Tree Species Preferences of Foraging Songbirds During Spring Migration in Floodplain Forests of the Upper Mississippi River: Bird Data We evaluated bird foraging preferences for tree species during spring migration 2010-2013. We used the point center-quarter method to assess relative availability (tree importance values, IV) of tree species and tallied bird foraging observations on tree species as well as recording the phenophase of used trees on five 40 ha plots of contiguous floodplain forest between La Crosse, Wisconsin, and New Albin, Iowa, from 15 April through 1 June 2010-2013. We quantified bird preferences by comparing proportional use of tree species by each bird species to estimates of tree species availability (IV) for all four years and for each year separately. Bird data records contain the plot identity, date, time of the observation,...

Data are counts of birds collected during 3 surveys within 50m at each site using 10 minute point count methods. Vegetation was sampled using a releve technique at the bird count point within 10m of the point.

Four plots were sampled corresponding to the start, 50m, 100m and end points of each transect. At each of these four sample plots, species, diameter at breast height (dbh) and distance from the center of the plot were recorded tor trees (>8cm dbh) and saplings (≤8cm dbh). Number of standing snags (>8cm dbh and over 2 m tall) within 25m of the plot center were counted. Total basal area of each plot was estimated using a size 10 angle gauge and averaged over the four plots in each transect. As well, height of a representative canopy tree and understory...
