Seek out a sunny picture -
Remember you're on SE -
And on that sunny picture,
Figure out what you can;
You are a less capital idea
Than those who follow you.
What kind of birds appear?
When you're on SE, where would you find a picture?
Your answer can take the form of an actual picture (which has birds in). The challenge is to find the correct picture, not to identify the birds.
Hint 3 (like Hint 1, but bigger):
When you upload a picture while making a post on SE, where will the URL of that picture be?
