Bird food plants Bird food plants Bird food plants are certain trees, shrubs and herbaceous plants bear fruits which afford food for birds. These have been discovered by observation, and by the scientific examination of the contents of birds' stomachs. By planting those species, therefore, which have been proved most desirable and that are suited to the climate and soil of the chosen location, birds can be attracted to the vicinity of dwelling houses or to any other desired spot as a copse or shrubbery, or, on the other hand, lured away from valuable orchards, since they appear to like best arid, bitter,
Birds of the Danube Delta Birds of the Danube Delta Following an almost two-decade (1951–1970) research of the Danube Delta territory, 274 bird species were identified of which 176 were brooding (sedentary and migratory) and 98 non-brooding ones (winter, passage, erratic, and accidental birds). The species of brooding birds occurring in the Danube Delta were classified into 12 main biotopes, the classification criterion being represented by the nesting place where they show the greatest relative density. As to their dynamics, the brooding birds include: 44 sedentary species and 132 migratory ones. The great number of migratory species is explained by the optimal conditions of nesting
