مُساهمةsnow pigeon

The snow pigeon (Columba leuconota) is a species of bird in the Columba genus in the family Columbidae from hilly regions of central Asia.


Description
Snow pigeons have a blackish head contrasting with white neck collar and white underparts shading into ashy on the abdomen. Their backs are brownish grey with a white patch on the lower back. Their wings are pale grey with three brown bands. Their black tails have a clear white band in the middle which narrows and curve forward to reach the tip of outermost tail features. Young birds have narrow, pale buff margins to the feathers of the upper parts and wings. The white of the underparts is sullied with buff.

Distribution and status
They are resident birds in rocky hills of Afghanistan, Bhutan, China, India, Kazakhstan, Myanmar, Nepal, Pakistan, Tajikistan, and Turkmenistan. It is a common bird and has an extremely large range. The population is believed to be stable, and for these reasons, the International Union for Conservation of Nature has assessed its conservation status as being of least concern.

Behaviour and ecology
They frequent rocky hill sides and sequestered valleys, seen up to the snow line. They frequently feed in the fields during the day, but roost in the cliffs. They are generally shy and wary. Gatherings of 150 or more occur in winter, often in company of hill pigeon and in some areas with rock pigeon, too.

In the summer, they descend to lower heights and are found in pairs or small flocks. They breed in colonies. The nests are placed in crevices or caves in the face of cliffs or ledges of rock. Their nests are untidy interlaced structures made of sticks, grass, straw, feathers, etc. The nests are generally reused every year with minor repairing. Generally, two eggs are laid.

They feed on berries, grain, buds, bulbs, seeds, and shoots.

Atlantic tripletail
مُساهمة الخميس أغسطس 20, 2020 8:07 pm  عالم الطبيعة
The Atlantic tripletail or tripletail (Lobotes surinamensis) is a warm-water marine fish found across the tropics; it can grow to 90 cm long and weigh 18 kg. It is also known by fishermen by names like flasher or steamboat. Young fishes float on their sides, often beside flotsam, and appear like a dry leaf. In Indonesia, the local name is called KakapHitam  Laut or similar as Black Barramundi which is commonly consumed by its similar appearance as Lates calcalifers-Baramundi


The Atlantic tripletail is the only fish in the Lobotidae family that can be found in the Atlantic Ocean. It is, however, distributed across tropical seas especially Indonesia region which is commonly found in wet market in Pontianak, West Borneo.

In US waters, Atlantic tripletails are found from Massachusetts and Bermuda to Argentina, the eastern Atlantic and Mediterranean Sea, from Madeira Island to the Gulf of Guinea, the eastern Pacific from Costa Rica to Peru, and the western Pacific from Japan to Fiji and Tuvalu. They are rarely found north of Chesapeake Bay. They are found on the Gulf Coast from April to October and then migrate to warmer waters during winter. In the spring, tripletails concentrate just offshore of two particular spots: Port Canaveral, Florida (March–June) and Jekyll Island, Georgia (April–July).


Atlantic tripletails are found coastally in most, but not all, tropical and subtropical seas. They are semimigratorial and pelagic. Normally solitary, they have been known to form schools. They can be found in bays, sounds, and estuaries during the summer. Juveniles are usually found swimming under patches of Sargassum algae. In the Gulf of Mexico, adults are usually found in open water, but can also be found in passes, inlets, and bays near river mouths. Large adults are sometimes found near the surface over deep, open water, although always associated with floating objects. Young fishes are also often found in or near shipwrecks, beams or supports, jetties, flotsam and sea buoys. Fry are usually found in waters that exceed 84 °F (29 °C), greater than 3.3‰ salinity, and more than 230 feet (70 m) deep.

Tripletails are well known for their unusual behavior of floating just beneath the surface with one side exposed, mimicking a leaf or floating debris. This is thought to be a feeding strategy because of the locality of their prey items and the floating structures associated with this behavior. The behavior has resulted in a rapidly increasing incidence of recreational fishermen sight-fishing for the floating tripletails, resulting in severe bag and length restrictions in Florida and Georgia to ensure future populations.

Distinctive features
The Atlantic tripletail has scales that extend onto its dorsal, anal, and caudal fins and a head profile that concaves as the fish ages. It has a compressed but deep body with a triangle-shaped head. The eyes are small, but the mouth is large. The bases of the dorsal and anal fins are scaled and the pectoral fins are shorter than the pelvic fins. The name "tripletail" is given because of the fish's three rounded fins: dorsal, caudal, and anal.

