Surprise in Urban Balcony

Blinky usually doesn't care about the bamboo. Yet, he got very excited today. It seems something has caught his eye...

Something near the top of the bamboo plants.

FWAH!!
A bird's nest!!

And it's almost completed. I can't believe I haven't detected it earlier.

We are expecting little eggs... then little birdlings...

Meanwhile, I will attempt to keep the cats away from the nest. Blinky is too curious.
