Female cowbirds lay their eggs in other birds’ nests. They usually damage or remove one of the host bird’s eggs first, replacing it with their own egg. The cowbird egg has a short incubation period and usually hatches before the other eggs, demanding more food from the parent birds and decreasing the survival success of the other chicks.

Step 1:Let's solve this step by step:
Step 2:: Understand the Scenario
The description provides key details about cowbird reproductive behavior: - Cowbirds lay eggs in other birds' nests - They often damage or remove a host bird's egg - Cowbird eggs hatch quickly - Cowbird chicks demand more food from host parents - This behavior reduces survival chances of host bird's chicks
Step 3:: Analyze Symbiotic Relationship Characteristics
A symbiotic relationship involves interaction between two different species where: - One species benefits - The other species is harmed or negatively impacted
Step 4:: Identify Relationship Type
In this scenario: - Cowbirds benefit by:
Step 5:
Avoiding parental care
Step 6:
Ensuring offspring survival - Host birds are harmed by:
Step 7:
Loss of their own eggs
Step 8:
Reduced survival of their biological offspring
Step 9:
Expending energy feeding a non-related chick
Step 10:: Classify Symbiotic Relationship
This description precisely matches the definition of **parasitism**: - One species (cowbird) benefits - The other species (host bird) is harmed - The relationship is one-sided and detrimental to the host
Final Answer
**Parasitism**
