In its formative stages, behavioral studies were mostly observational till the classic work of Lorenz, tin Bergen and Frisch catapulted them into Nobel laureates. This had a cascading effect on research on animal behavior resulting in intense studies in several areas of behavior mainly information acquisition (neuroethology) and transfer (communication),ecological aspects (habital related, foraging strategies, migration, predator-prey interactions, population ecology etc.), socio-biology (parent-filial interaction, co-operation & conflict, grouping & dispersion, social organization etc.) reproductive strategies, evolutionary aspects (kin selection, altruism, life history strategies etc.), physiology (behavioral endocrinolog...

Attempts to potentiate anticoagulants for effective rodent control is a new concept with very few studies. Experiments using two non-steroid anti-inflammatory, drugs namely ibuprofen and phenylbutazone at 80 mg/kg and 50 mg/kg body weight respectively to potentiate the action of two second generation anticoagulants, brodifacoum and bromadiolone yielded positive results for Rattus rattus. The drugs reduced the lethal dose required for 100% mortality as well as days to death. Field trials confirmed laboratory findings

The small size of this cereal at all stages of its ripening makes it attractive for the small, seed-eating birds. Considerable damage also is inflicted during early stages of growth when germinating seedlings are depredated by grainivores, and several species of aquatic birds trample the fields in search of food. The migratory blackbirds (Age/aius species and others) eat various grains across the U.S.A. and Mexico, while huge numbers of red-billed weaver bird (Que/ea que/ea) account for grain losses up to 20% in several rice-growing African countries (Efferson, 1952). Although rice is the staple food for the majority of India, information available on bird damage to paddy is inadequate. Ali et aI., 1976) are the recognized pests of rice. A host of insectivorous birds prey upon the abundant insect pests of rice. Studies on ecology of rice field birds and their foraging patterns will aid in formulating the best possible measures to p...

Both the rodenticides induced poison aversion after single ingestion of sub lethal quantities, while bait shyness towards zinc phosphide lasted 170 days, racer produced poison shyness persisted upto 120 days. Based on these results it may be concluded that poisoning M. platythrix with zinc phosphide and vacor should be done for a single day only and residual population be killed by other means. Secondly control of M. platythrix by zinc phosphide poisoning should not be repeated till 170 days and that of racer till 120 days.

On the 10th day changes in the weight, ascorbic acid, and cholesterol levels of liver were estimated. In submissive males, females of male-female encounter and intruders, adrenals hypertrophied. Liver weight remained unaltered. Ascorbic acid levels increased in both members of heterosexual pair, residents and intruder but decreased in subordinates compared to controls. Cholesterol increased in subordinate males and stressed females.
