Ornithology on the Route
HABITATS EAST ARM ORNITHOLOGICAL ROUTE
On this route you can observe 3 habitats:
Rice monocultures cover thousands of hectares of the Isla Menor and are based on large plots leveled by laser technology. It is a modern and highly mechanized agricultural system, with treatments with airplanes, tractors and harvesters. In early summer the plots are flooded just before the rice is sown. In summer, crops are kept in continuous soaking until harvest in early October, creating artificial wetlands at the driest time of the year. In the rest of the year they usually stay moist from the rain. An extensive network of irrigation and drainage channels, as well as pipes cross the crops, providing some landscape and ornithological variety. Rice paddies usually shelter a large amount of aquatic invertebrates that powerfully attract birds, especially waders. The remains of the harvest also form a food resource for them. The rice paddies therefore serve, especially for the foraging of wild birds such as different species of herons, egrets and egrets, storks, moritos, canastera, sparrows, swallows and airplanes. On the edges and edges of the plots they breed vultures, cogujadas and terreras.
Old river arm:
In the Natural Paraje Brazo del Este is maintained a natural palustre vegetation of cañizo, aeneas, reeds and humming. Water runs in times of heavy rains prevent the river arm from being completely covered with vegetation, always keeping some water open. Here they breed many species that feed in the surrounding rice paddies, in addition to other typical species of palustre vegetation such as avetoro, avetorillo, carreders, carricerines, look for its, bastard nightingale, pale brask, bird moscon, kingfisher, rascon, harangued laguneroas well as grilled pig and other analytes, etc… It is in the Eastern Arm that the yellow weavers and cebecinegro as well as poultry,allocton species that have recently colonized the marshes.
The Guadalquivir River as it passes through the Isla Menor is more or less regulated and channeled. It still maintains level fluctuations based on rainfall throughout its watershed. It is a wide river and more or less deep water. The margins are covered in some sections by pipes, willows and eucalyptus trees. On the river it is easy to see cormorants, somormujos, ducks and seagulls.
