Thrush anvils are calcium source hotspots for many bird species
Original language description
Calcium is one of the most important elements determining reproductive success in birds, and snail shells are a well-known source of calcium for egg laying females. In Europe, song thrushes, Turdus philomelos, break snails open at locations called anvils, eat the soft parts and leave the broken shells. Based on observational studies in 2011 2017 in western Poland, we showed that thrush anvils were visited by 54 other bird species (mainly smaller species) that collected the broken shell fragments. The frequency of visits to anvils differed among species and changed over the course of the breeding season, but anvils were especially used by females during the pre-laying period. Our study is the first description of such widespread exploitation of thrush anvils by other bird species, and we think that this phenomenon has been overlooked owing to the difficulties in recording anvils located, for example, on single small stones, stumps of felled trees and man made objects such as glass bottles.
