It’s world sparrow day today, 20th March. Sparrows have been those winged companions of humans for a long time. Over the recent years there has been a sharp decline in the sparrow sightings though- probably owing to the mindless advancement of their human companions?

Here are some images from our kitchen window, and ideas on how you can re-friend a sparrow.

The male house sparrow below is acting as a sentinel (watch), while the others are enjoying the bird feed.

For the bird feed you can simply recycle a plastic container and a spoon. The size of the hole and the shape of the spoon regulates the flow of the grains from the container. The bird feed in the images above was made by sarah.

Male house sparrows have a black  throat patch, which is known as a badge. Studies show that males with larger badge sizes are dominant among their flocks. Other than acting as a status signal of dominance, the badge size also favour the male sparrows in obtaining a mate.
