Many shore birds such as sanderling (Calidris alba), turnstones, curlews, plovers and rails, are also pellet casters
because of their diet, which consists of mainly invertebrate prey such as crustaceans, worms and molluscs. In fact,
pellet-analysis has been conducted on the common redshank (Tringa totanus), giving details on mudflat prey that are
consumed by these sandpipers (Sanchez et al., 2005). Such analyses have also been conducted on curlew sandpipers
(Calidris ferruginea), grey plovers (Pluvialis squatarola) and common greenshank (Tringa nebularia) (Kalejtab, 1993).
