| Sumario: | Freshwater birds are important in the floodplains because its role in trophic nets and their influence on distribution of other organisms. In the Parana riverine system alnost four guilds way are identified: 1-Birds feeding while walking; 2-Birds feeding swimning of diving; 3-Birds that see their food flying or from snare for birds; 4-Birds that capture their food on stems and leanes. Therefore, they live in relationships to the landscape units that are also influenced by the water level fluctuation as a macrofactor that determine fast influence on the distribution and abundance of bird communities. The amplitude, frequency, and phase recurrence whithin the hydrological regime conform a key factor for understanding the amplitude of niches, and periodicity patterns of aquatic birds inhabiting on a very open environments where the seasonality are mainly conferred by hydrological pulses. |
