PhysOrg Posted August 21, 2013 Share Posted August 21, 2013 Like cuckoos, honeyguides are parasitic birds that lay their eggs in other birds' nests and dupe them into raising their young.

Rather, it appears to have evolved to trick other honeyguides who would otherwise destroy the eggs because of fierce competition for host nests. The new research is published today, 21 August, in the journal Biology Letters. Read the full article on PhysOrg Link to comment Share on other sites More sharing options...
