Climate of talsari
The place receives 156.84 cms rainfall throughout the year. During the summer, the temperature is high and sometimes reaches 40 °C. During the winter, the mercury stands around 14 °C.
Brief topography of talsari
Talsari is situated at the confluence of Subarnarekha estuary with the sea. The Subarnarekha estuarine delta is the westernmost unit of the topographic expression in the present coastal plain. A degraded tract of mangrove swamp is still in existence around the estuarine link of Talsari tidal and intertidal flats.
Mostly sand dunes are scattered in patches and have been modified into small islands which are further interconnected by rivers. Extensive trees, mostly Casuarina have been found in vast stretched of these islands.
Soil patterns includes sandy loamy and textures are quite smooth for subtle vegetation growth but not for cultivation.
At the farthest points of the landmasses there are docking sites for boats and few settlements can be also seen but whether they are inhabited or not remains a question.

CRAB BEHAVIOR STUDY AT TAJPUR
Crabs are distinct group of crustaceans found exclusively if both water and as well as land and hence they are also called amphibians.
The study of crab behavior pattern was exclusively chosen as one of the intrincate faunal diversity observations in our field study and for this, Tajpur ,a beach ,a not so distant place from digha was chosen for crab behavior study. It has a climate and topography quite similar to talsari.

AVIFAUNA STUDY AT ALANKARPUR
Diversity of avifauna is one of the most important ecological indicators to evaluate the quality of habitats. Now-a-days, avifaunal diversity has been decreasing due to the destruction of natural habitats and human disturbances. Random destruction of natural habitats by cutting nesting trees and foraging plants for commercial use of woods and lands are the main factor responsible for narrow down in avian foraging habitat and their nesting sites. Thus, many species of birds may be forced to inhabit in the urban areas and constrain them to breed there. Birds are essential animal group of an ecosystem and maintain a trophic level. Therefore, detail study on avifauna and their ecology is important to protect them.
Apart from studying and analyzing the nature and behavior of birds in forest region of talsari and effort to study the behavior of birds were done at a small village name alankarpur near Digha.
The main objective was to study the behavior of birds in anthropogenic conditions.
The time was usually from 6:30am to 8:30am when the surroundings are silent thus the time is favorable and plenty of birds will be available.
