Diet Analysis of Wetland Passerine Nestlings Using Neck Collars or Faecal Sampling Produces Similar Results

摘要: Two methods are commonly used to study the diet of nestling passerines: neck collar method and faecal sampling. Most studies apply either method, however, few methodological comparing both exist mainly limited farmland birds. Furthermore, existing only include high-level taxonomic categories. Here, we compared using two wetland species, Reed Bunting Emberiza schoeniclus Sedge Warbler Acrocephalus schoenobaenus, included family level as a lower prey level. We found no differences between in dietary composition categories (mainly orders) small some orders at Hence, recommend less invasive easily accessible sampling rather than use collars studies.
