Data are presented on nearly 18,000 bird-captures involving 125 species banded between 1992 and 2005 at two Platte Valley study areas in central and western Nebraska. Weight data for more than 1 1,500 individuals of 74 species are summarized by age, sex and banding site, including several species having larger samples than in any previously published reports. Breeding evidence was obtained for 67 species in one or both locations, and 108 of the total 125 species banded were migrants, 71 percent of which were Neotropical migrants. The largest banding totals were obtained at Cedar Point Biological Station, in Keith County, but large numbers were also obtained at sites in Dawson County, about 100 miles to the east. Hybrids of four sympatric species-pairs (Lazuli & Indigo Bunting, Black-headed & Rose-breasted Grosbeak, Spotted & Eastern Towhees, Bullock's & Baltimore Oriole) were documented at these locations.
