There are two things to keep in mind when trying to catch the cheerful little bird.
In this instance, a bird cage should do the job. Where might we find one of those?
If you have the cage and the bird is still agitated when you approach, you might be carrying the black rod.

There are some keys on the ground here.
There is a shiny brass lamp nearby.
There is food here.
There is a bottle of water here.

>>Foof!<<
You are in a debris room filled with stuff washed in from the surface. A low wide passage with cobbles becomes plugged with mud and debris here, but an awkward canyon leads upward and west. In the mud someone has scrawled, "MAGIC WORD XYZZY".
A three foot black rod with a rusty star on an end lies nearby.
OK
You are crawling over cobbles in a low passage. There is a dim light at the east end of the passage.
There is a small wicker cage discarded nearby.

You are in an awkward sloping east/west canyon.
You are in a splendid chamber thirty feet high. The walls are frozen rivers of orange stone. An awkward canyon and a good passage exit from east and west sides of the chamber.