Coloration
Juvenile Atlantic tripletails are colored a mottled yellow, brown, and black. Adults are jet black. When it lies on its side at the surface, the tripletail is sometimes confused for a floating mangrove leaf. The juveniles have white pectoral fins and a white margin on their caudal fins. Adult tripletails have varied mottled color patterns which range from dark brown to reddish brown, often with a tint of gray.

Size, age, and growth
The Atlantic tripletail grows to 35 in (89 cm) in length and weighs up to 41 lb.

Diet
Atlantic tripletails are opportunistic eaters; they feed on a variety of foods, mostly small finfish such as gulf menhaden, Atlantic bumpers, and anchovies. They also feed on invertebrates such as blue crabs and brown shrimp, as well as other benthic crustaceans.

Reproduction
Spawning primarily occurs in the summer along both the Atlantic and the U. Gulf of Mexico coasts, with peaks during July and August. Large congregations of tripletails during the summer months in the inshore and nearshore waters of coastal Georgia suggest this area is a critical estuarian spawning habitat for the species. Larval Atlantic tripletails go through four levels of development; preflexion, flexion, postflexion, and transformation. By the time the larvae reach 0.16 in (4 mm), they have large eyes and concave heads. The larval forms of Atlantic tripletails resemble those of boarfishes, some jacks, spadefishes, and bass.

Predators
Atlantic tripletails do not have many predators, but the main ones are sharks and larger teleosts.

Parasites
Parasites of the tripletail include the copepods Anuretes heckelii which affects the branchial cavities, Lernanthropus pupa which affects the gill filaments, and Scianophilus tenius.

Importance to humans
A few tons of Atlantic tripletails are fished commercially on the east and west coasts o

lesser goldfinch
مُساهمة الخميس أغسطس 20, 2020 8:11 pm  عالم الطبيعة
The lesser goldfinch (Spinus psaltria) is a very small songbird of the Americas. Together with its relatives the American goldfinch and Lawrence's goldfinch, it forms the American goldfinches clade in the genus Spinus sensu stricto.

The American goldfinches can be distinguished by the males having a black (rarely green) forehead, whereas the latter is (like the rest of the face) red or yellow in the European goldfinch and its relatives. North American males are markedly polymorphic and 5 subspecies are often named; at least 2 of them seem to represent a less-progressed stage in evolution however.

It is 10 to 11 centimeters in length and weighs 9 grams
Males are bright yellow below with a glossy black cap and white patches in the wings; their backs can be glossy black or dull green (particularly on the West Coast). They have a black tail with large, white corners. Females and immatures have olive backs, dull yellow underparts, and black wings marked by two whitish wingbars.


Behavior
Lesser Goldfinches gather in groups of up to several hundred at a time. They feed on seeds and grains, both in weedy fields and at bird feeders. Their flocks mix with other seed-eating songbirds, especially at bird feeding stations.

Habitat
Lesser Goldfinches feed in weedy fields, budding treetops, and the brush of open areas and edges. Depending on food availability, they may concentrate in mountain canyons and desert oases, but they are also fairly common in suburbs.


Diet
Mostly seeds, some insects. Majority of diet at all seasons consists of seeds. Especially favors those of the daisy (composite) family, such as thistle and wild sunflower, also seeds of various weeds. Also feeds on flowers and buds of trees (such as cottonwoods) and on some berries. Eats some insects, especially in summer, mainly small ones such as aphids. Will feed on salt.


Nesting
In warmer parts of Southwest, breeding season may extend over much of year from early spring to mid-autumn. In courtship, male feeds female; performs display flight with wings and tail spread widely, fluttering rapidly while singing. Nest: Usually placed in vertical fork of twigs in shrub or tree, 5-30' above the ground, sometimes higher in tree or very low in bushes or dense weeds. Nest (built mostly or entirely by female) is a compact open cup woven of grass, plant fibers, strips of bark, lined with plant down.

Eggs
4 to 5, sometimes 3 to 6. Pale blue to pale blue-green, usually unmarked. Incubation is by female only, about 12 days. Male may feed female during incubation. Young: Both parents feed the nestlings. Age at which young leave nest is not well known. 2 broods per year, perhaps sometimes 3.


Young
Both parents feed the nestlings. Age at which young leave nest is not well known. 2 broods per year, perhaps sometimes 3.
