Wintering bald eagles at Nankoweap Creek t . A H'imeli"g bald f'aR/f' ;n 'he wild of the Gmml CallYou by Robert !\(esla US. Fish ami Wildlife Service Approximately 200 to 300 bald E'agle~ (Haliaeetus leucocephalus) mip;r"te south from the Northern States and Canada to over winter along rivers and lakes in Arizona. The confluence of Nankoweap Cret'k and the Colorado River is the onl}' area in the Grand Canyon where bald l'agles can be fOW1d consistently during the winter months, duE' to thl:'" rainbow trout spawn. \Vith the completion of Glen Canyon Dam. the character of the Coloritdo River below the Dam changed from it turbid stream that supported a native, warm water fishery, to a cold, clear stream that supports a largely non-native, cold water fishery. Rainbow trout that inhabited tributaries and those that were subsequently slocked quickly colonized the River under these new conditions. Shortl}' after the trout had established them.c;elves they started spawning in it few small tributaries to the Colorado River. In the mid.1970's rainbow were fust observed to be spa,..Tting in Nankoweap Creek, and by the mid-1980's 1500 spawning rainbow trout were counted in the lower portion of the creek. In response hl the increase of spawning trout small numbt>r~ of uilld eagles began wintering along the River in the area of the Creek. By winter 1990 as many as 26 eagles were observed at the mouth of the Creek feeding on spawning trout. The rainbow trout spawn at Nankoweap Creek now supports the largest conCE'ntration of wintering bald eagles in the southwE'st.lf the trout spawn continues at its present level, future years will note an increac;e in the wintering population of billd eilgles ill Nankoweilp.
