Analyses the distribution of Calidris alpina from variations in the numbers of birds and their age ratios as determined in 6 localities. Migration routes are also analysed. Results are discussed in relation to the theory of habitat distribution of Fretwell & Lucas (1970).-from Authors


... The fact that proportional abundance was greatest for the same subsite at both tidal stages for the wader species (Redshank and Grey Plover) suggests that some of the birds may have been foraging preferentially close to their roost sites. This has been shown in previous studies of Oystercatcher (Swennen 1984) and Dunlin Calidris alpina (Have et al. 1984, Dias et al. 2006a where higher status birds tended to roost closer to the best feeding areas. This strategy minimises the distance between roosting and feeding areas and reduces the energy costs of flying between sites (Rogers 2003). ...
