoneaster (41% of the fruit consumed), ivy and honeysuckle, and apple if available. Some birds have learned to take peanuts from feeders. Blackcaps defend good winter food sources in the wild, and at garden feeding stations they repel competitors as large as starlings and blackbirds. Birds occasionally become tame enough to feed from the hand.
Aristotle, in his History of Animals, considered that the garden warbler eventually metamorphosed into a blackcap. The blackcap's song has led to it being described as the "mock nightingale" or "country nightingale", and John Clare, in "The March Nightingale" describes the listener as believing that the rarer species has arrived prematurely. "He stops his own and thinks the nightingale/Hath of her monthly reckoning counted wrong". The song is also the topic of Italian poet Giovanni Pascoli's "La Capinera" [The Blackcap].

Giovanni Verga's 1871 novel Storia di una capinera, according to its author, was inspired by a story of a blackcap trapped and caged by children. The bird, silent and pining for its lost freedom, eventually dies. In the book, a nun evacuated from her convent by cholera falls in love with a family friend, only to have to return to her confinement when the disease wanes. The novel was adapted as films of the same name in 1917, 1943 and 1993. The last version was directed by Franco Zeffirelli, and its English-language version was retitled as Sparrow. In Saint François d'Assise, an opera by Messiaen, the orchestration is based on bird song. St Francis himself is represented by the blackcap.

Folk names for the blackcap often refer to its most obvious plumage feature (black-headed peggy, King Harry black cap and coal hoodie) or to its song, as in the "nightingale" names above. Other old names are based on its choice of nesting material (Jack Straw, hay bird, hay chat and hay Jack). There is a tradition of the Royal Navy's Fleet Air Arm bases being named for birds. A former base near Stretton in Cheshire was called HMS Blackcap.

Wood Warbler - Phylloscopus sibilatrix

The wood warbler (Phylloscopus sibilatrix) is a common and widespread leaf warbler which breeds throughout northern and temperate Europe, and just into the extreme west of Asia in the southern Ural Mountains.
This warbler is strongly migratory and the entire population winters in tropical Africa.

It is a summer visitor to the United Kingdom, seen from April until August. It has declined there in recent years. It is now very rare in Ireland, where only one or two pairs are recorded breeding in most years, usually in County Wicklow.

Various factors associated with forest structure, including slope, forest cover, proportion of broad-leaf forest, canopy height and forest edge length, all influenced the occupancy rates of this declining forest species. Conservation measures are therefore required that provide and maintain the wood warblers preferred forest structure. There is also a preference for forest in the non-breeding season, however this habitat is declining in wintering areas such as Ghana. Despite the decline in forest habitats, there has been no change in number of wood warblers as it appears that this species can use degraded habitats, such as well-wooded farms. However, further loss of trees will likely have a negative impact on this species in the future
