Seasonal mean perch height ± standard deviation of Iberian bullfinches in NW Spain, including all types of plant and ground, and available mean maximum hedge height ± standard deviation (AV.). Data correspond to 2001‒2006. Winter: December to February. Spring: March to May. Summer: June to August. Autumn: September to November. n: number of records. Each “overall” record refers to an individual perched on a specific substrate, sighted and identified by sex and age, whether eating or not. Each “feeding” record refers to the same, but only if the individual was eating (overall records include feeding records). Number of individuals sighted: winter—166 males, 117 females; spring—368 m, 235 f; summer—265 m, 185 f, 696 juveniles; autumn—179 m, 132 f, 164 j. See "Methods" for further clarification of record definition regarding substrate use, and for detailed information on assessment of available mean maximum hedge height
