BOTH C (2011) Starlings Sturnus vulgaris kleptoparasitising godwits Limosa spp. LIMOSA 84 (1): 32-36.
Birds forage in different ways and within species there can be
quite some flexibility in foraging behaviour depending on
ecological conditions. Here I describe how European Starlings
kleptoparasitise on Bar-tailed and Black-tailed Godwits in the
summer of 2010 on the island of Terschelling. At least four individual
Starlings specialised on stealing prey caught by the
godwits while foraging on meadows. They sometimes took
prey items out the bills during handling by the godwits or
chased them away from sites where they found a prey item.
The godwits seemed to be aware of the threat posed by the
Starlings since they chased Starlings coming too close. This is
not the first observation of kleptoparasitism by Starlings, although
it is probably rare. My hypothesis for why they performed
this behaviour is that the spring and summer of 2010
were exceptionally dry, causing soil-dwelling invertebrates to
be out of reach for foraging Starlings.
