Blue jays and robins do not interbreed. assuming the blue jays and robins share the same habitat, describe the possible conditions that keep these birds repoductivly isolated. explain your answer.

The are many behavioural and physiological factors that would prevent different species from mating. Birds in particular have complex mating behaviour, including particular plumage, mating calls and nest constructions. It is therefore highly unlikely that two birds of different species would be found compatible for mating with each other. There may also be physiological barriers to prevent mating, such as incompatible genital organs.
