(Passermontanus) body w e ight and BM R ( basal m etabolic rate) as w ell as the ir physiolog ical adjusting m echan ism. The T ree Sparrow s fed regu larly were selected to be the control group ( 0D, D for day) and four groups of sparrow s w ith sam e food- intake but different hunger hours ( 1D, 3D, 5D and 7D) to be the objects of study and acclmi ation. T he results show s that there ex ists m arked linear relationsh ip bewt een the body w eight and BMR ( r= 015 12, P = 0100 1). T here is no d istinct d ifference as for the BM R level of un it w eight among the five groups of T ree Sparrow s, but d istinct between the 5D and 7D team of body. s BMR (P 0105). T ree Sparrow s of the control group gain w e ight
