This is 'Sonny' the UV Budgie. He goes online and looks up weather data from the Met Office API for your area - specifically for UV Rays, which can cause sunburn and increase the risk of skin cancer.
Did you know, even on a cloudy day, 80% of harmful UV rays can pass through, so it's not about it being 'sunny', as much as the UV Index, that you and your family need to be aware of.

The project is in fact and 'evolution' or 'follow-up' the the Air Quality Canary. Both projects created for RS Components / DesignSpark.
