Data on the sex and age composition of Bramblings Fringilla montifringilla during autumn migration and winter in Europe
<p><strong>Abstract</strong></p> <p>Bramblings <em>Fringilla montifringilla</em> are known to vary in winter distribution according to sex and age (differential migration). This pattern is complicated by the large yearly fluctuation in their preferred winter food, beech seeds. In beechmast areas, large concentrations of Bramblings occur, and their sex and age composition differs from that of winters without a beechmast. Here we present data on the sex and age composition of Bramblings during autumn migration and winters with and without beechmast, mainly from Switzerland, supplemented with data from northern and southern Europe.</p> <p> </p> <p><strong>Literature cited in the Excel-file</strong></p> <p>Arizaga J, Zuberogoitia I, Zabala J, Crespo A, Iraeta A, Belamendia G (2012) Seasonal patterns of age and sex ratios, morphology and body mass of Bramblings <em>Fringilla montifringilla </em>at a large winter roost in southern Europe.

Data from: Sora (Porzana carolina) autumn migration habitat use
Palustrine wetland management across the United States is often conducted under a moist soil management framework aimed at providing energetic resources for non-breeding waterfowl. Moist soil management techniques typically include seasonal water-level manipulations and mechanical soil disturbance to create conditions conducive to germination and growth of early successional, seed-producing wetland plants. The assumption is that providing stopover and wintering habitat for non-breeding waterfowl will also accommodate life history needs of a broader suite of migratory waterbirds including shorebirds, wading birds, and marsh birds. Although studies of wetlands provide some evidence to support this assumption for shorebirds and wading birds, there is less information on how other marshbirds, respond. Sora (Porzana carolina) are a species of migratory rail that depends on wetlands year round as it migrates across North America. It is a species for which the consequences of wetland management decisions directed toward non-breeding waterfowl, is unknown. We conducted nocturnal surveys on 10 public properties in Missouri, USA during autumn migration from 2012-2016 to examine Sora habitat use in wetland impoundments managed to enhance production of moist soil vegetation. We found a positive relationship with Sora presence and mean water depth and annual moist soil vegetation; Sora used, on average, deeper water than was available across surveyed impoundments and used locations with a higher percentage of annual moist soil vegetation than was available. We found a negative relationship with Sora use and upland vegetation, woody vegetation, and open water. We found Sora using deeper water than have previously been reported for autumn migration and that moist soil management techniques used on Missouri's intensively-managed public wetland areas may be compatible with Sora autumn migration stopover habitat requirements.
