Humming bird

Today I saw a hummingbird on my way home but it was gone before I could get put my camera! In bogota there are some really beautiful, colourful flowers in the streets and gardens. Around the new flat they've been trying hard to plant trees and flowers to make the neighbourhood look more green! But I still would like to see more trees! The city is really polluted and walking around you can smell and taste the fumes. There are huge trucks and buses which let out black smoke.
So I'll start with my balcony and see how I can encourage lots of tree planting in the city!
