INTERACTION MECHA-NISMS OF MIGRATING WADERS AND THEIR FOOD OBJECTS IN CONDITIONS OF ATHROPOGENIC TRANSFORMED WATER RESERVOIRS OF TAMBOV REGION
It was found out how the distribution of waders migrating through the sewage ponds depends on characteristics of their diet. To understand this we studied the dynamics of waders’ distribution, the distribution of their food resources, feeding behavior of birds and the biometrics of food objects including the contents of bird stomachs and gullets. The basis of diet consists of large mass of insect species, mostly of larger ones. The distribution of birds depends on abundance, biomass, taxonomic composition and linear size of food objects.
