Answer:
The relationship between the Cuckoo Bird and the Warbler is a parasitic symbiotic relationship.
Step-by-step explanation:
The Warbler lays their eggs in the Cuckoo bird's nests that their offspring can be cared for by the other bird. The Warbler benefits by not having to care for their young while the Cuckoo bird is harmed by having to care for the extra birds in their nests.
