Magpie
Magpies are intelligent birds of the corvidae familia, including the black and white Eurasian Magpie, which is one of the few animal species known to be able to recognize itself in a mirror test. Other include the Black-billed Magpie, Yellow-billed Magpie and Korean Magpie of the Pica genus, the Formosan Blue Magpie, Red-billed Blue Magpie and Gold-billed Magpie of the Urocissa and also the Common Green Magpie, Yellow-breasted Magpie, Short-tailed Magpie of the Cissa genus.
The jackfruit
The jackfruit (alternately jack tree, jakfruit, or sometimes simply jack or jak; scientific name Artocarpus heterophyllus), is a species of tree in the Artocarpus genus of the mulberry family (Moraceae). It is native to parts of South and Southeast Asia, and is believed to have originated in the southwestern rain forests of India, in present-day Kerala, coastal Karnataka and Maharashtra. The jackfruit tree is well suited to tropical lowlands, and its fruit is the largest tree-borne fruit, reaching as much as 80 pounds (36 kg) in weight and up to 36 inches (90 cm) long and 20 inches (50 cm) in diameter.
Water Lily
Water Lily is the national flowers of our country . The Lily grow in watery places .It is white and pink in colours . When lily is bloomed, the whole marshy land seems to be a wonderland of beauty.
Water lilies are one of the most easily recognized of all the aquatic plants. Beautiful large white or occasionally pink many-petaled flowers float on the water's surface surrounded by large, round green leaves.
Water lily is a floating-leaved aquatic perennial herb that grows rooted in mucky or silty sediments in water up to six to seven feet deep. It prefers quiet waters such as ponds, lake margins, and slow streams and will grow in acid or alkaline waters.

The Royal Bangal Taiger :
Tigers in Bangladesh are now relegated to the forests of the Sundarbans and the Chittagong Hill Tracts. The Chittagong forest is contiguous with tiger habitat in India and Myanmar, but the tiger population is of unknown status.
As of 2004, population estimates in Bangladesh ranged from 200 to 419, mostly in the Sunderbans.This region is the only mangrove habitat in this bioregion, where tigers survive, swimming between islands in the delta to hunt prey. Bangladesh's Forest Department is raising mangrove plantations supplying forage for spotted deer. Since 2001, afforestation has continued on a small scale in newly accreted lands and islands of the Sundarbans. From October 2005 to January 2007, the first camera-trap survey was conducted across six sites in the Bangladesh Sundarbans to estimate tiger population density. The average of these six sites provided an estimate of 3.7 tigers per 100 km2 (39 sq mi). Since the Bangladesh Sundarbans is an area of 5,770 km2 (2,230 sq mi) it was inferred that the total tiger population comprised approximately 200 individuals. In another study, home ranges of adult female tigers were recorded comprising between 12 and 14 km2 (4.6 and 5.4 sq mi)., which would indicate an approximate carrying capacity of 150 adult females. The small home range of adult female tigers (and consequent high density of tigers) in this habitat type relative to other areas may be related to both the high density of prey and the small size of the Sundarbans tigers.
Since 2007 tiger monitoring surveys have been carried out every year by WildTeam in the Bangladesh Sundarbans to monitor changes in the Bangladesh tiger population and assess the effectiveness of conservation actions. This survey measures changes in the frequency of tiger track sets along the sides of tidal waterways as an index of relative tiger abundance across the Sundarbans landscape.
Some interesting facts:
1. Since tigers hunt mostly at dusk and dawn their stripes help them hide in the shadows of tall grasses. They stalk and pounce because they are not able to chase prey a long distance.
2. The territorial male tiger usually travels alone, marking his boundaries with urine, droppings, and scratch marks to warn off trespassers.
3. A tiger can consume as much as 40 kg (88 lb.) of meat in one feeding.
4. Tigers may drag their prey to water to eat. They are commonly seen in the shade or wading in pools to cool off.
5. Since white tigers have pigmented stripes and blue eyes, they are not albinos.
6. It is estimated that there are less than 3,000 Bengal tigers left in the wild.
