Expansion into an Herbivorous Niche by a Customary Carnivore: Black-Tailed Godwits Feeding on Rhizomes of ZOSTERA at a Newly Established Wintering Site
In expanding populations, individuals may increasingly be forced to use sites of relatively low quality. This process, named the "buffer effect," was previously described for the Black-tailed Godwit (Limosa limosa islandica) in its use of nonbreeding sites in Great Britain and of breeding...

In expanding populations, individuals may increasingly be forced to use sites of relatively low quality.
