Biodiversity around my town (1)

  4. 4. goldcrest <ul><li>1. This kinglet has greenish upper-parts, whitish under-parts, and has two white wingbars. It has a plain face contrasting black irises and a bright head crest, orange and yellow in the male and yellow in the female, which is desplayed during breeding. 2. The Goldcrest breeds in coni ferous woodland and gardens, building its compact, three-layered nest on a tree branch. Ten to twelve eggs are incubated by the female alone, and the chicks are fed by both parents; second broods are common. </li></ul>Old drawing of a nest and small branches of a conifer tree
  5. 5. <ul><li>Several subspecies are recognised across the very large distribution range that includes much of Eurasia and the islands of Macaronesia . Birds from the north and east of its breeding range migrate to winter further south . </li></ul>Breeding summer visitor Resident year-round Winter visitor (ranges are approximate)
  6. 6. Black woodpecker
  7. 7. Black woodpecker <ul><li>1. The plumage of this crow-sized woodpecker is entirely black apart from a red crown. In males, the entire crown is red, but in females only the top hindcrown is red with the rest of the body all black. It has a very long beak of 2.5 inches (6.3 cm). The sexes differ even as nestlings. 2. The woodpecker feeds by using its bill to hammer on dead trees to dig out carpenter ants and wood-boring grubs.Their voice is remarkable in that it has two different calls. One is a short single high-pitched note done only twice in a row. The other is a screech-like shrill while in flight. </li></ul><ul><li>Unlike other woodpecker species, the Black Woodpecker does not have a dipping, bounding flight.The woodpecker digs a nest hole, usually in a live poplar or pine tree where it lays four or more eggs . </li></ul>

  9. 9. Bullfinch
  10. 10. Bullfinch <ul><li>- Pyrrhula is a small genus of passerine birds, commonly called Bullfinches , belonging to the finch family (Fringillidae). - The genus has a palearctic distribution. All species occur in Asia with two species exclusively in the Himalayas and one species, P. pyrrhula , also occurring in Europe. - Bullfinches have glossy black wings and tail feathers. They show a white rump. The legs and feet are fleshy brown. Their short, swollen bill is adapted to eat buds, and is black except in P. nipalensis , which has a yellowish bill. The males can be distinguished by their orange or red breast. Some species have a black cap. </li></ul>
  11. 11. Shore Lark
  12. 12. Shore Lark <ul><li>- The Shore Lark ( Eremophila alpestris ),is a species of bird in the genus Eremophila. - Unlike most other larks, this is a distinctive-looking species on the ground, mainly brown-grey above and pale below, with a striking black and yellow face pattern. - The Shore Lark breeds across much of North America from the high Arctic south to the Isthmus of Tehuantepec, northernmost Europe and Asia and in the mountains of southeast Europe. </li></ul>

  14. 14. Crossbill
  15. 15. Crossbill <ul><li>- The crossbills are birds in the finch family Fringillidae. The three to five (or possibly many more) species are all classified in the genus Loxia . These birds are characterised by the mandibles crossing at their tips, which gives the group its English name. Adult males tend to be red or orange in colour, and females green or yellow, but there is much variation. </li></ul><ul><li> - These are specialist feeders on conifer cones, and the unusual bill shape is an adaptation to assist the extraction of the seeds from the cone. These birds are typically found in higher northern hemisphere latitudes, where their food sources grows. They will erupt out of the breeding range when the cone crop fails. Crossbills breed very early in the year, often in winter months, to take advantage of maximum cone supplies. </li></ul>

  17. 17. Raven
  18. 18. Raven <ul><li>Habitat </li></ul><ul><li>Common ravens prefer open landscapes, such as treeless tundra, seacoasts, open riverbanks, rocky cliffs, mountain forests, plains, deserts, and scrubby woodlands. However, these ravens can be found in most types of habitats except for rainforests. Physical Description Common ravens are large, black birds with a wedge-shaped tail. They have a well-developed ruff of feathers on the throat, which are called 'hackles' and are used often social communication. These are the largest passerines. Adults reach up to 69 cm in length and from 689 to 1625 grams in weight . </li></ul>

  20. 20. Common Kestrel
  21. 21. Common Kestrel <ul><li>- The Common Kestrel ( Falco tinnunculus ) is a bird of prey species belonging to the kestrel group of the falcon family Falconidae. - This species occurs over a large range. It is widespread in Europe, Asia and Africa, as well as occasionally reaching the east coast of North America. - Common Kestrels measure 32–39 cm (13–15 in) from head to tail, with a wingspan of 65–82 cm. Their plumage is mainly light chestnut brown with blackish spots on the upperside and buff with narrow blackish streaks on the underside; the remiges are also blackish. Unlike most raptors, they display sexual colour dimorphism with the male having less black spots and streaks, as well as a blue-grey cap and tail. The tail is brown with black bars in females, and has a black tip with a narrow white rim in both sexes. All Common Kestrels have a prominent black malar stripe like their closest relatives. </li></ul>Common kestrel eggs

  23. 23. Owl
  24. 24. Owl <ul><li>- Owls are the order Strigiformes, constituting 200 extant bird of prey species . - Owls have large forward-facing eyes and ear-holes, a hawk-like beak, a flat face, and usually a conspicuous circle of feathers, a facial disc, around each eye. - Most owls are nocturnal, actively hunting for prey only in the darkness. Several types of owl, however, are crepuscular, active during the twilight hours of dawn and dusk; one example is the pygmy owl . </li></ul>

  26. 26. Buzzard
  27. 27. Buzzard <ul><li>- The Common Buzzard ( Buteo buteo ) is a medium to large bird of prey, whose range covers most of Europe and extends into Asia. - It is typically between 51–57 cm in length with a 110 to 150 cm (1 metre to a metre and half) (48–60 inch) wingspan, making it a medium-sized raptor. There are around 40,000 breeding pairs in Britain. It is usually resident all year, except in the coldest parts of its range, and in the case of one subspecies. - It breeds in woodlands, usually on the fringes, but favours hunting over open land. It eats mainly small mammals, and will come to carrion. </li></ul>

  29. 29. Great Tit
  30. 30. Great Tit <ul><li>- The Great Tit ( Parus major ) is a passerine bird in the tit family Paridae. It is a widespread and common species throughout Europe, the Middle East, Central and Northern Asia, and parts of North Africa in any sort of woodland. - The Great Tit is a distinctive bird, with a black head and neck, prominent white cheeks, olive upperparts and yellow underparts, with some variation amongst the numerous subspecies. - The Great Tit's willingness to use bird-feeders and nesting boxes makes it popular with the general public and useful to scientists. The Great Tit is a popular garden bird due to its acrobatic performances when feeding on nuts or seed . </li></ul>
