Provide supplementary food for kingfishers to increase reproductive success
A controlled study of breeding pairs of belted kingfisher Ceryle alcyon in Colorado, USA (Kelly & Van Horne 1997), found that birds that nested earlier had heavier nestlings and were more likely to renest in the event of nest failure. In 1994 and 1995, food supplementation from early in the prebreeding season (8 March) was associated with earlier nest initiation. However, no supplemented nests occurred earlier than the earliest nests in 1992, in which there had been no feeding stations. A smaller amount of food started later in the season (20 April) in the previous year had been without effect.
