Climate change may harm populations of migrating birds by advancing 
the date when their food supply peaks.

Dutch biologists found a large drop in populations of the migratory 
pied flycatcher, Ficedula hypoleuca.

The small bird winters in West Africa and returns to northern Europe 
in the spring to breed.

As spring arrived sooner, caterpillars - a staple of the birds' diet 
- also emerge earlier.
