Time machine with straws

On my window sill is a bird, not an ordinary one but the mother of all birds. And she is rather upset with me.

You see, it all started when I made a time machine with straws and a bird accidentally took it to make her nest.

Now when she laid eggs, one of them accidentally travelled to past and became thr first egg from which all the birds evolved. 

And now here she is demanding me an explanation for straw quality(which btw she stole) and all I want to say is hey my friend, you gave birth to all the birds, including yourself only because of my straws, but she just wont listen.
