You claimed they have purpose. Burden is on you to support your claim. But since we've descended into a Gish-esq discussion over why you feel you shouldn't have to provide a direct answer to a direct question, I'll take that as a tacit admission you can't support the claim, and know it.

Here is my response regarding purpose.
Purpose
The first passage from Isaiah relates to the whole of creation, birds included. The earth was created to be inhabited, that is why it is not barren like Mars.
Isaiah 45:18 He who fashioned and made the earth, he did not create it to be empty, but he
formed it to be inhabited.
The verse in Ephesians relates to the higher purpose which you and I have.
Ephesians 2:10 For we are God’s handiwork,
created in Christ Jesus to do good works,
which God prepared in advance for us to do.
The verse in Colossians tells us that the purpose of all creation is for God.
Colossians 1:16 For in him all things were created: things in heaven and on earth, visible and invisible, all things have been created through him and
for him.
You may not find these answers acceptable in that they are all drawn from Scripture. This is understandable because outside of God's Word, there is no suggestion of purpose.
No purpose
There is a 'purposeless purpose' associated with biological evolution. It is simply this. "The optimum outcome is that the organism can breed and continue to survive."
Of those who recognize evolution as factual, the vast majority accept that the Theory of Evolution implies that no guidance whatsoever is given to the process. It has no actual purpose. Evolution has no end goal. It is understood to proceed slowly, functioning solely through random chance.
Whether it is a man, a bird, a mouse, or a microbe — all are equal in respect to evolution. The optimum outcome is that the organism can breed and continue to survive.
