A family of Reed Warblers Acrocephalus scirpaceus is shown searching for small invertebrates in a reed-bed. The well-grown chicks are old enough to feed themselves and they closely resemble their parents.
Translated from Vroege Vogels radio in the Netherlands today:
Like father like daughter
From her childhood on Anne Kwak was taken by her father [Robert Kwak] to a pond. He was there to count birds, she was there to play, because Anne was not interested in birds. Twenty-five years later they are still there, because Anne now is investigating the reed warbler.
Robert is a biologist and works as head of the conservation department of Birdlife in the Netherlands. He specializes in waterfowl.
